RESUMO
OBJECTIVE: Carotid web (CaWeb) is a rare form of fibromuscular dysplasia that can produce embolic stroke. Misdiagnosis of symptomatic CaWeb as "cryptogenic stroke" or "embolic stroke of unknown source" is common and can lead to recurrent, catastrophic neurologic events. Reports of CaWeb in the literature are scarce, and their natural history is poorly understood. Appropriate management remains controversial. METHODS: CaWeb was defined as a single, shelf-like, linear projection in the posterolateral carotid bulb causing a filling defect on computed tomography angiography (CTA) or cerebral angiography. Cases of symptomatic CaWeb at a single institution with a high-volume stroke center were identified through collaborative evaluation by vascular neurologists and vascular surgeons. RESULTS: Fifty-two patients with symptomatic CaWeb were identified during a 6-year period (2016-2022). Average age was 49 years (range, 29-73 years), 35 of 52 (67%) were African American, and 18 of 52 (35%) were African American women under age 50. Patients initially presented with stroke (47/52; 90%) or transient ischemic attack (5/52; 10%). Stenosis was <50% in 49 of 52 patients (94%) based on NASCET criteria, and 0 of 52 (0%) CaWebs were identified with carotid duplex. Definitive diagnosis was made by CTA examined in multiple planes or cerebral angiography examined in a lateral projection to adequately assess the posterolateral carotid bulb, where 52 of 52 (100%) of CaWebs were seen. Early in our institutional experience, 10 of 52 patients (19%) with symptomatic CaWeb were managed initially with dual antiplatelet and statin therapy or systemic anticoagulation; all suffered ipsilateral recurrent stroke at an average interval of 43 months (range, 1-89 months), and five were left with permanent deficits. Definitive treatment included carotid endarterectomy in 27 of 50 (56%) or carotid stenting in 23 of 50 (46%). Two strokes were irrecoverable, and intervention was deferred. Web-associated thrombus was observed in 20 of 50 (40%) on angiography or grossly upon carotid exploration. Average interval from initial stroke to intervention was 39 days. After an average follow-up of 38 months, there was no reported postintervention stroke or mortality. CONCLUSIONS: To our knowledge, this is the largest single-institution analysis of symptomatic CaWeb yet reported. Our series demonstrates that carotid duplex is inadequate for diagnosis, and that medical management is unacceptable for symptomatic CaWeb. Recurrent stroke occurred in all patients managed early in our experience with medical therapy alone. We have since adopted an aggressive interventional approach in cases of symptomatic CaWeb, with no postoperative stroke reported over an average follow-up of 38 months. In younger patients presenting with cryptogenic stroke, especially African American women, detailed review of lateral cerebral angiography or multi-planar, fine-cut CTA images is required to accurately rule out or diagnose CaWeb and avoid recurrent neurologic events.

OBJECTIVE: Complex endovascular juxta-, para- and suprarenal abdominal aortic aneurysm repair (comEVAR) is frequently accomplished with commercially available fenestrated (FEVAR) devices or off-label use of aortoiliac devices with parallel branch stents (chEVAR). We sought to evaluate the implantable vascular device costs incurred with these procedures as compared with standard Medicare reimbursement to determine the financial viability of comEVAR in the modern era. METHODS: Five geographically distinct institutions with high-volume, complex aortic centers were included. Implantable aortoiliac and branch stent device cost data from 25 consecutive, recent, comEVAR in the treatment of juxta-, para-, and suprarenal aortic aneurysms at each center were analyzed. Cases of rupture, thoracic aneurysms, reinterventions, and physician-modified EVAR were excluded, as were ancillary costs from nonimplantable equipment. Data from all institutions were combined and stratified into an overall cost group and two, individual cost groups: FEVAR or chEVAR. These groups were compared, and each respective group was then compared with weighted Medicare reimbursement for Diagnosis-Related Group codes 268/269. Median device costs were obtained from an independent purchasing consortium of >3000 medical centers, yielding true median cost-to-institution data rather than speculative, administrative projections or estimates. RESULTS: A total of 125 cases were analyzed: 70 FEVAR and 53 chEVAR. Two cases of combined FEVAR/chEVAR were included in total cost analysis, but excluded from direct FEVAR vs chEVAR comparison. Median Medicare reimbursement was calculated as $35,755 per case. Combined average implantable device cost for all analyzed cases was $28,470 per case, or 80% of the median reimbursement ($28,470/$35,755). Average FEVAR device cost per case ($26,499) was significantly lower than average chEVAR cost per case ($32,122; P < .002). Device cost was 74% ($26,499/$35,755) of total reimbursement for FEVAR and 90% ($32,122/$35,755) for chEVAR. CONCLUSIONS: Results from this multi-institutional analysis show that implantable device cost alone represents the vast majority of weighted total Medicare reimbursement per case with comEVAR, and that chEVAR is significantly more costly than FEVAR. Inadequate Medicare reimbursement for these cases puts high-volume, high-complexity aortic centers at a distinct financial disadvantage. In the interest of optimizing patient care, these data suggest a reconsideration of previously established, outdated, Diagnosis-Related Group coding and Medicare reimbursement for comEVAR.

OBJECTIVE: Poor ergonomic posture during interventional procedures might lead to increased physical discomfort and work-related musculoskeletal disorders. Adjunctive equipment such as lead aprons (LAs) has been shown to increase ergonomic posture risk (EPR). The objective of this study was to evaluate the effectiveness of StemRad MD (StemRad Ltd., Tel Aviv, Israel), a weightless exoskeleton-based radiation protective ensemble, in reducing EPR on the operator using wearable inertial measurement unit (IMU) sensors. METHODS: A prospective, observational study was conducted at an academic hospital. Inertial measurement unit sensors were affixed to the upper back of 9 interventionalists to assess ergonomic risk posture during endovascular procedures while wearing a traditional LA or the StemRad MD radiation protection system. Total fluoroscopy time, procedure type, and ergonomic risk postures were recorded and analyzed. RESULTS: Twenty-one cases were performed with StemRad MD and 30 with LAs. Mean procedure time for the StemRad MD procedures was 48.4±23.3 minutes (range: 24-106 min), and for LA procedures, it was 34.66±25.83 minutes (range: 6-100 min) (p=.060). The operators assumed low-risk ergonomic positions in 96.1% of StemRad MD cases and in 62.9% of LA cases (p=.001), and high-risk ergonomic positions in 0% and 6.2%, respectively (p=.80). Mean EPR score for StemRad MD was 1.16, and for the LA, it was 1.49 (p=.001). CONCLUSIONS: StemRad MD significantly reduces the EPR to the torso compared with a LA-based radiation protection system. CLINICAL IMPACT: Poor ergonomic posture during interventional procedures might leas to work-related musculoskeletal disorders for healthcare workers. StemRad MD, a weightless, exoskeleton-based radiation protection system was shown to significantly reduce ergonomic posture risk to the torso compared to conventional lead aprons. This might lead to reduced physical discomfort for procedure-based specialists.
RESUMO
BACKGROUND: A pre-existing nationwide nursing shortage drastically worsened during the pandemic, causing a significant increase in nursing labor costs. We examined the financial impact of these changes on department of surgery financial margins. STUDY DESIGN: Operating room, inpatient, and outpatient financial metrics were analyzed. Monthly averages from a 14-month control cohort, January 2019 to February 2020 (pre-COVID-19), were compared with a 21-month cohort, March 2020 to November 2021 (COVID-19). True revenue and cost data from hospital accounting records, not estimates or administrative projections, were analyzed. Statistics were performed with standard Student's t -test and the Anderson-Darling normality test. RESULTS: Monthly surgical nursing costs increased significantly, with concomitant significant decreases in departmental contribution to margin. No significant change was observed in case volume per month, length of stay per case, or surgical acuity, as standardized by the US Centers for Medicare & Medicaid Services Case Mix Index. To obviate insurance payor mix as a variable and standardize cost data, surgical nursing expense per relative value unit was analyzed, demonstrating a significant increase. Hospital-wide agency nursing costs increased from $5.1 to $13.5 million per month (+165%) in 2021. CONCLUSIONS: Our results demonstrate a significant increase in surgical nursing labor costs with a resultant erosion of department of surgery financial margins. Use of real-time accounting data instead of commonly touted administrative approximations or Medicare projections increases both the accuracy and generalizability of the data. The long-term impact of both direct costs from supply chain interruption and indirect costs, such as limited operating room and ICU access, will require further study. Clearly this ominous trend is not viable, and fiscal recovery will require sustained, strategic workforce allocation.

OBJECTIVE: Aberrant subclavian arteries (aSCAs), with or without aortic pathology, are uncommon. The purpose of the present study was to review our experience with the surgical management of aSCA. METHODS: We performed a retrospective review of patients who had undergone surgery for an aSCA between 1996 and 2020. Symptomatic and asymptomatic patients were included. The primary end points were ≤30-day and late mortality. The secondary end points were ≤30-day complications, graft patency, and reinterventions. RESULTS: A total of 46 symptomatic and 3 asymptomatic patients with aSCA had undergone surgery (31 females [62%]; median age, 45 years). An aberrant right subclavian artery was present in 38 (78%) and an aberrant left subclavian artery in 11 patients (22%). Of the 49 patients, 41 (84%) had had a Kommerell diverticulum (KD) and 11 (22%) had had a concomitant distal arch or proximal descending thoracic aortic aneurysm. Symptoms included dysphagia (56%), dyspnea (27%), odynophagia (20%), and upper extremity exertional fatigue (16%). Five patients (10%) had required emergency surgery. The aSCA had been treated by transposition in 32, a carotid to subclavian bypass in 11, and an ascending aorta to subclavian bypass in 6. The KD was treated by resection and oversewing in 19 patients (39%). Fifteen patients (31%) had required distal arch or proximal descending thoracic aortic replacement for concomitant aortic disease and/or KD treatment. Thoracic endovascular aortic repair was used to exclude the KD in six patients (12%). Seven patients (14%) had undergone only bypass or transposition. The 30-day complications included one death from pulseless electrical activity arrest secondary to massive pulmonary embolism. The 30-day major complications (14%) included acute respiratory failure in three, early mortality in one, stroke in one, non-ST-elevation myocardial infarction in one, and temporary dialysis in one patient. The other complications included chylothorax/lymphocele (n = 5; 10%), acute kidney injury (n = 2; 4%), pneumonia (n = 2; 4%), wound infection (n = 2; 4%), atrial fibrillation (n = 2; 4%), Horner syndrome (n = 2; 4%), lower extremity acute limb ischemia (n = 1; 2%), and left recurrent laryngeal nerve injury (n = 1; 2%). At a median follow-up of 53 months (range, 1-230 months), 40 patients (82%) had had complete symptom relief and 9 (18%) had experienced improvement. Six patients had died at a median of 157 months; the deaths were not procedure or aortic related. The primary patency was 98%. Reintervention at ≤30 days had been required for two patients (4%) for ligation of lymphatic vessels and bilateral lower extremity fasciotomy after proximal descending thoracic aorta replacement. One patient had required late explantation of an infected and occluded carotid to subclavian bypass graft, which was treated by cryopreserved allograft replacement. CONCLUSIONS: Surgical treatment of the aSCA can be accomplished with low major morbidity and mortality with excellent primary patency and symptom relief.

OBJECTIVE: The financial effects of the coronavirus disease 2019 (COVID-19) pandemic have fundamentally changed the healthcare environment, with hospitals expected to have lost billions in 2021. A preexisting nationwide nursing shortage became drastically worse during the pandemic amid dramatically increasing labor costs. We examined the evolution and financial effects of these changes during repeated pandemic surges within a vascular surgery division at a tertiary medical center. METHODS: Operating room, inpatient unit, and outpatient clinic financial data were examined retrospectively. The monthly averages for a 14-month control cohort before COVID-19 (January 2019 to February 2020) were compared to the averages for seven interval groups of sequential, 3-month cohorts from March 2020 through November 2021 (groups 1-7). RESULTS: The monthly relative value unit (RVU) generation had returned to the mean before the COVID-19 pandemic (2520 RVUs) after an isolated decrease early in the pandemic (group 1; 1734 RVUs). The RVUs ranged from 2540 to 2863 per month for groups 2 to 5, with a slight decline in groups 6 and 7. The average monthly RVUs in the COVID-19 period (2437 RVUs) were nearly equivalent (P = .93) to those for the pre-COVID-19 cohort. An analysis of payor mix demonstrated an increase in commercial and Medicaid payors, with a respective decrease in Medicare payors, during COVID-19. The contribution to indirect, or profit, from inpatient hospital and outpatient clinical revenue showed a drastic decrease in group 1, followed by a swift rebound when the government restrictions were eased (group 2). The total monthly vascular nursing unit expense demonstrated a marked increase with each sequential group during COVID-19, with an average monthly upsurge of +$82,171 (+47%; P < .001). An increase in the nursing labor expenses of +$884 per vascular case (from $1630 to $2514; +54%; P < .001) was observed in the COVID-19 era. The nursing labor costs per patient day had increased from $580 to $852 (+$272; +53%; P < .001). The nursing labor cost per RVU had increased from $69.5 to $107.7 (+$38.2; +55%; P < .001). On a system-wide level, the agency-related nursing costs had increased from $4.9 million to $13.6 million per month (+178%; P < .001) in 2021 compared with 2020. CONCLUSIONS: The COVID-19 pandemic has had severe, nationwide effects on healthcare delivery, exacerbating the deleterious effects of an existing, critical nursing shortage. To the best of our knowledge, the present study is the first detailed analysis of this phenomenon and its effects on a surgical division. Our results have demonstrated a progressive, drastic increase in nursing labor costs during the pandemic, with a resultant sustained erosion of financial margins despite a level of clinical productivity, as measured in RVUs, equal to the prepandemic standards. This precarious trend is not sustainable and will require increased, targeted government funding.

OBJECTIVE: Primary venous leiomyosarcomas (PVL) are rare and pose challenges in surgical management. This study evaluates the clinical outcomes and identifies predictors of survival in our surgical series of PVL. METHODS: A retrospective review was performed of patients who had resection of PVL at three centers between 1990 and 2018. Patient demographics, comorbidities, intraoperative data, survival, and graft-related outcomes were recorded. Survival analysis was performed using Kaplan-Meier curves and Cox proportional hazards regression. RESULTS: Seventy patients with a diagnosis of PVL were identified between 1990 and 2018. Fifty-four patients (77%) had PVL of the inferior vena cava (IVC) and 16 (23%) had peripheral PVL. The mean follow-up for the series was 55.0 months (range, 1-217 months). Fifty-one patients (96%) with IVC-PVL needed caval reconstruction and 3 (4%) had resection only. There were no deaths within 30 days of surgery. Five patients (9%) required early reintervention including one (2%) IVC stent. Sixteen peripheral PVL were identified. Eight patients (50%) had venous reconstructions performed and 8 (50%) had the vein resected without reconstruction. There were no deaths within 30 days. Five-year survival was 57.5% for IVC-PVL and 70.0% for peripheral PVL. Kaplan-Meier survival analysis for IVC and peripheral PVL revealed no difference in overall survival (P = .624) at 5 years. CONCLUSIONS: PVL is a rare and aggressive disease even with surgical resection. We found no difference in survival between IVC and peripheral lesions, suggesting that aggressive management is warranted for PVL of any origin. Management of PVL requires a multidisciplinary approach to provide patients with the best long-term outcomes.

OBJECTIVE: The contemporary medicolegal environment has been linked to procedure overuse, health care variation, and higher costs. For physicians accused of malpractice, there is also a personal toll. The objective of this study was to evaluate the prevalence of and risk factors for involvement in medical malpractice lawsuits among United States vascular surgeons, and to examine the association between these allegations with surgeon wellness. METHODS: In 2018, the Society of Vascular Surgery (SVS) Wellness Task Force conducted a confidential survey of active members using a validated burnout assessment (Maslach Burnout Index) embedded into a questionnaire. This survey included questions related to medical errors and malpractice litigation. De-identified demographic, personal, and practice-related characteristics were assessed in respondents who reported malpractice allegations in the preceding 2 years, then compared with those without recent medicolegal litigation. Risk factors for malpractice allegations were identified (χ2, Kruskal-Wallis tests), and the association between malpractice allegations with wellness was examined. Multivariate logistic regression models were developed to identify independent risk factors for malpractice accusations. RESULTS: Of 2905 active SVS members, 871 responses from practicing vascular surgeons were analyzed. A total of 161 (18.5%) were named in a malpractice lawsuit within 2 years. Malpractice allegations were significantly associated with surgeon burnout (odds ratio, 1.47; 95% confidence interval, 1.01-2.15; P = .041), but not with self-reported depression or suicidal ideation. The nature of malpractice claims included procedural errors (23.1%), failure to treat (18.8%), and error/delay in diagnosis (16.9%). Twenty percent of claims were settled prior to trial, and 19% were dismissed. Defendant vascular surgeons reported a "fair" resolution in 26.4% of closed cases. By unadjusted analysis, factors significantly associated with recent malpractice claims included mean age (51.7 ± 10.0 vs 49.3 ± 11.2 years; P = .0044) and mean years in practice (18.0 ± 10.7 vs 15.2 ± 11.8; P = .0007). Multivariate analysis revealed independent variables associated with malpractice allegations, including on-call frequency (P = .0178), recent medical errors (P = .0189), and male surgeons (P = .045). CONCLUSIONS: Malpractice allegations are common for vascular surgeons and are significantly associated with surgeon burnout. Nearly 20% of survey respondents reported being named in a lawsuit within the preceding 2 years. Our findings underscore the need for SVS initiatives to provide counseling and peer support for vascular surgeons facing litigation.

Little is known about the surgical challenges and outcomes of kidney transplantation (KT) in the face of severe iliac occlusive disease (IOD). We aim to examine our institution's experience and outcomes compared with all KT patients. Retrospective review of our multi-institutional transplant database identified patients with IOD requiring vascular surgery involvement for iliac artery endarterectomy at time of KT from 2000 to 2018. Clinical data, imaging studies, and surgical outcomes of 22 consecutive patients were reviewed. Our primary end-point was allograft survival. Secondary end-points included mortality and perioperative complications. A total of 6,757 KT were performed at our three sites (Florida, Arizona, and Minnesota); there were 22 (0.32%) patients receiving a KT with concomitant IOD requiring iliac artery endarterectomy. Mean patient age was 61.45 ± 7 years. There were 13 (59.1%) male patients. The most common etiology of renal failure was diabetic nephropathy in 10 patients (45.5%) followed by a combination of hypertensive/diabetic nephropathy in five patients (22.7%), and hypertensive nephrosclerosis in three patients (13.6%). The majority ( n = 16, 72.7%) of patients received renal allografts from deceased donors and six (27.3%) were recipients from living donors. Mean time from dialysis to transplantation was 2.9 ± 2.9 years. Mean follow-up was 3.5 ± 2.5 years. Mean length of hospital stay was 6.3 ± 4.3 days (range: 3-18 days). Graft loss within 90 days occurred in two (9.1%) patients, one due to renal vein thrombosis and another due to acute tubular necrosis. Overall allograft survival was 90.1% at 1-year and 86.4% at 3-year follow-up. Overall mortality occurred in 6 (27.3%) patients. Perioperative complications (Clavien-Dindo Grade 2-4) occurred in 13 (59.1%) patients, including 10 (45.5%) with acute blood loss anemia requiring transfusion, 2 (9.1%) reoperations for hematoma evacuation, 1 (4.5%) ischemic colitis requiring total abdominal colectomy, and 1 (4.5%) renal vein thrombosis requiring nephrectomy. IOD patients selected for KT are not common and although challenging, they have similar outcomes to our standard KT patients. The 1- and 3-year allograft survivals were 90.1 and 86.4% versus 96.0 and 90.3% in the general KT patient population. With these excellent outcomes, we recommend expanding the criteria for KT to include patients with IOD with prior vascular surgery consultation to prevent progression of IOD or prevention of wait list removal in select patients who are otherwise good candidates for KT.
RESUMO
PURPOSE: The purpose of this study was to evaluate trends in Medicare reimbursement for common vascular procedures over the last decade. To enrich the context of this analysis, vascular procedure reimbursement is directly compared to inflation-adjusted changes in other surgical specialties. METHODS: The Centers for Medicare & Medicaid Services Physician/Supplier Procedure Summary file was utilized to identify the 20 procedures most commonly performed by vascular surgeons from 2011-2021. A similar analysis was performed for orthopedic, general, and neurological surgeons. The Centers for Medicare & Medicaid Services Physician-Fee Schedule Look-Up Tool was queried for each procedure, and reimbursement data was extracted. All monetary data was adjusted for inflation to 2021 dollars utilizing the consumer price index. Average year-over-year and total percentage change in reimbursement were calculated based on adjusted data for included procedures. Comparisons to other specialty data were made with ANOVA. RESULTS: From 2011-2021, the average, unadjusted change in reimbursement for vascular procedures was -7.2%. Accounting for inflation, the average procedural reimbursement declined by 20.1%. The greatest decline was observed in phlebectomy of varicose veins (-50.6%). Open arteriovenous fistula revision was the only vascular procedure with an increase in inflation-adjusted reimbursement (+7.5%). Year-over-year, inflation-adjusted reimbursement for common vascular procedures decreased by 2.0% per year. Venous procedures experienced the largest decrease in average adjusted reimbursement (-42.4%), followed by endovascular (-20.1%) and open procedures (-13.9%). These changes were significantly different across procedural subgroups (P < 0.001). During the same period, the average adjusted change in reimbursement for the 20 most common procedures in orthopedic surgery, general surgery, and neurosurgery was -11.6% vs. -20.1% for vascular surgery (Pâ¯=â¯0.004). CONCLUSION: Medicare reimbursement for common surgical procedures has declined over the last decade. While absolute reimbursement has remained relatively stable for several procedures, accounting for a decade of inflation demonstrates the true diminution of buying power for equivalent work. The most alarming observation is that vascular surgeons have faced a disproportionate decrease in inflation-adjusted reimbursement in comparison to other surgical specialists. Awareness of these trends is a crucial first step towards improved advocacy and efforts to ensure the "value" of vascular surgery does not continue to erode.

OBJECTIVE: Work-related pain and disability have been reported in the literature among surgeons. This national survey was designed to identify the prevalence and severity of these symptoms in vascular surgeons. METHODS: A survey was emailed to the 2910 members of the Society for Vascular Surgery. Physical pain was evaluated based on body part, and type of vascular procedure performed using the Borg 0 to 10 pain scale. Wellness questions were also queried. RESULTS: A total of 775 of Society for Vascular Surgery members responded, with a 26.6% response rate. Retirees were excluded from the study (n = 39). Among those actively working (n = 736), surgeons have been practicing surgery, on average, for 17.2 ± 11.6 years, with a mean age of 51.4 ± 10.9 years, and 83.6% are male. After a full day of open surgery, the majority of the responding vascular surgeons are in a moderately strong amount of pain (mean score, 4.4 ± 2.3). After a full day of endovascular procedures, most vascular surgeons are in a moderately strong amount of pain (mean score, 3.9 ± 2.4). Pain after open surgery is greatest in the neck, and after endovascular surgery pain is highest in the lower back. Surgeons performing endovenous procedures demonstrated the lowest pain scores (2.0 ± 2.0). In total, 36.9% (242/655, 81 missing responses) have sought medical care for work-related pain, with 8.3% (61/736) taking time away from the operating room. Of those, 26.2% (193/736) report pain severe enough that it interferes with sleep. Seventy-two (10%) required surgery or other significant medical procedures. Of the 39 retirees, 26% ended their careers owing to physical disabilities from work-related pain. Out of the entire cohort, 52.7% (334/633,103 missing responses) feel that physical discomfort will affect the longevity of their careers. Additionally, we found that high work-related physical discomfort is significantly associated with burnout (burnout vs no burnout; P < .0001). CONCLUSIONS: Our study shows that the majority of practicing vascular surgeons responding to the survey are in pain after a day of operating. Addressing work-related pain serves to improve the lives and careers of vascular surgeons and enhance surgical longevity.

OBJECTIVE: The objective of this study was to estimate the ergonomic postural risk (EPR) for musculoskeletal posture of vascular surgeons performing open and endovascular procedure types and with various adjunctive equipment using wearable inertial measurement unit (IMU) sensors. The hypothesis was that EPR will increase with increased physical and mental demand as well as with procedural complexity. METHODS: A prospective, observational study was conducted at a large, quaternary academic hospital located at two sites. Sixteen vascular surgeons (13 male) participated in the study. Participants completed a presurgery and postsurgery survey consisting of a body part discomfort scale and a modified NASA-Task Load Index. Participants wore IMU sensors on the head and upper body to measure EPR during open and endovascular procedures. RESULTS: Vascular surgeons have increased EPR scores of the neck as measured by the IMUs and increased lower back pain when performing open surgery compared with non-open surgery (P < .05). Open procedures were rated as more physically demanding. The use of loupes resulted in increased EPR scores for the neck and torso (P < .05), and they were significantly associated with higher levels of lower back pain during procedures (P < .05) as well as with higher levels of physical demand (P < .05). The use of headlights also resulted in increased subjectively measured levels of physical demand and lower back pain. In comparing survey responses with IMU data, surveyed physical demand was strongly and significantly correlated with the neck (r = 0.61; P < .0001) and torso (r = 0.59; P < .0001) EPR scores. The use of lead aprons did not affect EPR or most surveyed measures of workload but resulted in significantly higher levels of distraction (P < .01). The data presented highlight the potential of using wearable sensors to measure the EPR of surgeons during vascular surgical procedures. CONCLUSIONS: Vascular surgeons should be aware of EPR during the performance of their duties. Procedure type and surgical adjuncts can alter EPR significantly.

BACKGROUND: Public focus on health care spending has increased attention on variation in practice patterns and overutilization of high-cost services. Mainstream news reports have revealed that a small number of providers account for a disproportionate amount of total Medicare payments. Here, we explore variation in Medicare payments among vascular surgeons and compare practice patterns of the most highly reimbursed surgeons to the rest of the workforce. METHODS: 2016 Medicare Provider Utilization Data were queried to identify procedure, charge, and payment data to vascular surgeons, identified by National Provider Identification taxonomy. Commonly performed services (>10/year) were stratified into categories (endovascular, open surgery, varicose vein, evaluation and management, etc.). Practice patterns of vascular surgeons comprising the top 1% Medicare payments (n = 31) were compared with the remainder of the workforce (n = 3,104). RESULTS: In 2016, Medicare payments to vascular surgeons totaled $589 M. 31 vascular surgeons-1% of the workforce-received $91 million (15% of total payments). Practice patterns of the 1% differed significantly from the remainder of vascular surgeons (P < 0.05), with endovascular procedures accounting for 85% of their reimbursement. Specifically, the 1% received 49% of total Medicare payments for atherectomy ($121 M), 98% of which were performed in the office setting. CONCLUSIONS: One percentage of vascular surgeons receive an inordinate amount of total Medicare payments to the specialty. This discrepancy is due to variations in volume, utilization, and site of service. Disproportionate use of outpatient atherectomy in a small number of providers, for example, raises concerns regarding appropriateness and overutilization. Given current scrutiny over health care spending, these findings should prompt serious discussion regarding the utility of personal and societal self-regulation.

BACKGROUND: Clinical decisions regarding the utility of carotid revascularization are informed by randomized controlled trial (RCT) results. However, RCTs generally require participating surgeons to meet strict inclusion criteria with respect to procedure volume. The purpose of this study was to compare annual surgeon volume for carotid endarterectomy (CEA) in contemporary practice to RCT inclusion thresholds. METHODS: Surgeon volume thresholds were identified in 17 RCTs evaluating the efficacy of CEA (1986-present, n = 17). Contemporary annual surgeon volumes (2012-2017) were identified by aggregating data from the Medicare Provider Utilization Database and Healthcare Cost and Utilization Project Network (HCUP), and compared to RCT inclusion thresholds. Further comparisons were performed over time, and across specialties (i.e., vascular surgeon vs. other, based on board certification associated with provider NPI). RESULTS: Minimal surgeon volume in 17 RCTs ranged from 10 to 25 CEA annually when specific case volumes were required. From 2012 to 2017, CEA incidence in Medicare beneficiaries declined from 68,608 to 56,004 and became increasingly consolidated in fewer providers (7,331 vs. 6,626). However, in 2016 only 26.2% of surgeons performing CEA in Medicare beneficiaries would have met the least stringent volume requirement (10 CEA/year). Only 6.5% of surgeons performing CEA met the most stringent RCT volume threshold (25 cases/year) during the same time period. In 2017, 819 vascular surgeons (25.5% of those certified in the specialty) performed >10 CEA in Medicare beneficiaries. CONCLUSIONS: The majority of surgeons performing CEA do not meet the annual volume thresholds required for participation in the RCTs that have evaluated the efficacy of carotid revascularization. Given the established volume-outcome relationship in CEA, the disparity between surgeon experience in the context of RCTs versus contemporary practice is concerning. These findings have potential implications for informed decision-making, hospital privileging, and regionalization of care.

Quantifying the workload and postural demand on vascular surgeons provides valuable information on the physical and cognitive factors that predispose vascular surgeons to musculoskeletal pain and disorders. The aim of this study was to quantify the postural demand, workload, and discomfort experienced by vascular surgeons and to identify procedural factors that influence surgical workload. Both objective (wearable posture sensors) and subjective (surveys) assessment tools were used to evaluate intraoperative workload during 47 vascular surgery procedures. Results demonstrate unfavorable neck and low back postures as well as high pain scores for those body segments. Additionally, workload from subjective surveys increased significantly as a function of operative duration, and mental workload was high across all procedure types. Neck postural risk exposure and physical demand were among the variables that increased with surgical duration, procedure type, and loupes used by the surgeons. Correlations among postural angles and pain scores showed consistency between the objective assessment and the subjective surveys for neck and trunk. The authors believe that the results of this study highlight the need for developing mitigating measures such as ergonomic interventions for vascular surgery.

INTRODUCTION: Physician burnout has been linked to medical errors, decreased patient satisfaction, and decreased career longevity. In light of the increasing prevalence of cardiovascular disease, vascular surgeon burnout presents a legitimate public health concern owing to the impact on the adequacy of the vascular surgery workforce. The aims of this study were to define the prevalence of burnout among practicing vascular surgeons and identify factors that contribute to burnout to facilitate future Society for Vascular Surgery (SVS) initiatives to mitigate this crisis. METHODS: In 2018, active SVS members were surveyed electronically and confidentially using the Maslach Burnout Inventory. The survey was tailored to explore specialty-specific issues, and to capture demographic and practice-related characteristics. Emotional exhaustion (EE) and depersonalization (DP) were analyzed as dimensions of burnout. Consistent with convention, surgeons with a high score on the DP and/or EE subscales of the Maslach Burnout Inventory were considered to have at least one manifestation of professional burnout. Risk factors associated with symptoms of burnout were identified using bivariate analyses (χ2, Kruskal-Wallis). Multivariate logistic regression models were developed to identify independent risk factors for burnout. RESULTS: Of 2905 active SVS members, 960 responded to the survey (34% participation rate). After excluding retired surgeons and incomplete submissions, responses from 872 practicing vascular surgeons were analyzed. The mean age was 49.7 ± 11.0 years; the majority of respondents (81%) were male. Primary practice settings were academic (40%), community practice (41%), veteran's hospital (3.3%), active military practice (1.5%), or other. Years in practice averaged 15.7 ± 11.7. Overall, 41% of respondents had at least one symptoms of burnout (ie, high EE and/or high DP), 37% endorsed symptoms of depression in the past month, and 8% indicated they had considered suicide in the last 12 months. In unadjusted analysis, factors significantly associated with burnout (P < .05) included clinical work hours, on-call frequency, electronic medical record and documentation requirements, work-home conflict, and work-related physical pain. On multivariate analysis, age, work-related physical pain and work-home conflict were independent predictors for burnout. CONCLUSIONS: Symptoms of burnout and depression are common among vascular surgeons. Advancing age, work-related physical pain, and work-home conflict are independent predictors for burnout among vascular surgeons. Efforts to promote vascular surgeon well-being must address specialty-specific challenges, including the high prevalence of work-home conflict and occupational factors that contribute to work-related pain.

Prior studies suggest high prevalence of intracranial aneurysms (IA) in patients with infrarenal abdominal aortic aneurysms (AAA). We reviewed our multicenter experience in clinical detection/treatment of IAs in AAA patients and estimated the risk of IA in patients with AAA relative to patients without AAA. We reviewed cases of vascular surgery infrarenal AAA repairs at three Mayo Clinic sites from January 1998 to December 2018. Concurrent controls were randomly matched in a 1:1 ratio by age, sex, smoking history, and head imaging characteristics. Conditional logistic regression was used to calculate odds ratios. We reviewed 2,300 infrarenal AAA repairs. Mean size of AAA at repair was 56.9 ± 11.4 mm; mean age at repair, 75.8 ± 8.0 years. 87.5% of the cases ( n = 2014) were men. Head imaging was available in 421 patients. Thirty-seven patients were found to have 45 IAs for a prevalence of 8.8%. Mean size of IA was 4.6 ± 3.5 mm; mean age at IA detection, 72.0 ± 10.8 years. Thirty (81%) out of 37 patients were men. Six patients underwent treatment for IA: four for ruptured IAs and two for unruptured IAs. All were diagnosed before AAA repair. Treatment included five clippings and one coil-assisted stenting. Time from IA diagnosis to AAA repair was 16.4 ± 11.0 years. Two of these patients presented with ruptured AAA, one with successful repair and a second one that resulted in death. Odds of IA were higher for patients with AAA versus those without AAA (8.8% [37/421] vs. 3.1% [13/421]; OR 3.18; 95% confidence interval, 1.62-6.27, p < 0.001). Co-prevalence of IA among patients with AAA was 8.8% and is more than three times the rate seen in patients without AAA. All IAs were diagnosed prior to AAA repair. Surveillance for AAA after IA treatment could have prevented two AAA ruptures and one death.
RESUMO
BACKGROUND: The adverse gender disparities for women after open abdominal aortic aneurysm (AAA) repair have been well documented. The purpose of this study is to review whether these disparities extend to elective endovascular aneurysm repair (EVAR). METHODS: Nonruptured, elective AAA was identified from the American College of Surgeons' National Quality Improvement Program (NSQIP) Targeted Participant Use File for EVAR from 2012 to 2017. The primary outcome was mortality. Secondary outcomes included lower extremity ischemia requiring intervention (LEIRI) and prolonged operative time (>120 min). Multivariable logistic regression models were used to assess the risk of mortality, LEIRI, and prolonged operative time among women compared with men. RESULTS: There were 14,019 EVAR procedures captured. A total of 3,367 were included for analysis after limiting to nonruptured, elective cases for diagnosis of AAA with a Current Procedural Terminology procedure code for EVAR. Of those, 2,764 (82.1%) were performed in men and 603 (17.9%) in women. Female patients were older (median [interquartile range (IQR)] 77 years [70-82] versus 74 years [68-80], P < 0.001), more likely to smoke (35.5% versus 29.6%, P = 0.005), and less likely to have diabetes (12.4% versus 17.8%, P = 0.001). Women had slightly smaller AAA size (median [IQR] 5.4 cm [5.0-5.9] versus 5.5 cm [5.1-6.0], P < 0.001) and were more likely to have prior abdominal operations (35.3% versus 23.1%, P < 0.001). The operative time was longer among women (median 114 min. [85-150] versus 105 min. [82-140], P < 0.001). Postoperatively, mortality was higher in female patients (1.8% versus 0.9%, P = 0.036), LEIRI occurred in higher proportion among female patients (2.7% versus 1.2%, P = 0.009), and their hospital stay was also longer (median 2 days [1-3] versus 1 day [1-2] days, P < 0.001). On multivariable logistic regression analysis, hematocrit level <30 vol% versus ≥30 vol% (odds ratio (OR) 5.5, 95% confidence interval (CI) 2.1-14.5, P < 0.001) was associated with increased mortality. Although not statistically significant, there was also evidence that the odds of mortality were also greater among women (OR 2.0, 95% CI 0.98-4.2, P = 0.06). LEIRI was more likely among women (OR 2.1, 95% CI 1.2-3.9, P = 0.015) and patients with a smoking history (OR 1.8, 95% CI 1.0-3.2, P = 0.044). Finally, odds of prolonged operative time were higher among women (OR 1.4, 95% CI 1.2-1.7, P < 0.001) and patients with chronic obstructive pulmonary disease (OR 1.2, 95% CI 1.0-1.5, P = 0.033) or partial/total dependent functional status (OR 2.2, 95% CI 1.3-3.7, P = 0.003). CONCLUSIONS: Although EVAR has improved overall surgical AAA outcomes, the NSQIP data in elective EVAR demonstrate continued sex disparities in morbidity and mortality after AAA surgical repair to the detriment of female patients.

OBJECTIVE: Endovascular aneurysm repair (EVAR) can result in high radiation dose to patients and operators. This prospective randomized study aimed to assess whether patient radiation dose sustained during EVAR could be decreased by predominantly using digital fluoroscopy (DF) vs the standard technique using digital subtraction angiography (DSA). METHODS: Between February 2011 and June 2017, patients with EVAR of infrarenal abdominal aortic aneurysms were prospectively enrolled and randomly assigned to a standard treatment DSA cohort or a DF cohort in which two or fewer DSA acquisitions were allowed for confirmatory imaging. Primary end points included dose-area product (DAP) and cumulative air kerma. Secondary end points included technical success and conversion to DSA standard treatment (if DF was inadequate for visualization). RESULTS: For all 43 patients enrolled (26 in the DF cohort, 17 in the DSA cohort), technical success was 100%. Of the 26 DF patients, 5 (19%) required conversion to the DSA cohort. In an intention-to-treat analysis, mean DAP was significantly lower in the DF cohort than in the DSA cohort (132 vs 174 Gy·cm2; P = .04). When patients were separated by number of DSA acquisitions (two or fewer vs three or more), mean DAP decreased 41% (109 vs 185 Gy·cm2; P = .005) and cumulative air kerma decreased 40% (578 vs 964 mGy; P = .004). CONCLUSIONS: In most patients (81%), DF or limited DSA was adequate for visualization during EVAR. In both intention-to-treat DF and limited-DSA cohorts, mean DAP was significantly decreased. If image quality allows, a DF-only or limited-DSA approach to EVAR decreases radiation dose.

BACKGROUND: Surgeons are at high risk of developing musculoskeletal disorders. STUDY DESIGN: This study was designed to identify risk factors and assess intraoperative physical stressors using subjective and objective measures, including type of procedure and equipment used. Wearable sensors and pre- and postoperation surveys were analyzed. RESULTS: Data from 116 cases (34 male and 19 female surgeons) were collected across surgical specialties. Surgeons reported increased pain in the neck, upper, and lower back both during and after operations. High-stress intraoperative postures were also revealed by the real-time measurement in the neck and back. Surgical duration also impacted physical pain and fatigue. Open procedures had more stressful physical postures than laparoscopic procedures. Loupe usage negatively impacted neck postures. CONCLUSIONS: This study highlights the fact that musculoskeletal disorders are common in surgeons and characterizes surgeons' intraoperative posture as well as surgeon pain and fatigue across specialties. Defining intraoperative ergonomic risk factors is of paramount importance to protect the well-being of the surgical workforce.
