RESUMEN
OBJECTIVE: Prior research on median arcuate ligament syndrome has been limited to institutional case series, making the optimal approach to median arcuate ligament release (MALR) and resulting outcomes unclear. In the present study, we compared the outcomes of different approaches to MALR and determined the predictors of long-term treatment failure. METHODS: The Vascular Low Frequency Disease Consortium is an international, multi-institutional research consortium. Data on open, laparoscopic, and robotic MALR performed from 2000 to 2020 were gathered. The primary outcome was treatment failure, defined as no improvement in median arcuate ligament syndrome symptoms after MALR or symptom recurrence between MALR and the last clinical follow-up. RESULTS: For 516 patients treated at 24 institutions, open, laparoscopic, and robotic MALR had been performed in 227 (44.0%), 235 (45.5%), and 54 (10.5%) patients, respectively. Perioperative complications (ileus, cardiac, and wound complications; readmissions; unplanned procedures) occurred in 19.2% (open, 30.0%; laparoscopic, 8.9%; robotic, 18.5%; P < .001). The median follow-up was 1.59 years (interquartile range, 0.38-4.35 years). For the 488 patients with follow-up data available, 287 (58.8%) had had full relief, 119 (24.4%) had had partial relief, and 82 (16.8%) had derived no benefit from MALR. The 1- and 3-year freedom from treatment failure for the overall cohort was 63.8% (95% confidence interval [CI], 59.0%-68.3%) and 51.9% (95% CI, 46.1%-57.3%), respectively. The factors associated with an increased hazard of treatment failure on multivariable analysis included robotic MALR (hazard ratio [HR], 1.73; 95% CI, 1.16-2.59; P = .007), a history of gastroparesis (HR, 1.83; 95% CI, 1.09-3.09; P = .023), abdominal cancer (HR, 10.3; 95% CI, 3.06-34.6; P < .001), dysphagia and/or odynophagia (HR, 2.44; 95% CI, 1.27-4.69; P = .008), no relief from a celiac plexus block (HR, 2.18; 95% CI, 1.00-4.72; P = .049), and an increasing number of preoperative pain locations (HR, 1.12 per location; 95% CI, 1.00-1.25; P = .042). The factors associated with a lower hazard included increasing age (HR, 0.99 per increasing year; 95% CI, 0.98-1.0; P = .012) and an increasing number of preoperative diagnostic gastrointestinal studies (HR, 0.84 per study; 95% CI, 0.74-0.96; P = .012) Open and laparoscopic MALR resulted in similar long-term freedom from treatment failure. No radiographic parameters were associated with differences in treatment failure. CONCLUSIONS: No difference was found in long-term failure after open vs laparoscopic MALR; however, open release was associated with higher perioperative morbidity. These results support the use of a preoperative celiac plexus block to aid in patient selection. Operative candidates for MALR should be counseled regarding the factors associated with treatment failure and the relatively high overall rate of treatment failure.

BACKGROUND: Extracranial carotid artery aneurysms (ECAA) are rare. Open surgery has traditionally been the treatment of choice, and endovascular management has recently been increasingly described. However, operative guidelines have not been defined. METHODS: A systematic review following PRISMA guidelines was performed to identify articles related to the symptoms, treatments, and outcomes of ECAAs. Included studies were further evaluated to identify distribution of treatment strategy based on anatomical location by Attigah classification (Type I-V) and aneurysmal type (true versus pseudoaneurysm). RESULTS: Twenty-eight retrospective reviews were included. A total of 906 patients (63% male) with 959 ECAAS were identified. The most common presenting symptoms included neck mass (45%) and neurological deficits (26%), while 218 (23%) were asymptomatic. True aneurysms accounted for 52% and pseudoaneurysms for 45% of cases. Of the 959 ECAAs, 750 were treated with open surgery, 85 with an endovascular procedure, and 124 conservatively. Perioperative complications of open surgery included cranial nerve injuries (CNI) in 9% (68), strokes in 4% (27), and death in 2% (18) of cases. There were no CNI, perioperative stroke, or perioperative mortality associated with 85 endovascular procedures; however, there was 1 case of restenosis (1%). Of the 124 patients treated conservatively, 3% (4) died as a result of the aneurysm. Twenty-two of 28 studies (688 ECAAs) reported anatomical location according to Attigah classification. The distribution of ECAAs were Type I (296/688; 43%), Type II (19/688; 3%), Type III (195/688; 28%), Type IV (76/688: 11%), and Type V (102/688; 15%). Eleven of 28 studies (241 ECAAs) reported treatment choice according to Attigah classification and revealed that the majority of Type I (82%), Type II (81%), Type III (91%), and Type IV (100%) ECAAs were treated via open surgery, while Type V ECAAs were evenly treated by open surgery and endovascular surgery. Twenty-three of 28 studies (780 ECAAs) reported treatment choice stratified by aneurysmal type. Of 417 true ECAAs, 88% were treated open surgically, 4% were treated endovascularly, and 8% were treated conservatively. Of 357 pseudoaneurysms, 67% were treated open surgically, 14% were treated endovascularly, and 19% were treated conservatively. CONCLUSIONS: Most reported patients with ECAAs are symptomatic. Type I and III account for more than two-thirds of ECAAs, while true aneurysms account for roughly half. The vast majority of ECAAs have been treated surgically with results comparable to reoperative carotid endarterectomy. In selected patients, endovascular treatment has been very successful with no reported morbidity or mortality.

BACKGROUND: Aortic coarctation in the adult is usually associated with chronic systemic hypertension, which leads to the sequelae of congestive heart failure, vascular dysfunction and decreased lifespan. Open and endovascular treatment modalities both provide excellent procedural outcomes with minimal mortality and morbidity, but a structured algorithm for workup and periprocedural decision making is not well established. We outline our heart team decision making approach along with our institution's experience treating this condition. METHODS: We retrospectively reviewed twenty-four consecutive adult patients treated for aortic coarctation since 2010 at a single center. Outcomes of interest included mortality, treatment approach, device used and post-procedure hypertension status. We describe our protocol for work-up and intervention decision making. We explain our rationale for recommending treatment and the approach, open or endovascular, using existing literature and our experience. RESULTS: Procedural success rate was 100%, and there were no 30-day, one-year or five-year mortalities, whether the approach was open or endovascular. At last contact, 32% of patients were normotensive and no longer taking blood pressure medications. Several patients presented with complex problems as a result of commonly described complications of prior open or endovascular repair, and we describe our approach to the management of these difficult cases. CONCLUSIONS: Even at a high-volume heart and vascular hospital, aortic coarctation is an uncommon presentation in adult patients. Our experience suggests that excellent outcomes are obtained by discussing each patient among a multidisciplinary heart team and developing a work-up and treatment protocol to guide selection of interventional modality.
RESUMEN
BACKGROUND: Left subclavian artery (LSA) revascularization has been recommended for patients undergoing elective thoracic endovascular aortic repair (TEVAR) with a proximal zone 2 landing requiring coverage of the LSA. The clinical standard of care remains surgical LSA revascularization. However, recently, the feasibility of using branched endografts has been demonstrated. We compared the perioperative and mid-term outcomes of these approaches. METHODS: We performed a retrospective review of consecutive patients who underwent TEVAR with a proximal zone 2 landing at a single center from 2014 to 2020. The patients were divided into cohorts for comparison: those who underwent surgical revascularization (SR-TEVAR group) and those who underwent thoracic branched endografting with an investigational device (TBE group). Those patients who did not undergo LSA revascularization were excluded. Perioperative outcomes, including procedural success, death, stroke, limb ischemia, and length of stay, were compared. Kaplan-Meier survival curves were compared using the log-rank test. The cumulative incidence of device-related endoleak (types I and III) and device-related reintervention, accounting for death as a competing hazard, were compared using the Fine-Gray test. RESULTS: A total of 55 patients were included: 31 (56%) in the SR-TEVAR group and 24 (44%) in the TBE group. The preoperative demographics and comorbidities were similar between the two groups. Procedural success was 100% in both cohorts, with no periprocedural strokes or left upper extremity ischemic events. One operative or 30-day death (TBE, 4.2%; vs SR-TEVAR, 3.2%; P = .99) occurred in each cohort. The total operative time (TBE, 203 ± 79 minutes; vs SR-TEVAR, 250 ± 79 minutes; P = .03) and total length of stay (TBE, 5.2 ± 3.6 days; vs SR-TEVAR, 9.9 ± 7.2 minutes; P = .004) were both significantly shorter in the TBE group. No difference was found in mid-term survival (log-rank test, P = .50) nor the cumulative incidence of device-related endoleak (Fine-Gray test, P = .51) or reintervention (Fine-Gray test, P = .72). No occlusions of the TBE graft or surgical bypass or transpositions had occurred after a mean follow-up of 28 ± 16 and 34 ± 24 months, respectively. CONCLUSIONS: TBE can be performed with procedural success rate and safety profile comparable to those of TEVAR with surgical revascularization, with a decreased total length of stay, for patients requiring proximal zone 2 coverage. The mid-term outcomes for each approach were also similar. Prospective, randomized comparisons of these techniques are warranted.

BACKGROUND: The utilisation rate of endovascular aortic aneurysm repair has increased continuously over the past 2 decades. Endovascular aortic aneurysm repair is still performed frequently in patients with an unfavourable proximal seal zone, despite the associated late complications. PURPOSE: We aimed to evaluate the mid-term durability of the GORE® EXCLUDER® AAA Endoprosthesis, featuring the C3 delivery system, in patients with a proximal neck anatomy outside the instructions for use (IFU). METHODS: A retrospective sub-analysis of the Global Registry for Endovascular Aortic Treatment including patients treated for abdominal aortic aneurysms with the GORE EXCLUDER AAA Endoprosthesis (W.L. Gore & Associates, Inc, Flagstaff, Arizona) was performed. A "challenging neck" was defined as those treated outside the IFU with an aortic neck length <15 mm and/or aortic neck angle >60°. Cox proportional analyses were used to test for time-to-event differences between those treated within and outside the IFU while accounting for covariates, specifically proximal neck length and neck angle. The main outcomes assessed were 5-year all-cause mortality, 5-year endoleak development (type I or III), and 5-year device-related reinterventions. FINDINGS: Of the 3,324 patients included in the analysis, 411 (12.4%) had a challenging neck and 2,913 (87.6%) did not. The patients in the challenging neck group were significantly older (74.9 years vs. 73.2 years, p≤0.0001) and had a significantly larger aortic aneurysm diameter at the time of the intervention than those treated within the IFU (61.2 mm vs. 56.4 mm, P< 0.0001), shorter proximal neck length (18 mm vs. 30 mm, P< 0.0001) and larger infrarenal neck angle (60.8° vs. 25.8°, P< 0.0001). In the multivariate analysis, brachial access site and challenging neck were not independent risk factors; increased age was associated with a shorter time to mortality (hazard ratio 1.051, 95% confidence interval 1.039-1.062, P< 0.0001), as was the use of tobacco (hazard ratio 1.329, 95% confidence interval 1.124-1.571, P= 0.0009). The 5-year all-cause mortality (36.2% vs. 27.5%, P= 0.002) and aorta-related mortality (3.8% vs. 1.1%, P= 0.002) were significantly higher in the challenging neck group. The risk of death within 5 years also increased significantly at 1.1% per millimetre increase in the abdominal aortic aneurysm diameter (P= 0.0005). Furthermore, the rates of type Ia endoleak development (7% vs. 1.2%, P< 0.001) and requirement for reintervention (13.3% vs. 9.7%, P< 0.001) were higher in those treated outside the IFU (challenging neck group). CONCLUSIONS: Treatment with the Excluder AAA Endograft outside the IFU was associated with higher 5-year mortality values, increased type Ia endoleak development rates, and a greater need for reintervention compared with treatment within the IFU. This reiterates that fenestrated and open treatments should be strongly considered in cases with aortic neck anatomies outside the IFU. Infrarenal endovascular intervention outside the IFU should only be used when there is no alternative, with meticulous procedural planning and intervention to promote satisfactory outcomes.

BACKGROUND: The U.S. healthcare system is undergoing a broad transformation from the traditional fee-for-service model to value-based payments. The changes introduced by the Medicare Quality Payment Program, including the establishment of Alternative Payment Models, ensure that the practice of vascular surgery is likely to face significant reimbursement changes as payments transition to favor these models. The Society for Vascular Surgery Alternative Payment Model taskforce was formed to explore the opportunities to develop a physician-focused payment model that will allow vascular surgeons to continue to deliver the complex care required for peripheral arterial disease (PAD). METHODS: A financial analysis was performed based on Medicare beneficiaries who had undergone qualifying index procedures during fiscal year 2016 through the third quarter of 2017. Index procedures were defined using a list of Healthcare Common Procedural Coding (HCPC) procedure codes that represent open and endovascular PAD interventions. Inpatient procedures were mapped to three diagnosis-related group (DRG) families consistent with PAD conditions: other vascular procedures (codes, 252-254), aortic and heart assist procedures (codes, 268, 269), and other major vascular procedures (codes, 270-272). Patients undergoing outpatient or office-based procedures were included if the claims data were inclusive of the HCPC procedure codes. Emergent procedures, patients with end-stage renal disease, and patients undergoing interventions within the 30 days preceding the index procedure were excluded. The analysis included usage of postacute care services (PACS) and 90-day postdischarge events (PDEs). PACS are defined as rehabilitation, skilled nursing facility, and home health services. PDEs included emergency department visits, observation stays, inpatient readmissions, and reinterventions. RESULTS: A total of 123,180 cases were included. Of these 123,180 cases, 82% had been performed in the outpatient setting. The Medicare expenditures for all periprocedural services provided at the index procedure (ie, professional, technical, and facility fees) were higher in the inpatient setting, with an average reimbursement per index case of $18,755, $34,600, and $25,245 for DRG codes 252 to 254, DRG codes 268 and 269, and DRG codes 270 to 272, respectively. Outpatient facility interventions had an average reimbursement of $11,458, and office-based index procedures had costs of $11,533. PACS were more commonly used after inpatient index procedures. In the inpatient setting, PACS usage and reimbursement were 58.6% ($5338), 57.2% ($4192), and 55.9% ($5275) for DRG codes 252 to 254, DRG codes 268 and 269, and DRG codes 270 to 272, respectively. Outpatient facility cases required PACS for 13.7% of cases (average cost, $1352), and office-based procedures required PACS in 15% of cases (average cost, $1467). The 90-day PDEs were frequent across all sites of service (range, 38.9%-50.2%) and carried significant costs. Readmission was associated with the highest average PDE expenditure (range, $13,950-$18.934). The average readmission Medicare reimbursement exceeded that of the index procedures performed in the outpatient setting. CONCLUSIONS: The cost of PAD interventions extends beyond the index procedure and includes relevant spending during the long postoperative period. Despite the analysis challenges related to the breadth of vascular procedures and the site of service variability, the data identified potential cost-saving opportunities in the management of costly PDEs. Because of the vulnerability of the PAD patient population, alternative payment modeling using a bundled value-based approach will require reallocation of resources to provide longitudinal patient care extending beyond the initial intervention.

Implementation of telemedicine for patient encounters optimizes personal safety and allows for continuity of patient care. Embracing telehealth reduces the use of personal protective equipment and other resources consumed during in-person visits. The use of telehealth has increased to historic levels in response to the coronavirus disease 2019 (COVID-19) pandemic. Telehealth may be a key modality to fight against COVID-19, allowing us to take care of patients, conserve personal protective equipment, and protect health care workers all while minimizing the risk of viral spread. We must not neglect vascular health issues while the coronavirus pandemic continues to flood many hospitals and keep people confined to their homes. Patients are not immune to diseases and illnesses such as stroke, critical limb ischemia, and deep vein thrombosis while being confined to their homes and afraid to visit hospitals. Emerging from the COVID-19 crisis, incorporating telemedicine into routine medical care is transformative. By leveraging digital technology, the authors discuss their experience with the implementation, workflow, coding, and reimbursement issues of telehealth during the COVID-19 era.

BACKGROUND: Arterial access and device delivery in endovascular aortic repair (EVAR) and thoracic endovascular aortic repair (TEVAR) have evolved from open femoral or iliac artery exposure to selective percutaneous arterial access. Although regional application of percutaneous access for these 2 procedures varies widely, the use of this technique continues to increase. Currently, differences in the use of percutaneous access between EVAR and TEVAR have not been well explored. The Gore Global Registry for Endovascular Aortic Treatment (GREAT) registry collected relevant data for evaluation of these issues and the comparative results between open and percutaneous approaches in regard to complication rates and length of stay (LOS). METHODS: This study was performed via a retrospective review of patients from the GREAT registry (Clinicaltrials.gov no. NCT01658787). The primary variable of this study was access site complications including postoperative hematoma, vessel dissection, and pseudoaneurysm. Patients were categorized by abdominal (EVAR) and thoracic (TEVAR) aortic procedures using percutaneous-only, cutdown-only, and combined vascular access techniques for a total of 6 groups. Standard statistical methodology was used to perform single-variable and multivariable analysis of a variety of covariates including LOS, geographical location of procedure, procedural success rate, and access sheath size. RESULTS: Of 4,781 patients from the GREAT registry, 3,837 (80.3%) underwent EVAR and 944 (19.7%) underwent TEVAR with percutaneous-only access techniques being used in 2,017 (42.2%) and cutdown-only in 2,446 (51.2%). There was variable application of percutaneous access by geographic region with Australia and New Zealand using this technique more frequently and Brazil using percutaneous access the least. No significant difference in the rate of access site complications was detected between the 6 groups of patients in the study; however, significantly lower rates of access site complications were associated with percutaneous-only compared with both cutdown-only and combined techniques (P = 0.03). In addition, associated with significantly higher rates of access site complications was longer LOS (P < 0.01). Average LOS was 5.2 days and was higher in the TEVAR group (10.1 days) than that in EVAR (4.0 days, P < 0.05). Increased sheath size does not appear to increase the risk of access site complication. CONCLUSIONS: There was no significant difference found in the complication rate between percutaneous and cutdown access techniques. This analysis demonstrates that percutaneous-only access is safe, has low complication rates, and has lower LOS compared with open access or combined access techniques.

The Society for Vascular Surgery Alternative Payment Model (APM) Taskforce document explores the drivers and implications for developing objective value-based reimbursement plans for the care of patients with peripheral arterial disease (PAD). The APM is a payment approach that highlights high-quality and cost-efficient care and is a financially incentivized pathway for participation in the Quality Payment Program, which aims to replace the traditional fee-for-service payment method. At present, the participation of vascular specialists in APMs is hampered owing to the absence of dedicated models. The increasing prevalence of PAD diagnosis, technological advances in therapeutic devices, and the increasing cost of care of the affected patients have financial consequences on care delivery models and population health. The document summarizes the existing measurement methods of cost, care processes, and outcomes using payor data, patient-reported outcomes, and registry participation. The document also evaluates the existing challenges in the evaluation of PAD care, including intervention overuse, treatment disparities, varied clinical presentations, and the effects of multiple comorbid conditions on the cost potentially attributable to the vascular interventionalist. Medicare reimbursement data analysis also confirmed the prolonged need for additional healthcare services after vascular interventions. The Society for Vascular Surgery proposes that a PAD APM should provide patients with comprehensive care using a longitudinal approach with integration of multiple key medical and surgical services. It should maintain appropriate access to diagnostic and therapeutic advancements and eliminate unnecessary interventions. It should also decrease the variability in care but must also consider the varying complexity of the presenting PAD conditions. Enhanced quality of care and physician innovation should be rewarded. In addition, provisions should be present within an APM for high-risk patients who carry the risk of exclusion from care because of the naturally associated high costs. Although the document demonstrates clear opportunities for quality improvement and cost savings in PAD care, continued PAD APM development requires the assessment of more granular data for accurate risk adjustment, in addition to largescale testing before public release. Collaboration between payors and physician specialty societies remains key.

BACKGROUND: Abdominal aortic aneurysms (AAAs) are more common in men. However, women have been shown to have more short- and long-term adverse outcomes after endovascular aneurysm repair. This disparity is thought to be multifactorial, including anatomical differences, hormonal differences, older age of presentation, and a greater degree of preoperative comorbidities. METHODS: A retrospective analysis that included data for 3,758 patients from the Global Registry for Endovascular Aortic Treatment (GREAT) was conducted. Patients were recruited into GREAT between August 2010 and October 2016 and received the Gore Excluder stent graft for infrarenal AAAs repair. Cox multivariate regression analyses were performed to analyze any reintervention and device-related intervention rates. RESULTS: Of the 3,758 patients, 3,220 were male (mean age 73 years) and 538 were female (mean age 75 years). Women had higher prevalence rates of chronic obstructive pulmonary disease (P < 0.0001) and renal insufficiency (P = 0.03), whereas men had higher rates of cardiovascular comorbidities. The AAAs in women were smaller in diameter with shorter and more angulated necks. Women did not experience a significantly higher rate of endoleaks but did exhibit higher reintervention rates, including reintervention for device-related issues. In terms of mortality, aorta-related mortality was most prevalent within the first 30 days after procedure in both sexes. CONCLUSIONS: Women were treated at an older age and had a more hostile aneurysmal anatomy. Although the mortality rates were lower in women, they had significantly higher rates of reintervention, and thus higher morbidity rates after endovascular aneurysm repair.

OBJECTIVE: Spinal cord ischemia (SCI) is a dreaded complication of thoracic endovascular aortic repair (TEVAR). There are limited national data describing the incidence and influence of in-hospital SCI recovery on survival. Moreover, no robust preoperative SCI risk assessment models currently exist. The purpose of this analysis was to analyze the Vascular Quality Initiative to determine the national incidence, survival association, and preoperative predictors of SCI after TEVAR. METHODS: All Vascular Quality Initiative TEVAR procedures (June 2014-June 2019) were reviewed. The primary end point was development of in-hospital SCI, defined as any new neurologic deficit or paralysis not attributable to intracranial disease. Secondary end points were disease-specific SCI rates and long-term out-of-hospital survival. Functional outcomes (transient vs permanent SCI) were independently determined by treating physicians. Kaplan-Meier analysis and Cox proportional hazards methodology were used to assess the association of SCI with survival. A logistic regression model of candidate preoperative SCI predictors was created, and bootstrapped backward elimination (retaining predictors with ≥50% selection frequency) was used for model reduction. Model fit and performance statistics were validated by adjustment for Efron's optimism. RESULTS: The overall rate of SCI was 3.7% (n = 422/11,473; transient, 1.6% [n = 179]; permanent, 2.1% [n = 243]). Patients who developed any SCI had significantly lower Kaplan-Meier survival estimate compared with those without SCI (1-year survival: SCI, 65%; no SCI, 87%; P < .0001), and patients with permanent SCI had notably worse survival than patients with transient SCI (1-year survival: permanent SCI, 54%; transient SCI, 80%; P < .0001). Disease-specific incidence of any SCI was as follows: aneurysm, 3.4%; dissection, 5.3%; aneurysm from dissection, 4.1%; trauma, 1.1%; penetrating ulceration, 2.4%; intramural hematoma, 5.7%; penetrating ulceration and intramural hematoma, 4.3%; and aortic thrombus, 4.8%. Several factors were selected on multivariable analysis as the most robust preoperative predictors of any SCI, including distal landing zone 5 to zone 10, nonelective case, creatinine concentration >1.38 mg/dL, smoking history, American Society of Anesthesiologists class, adjunctive procedure, nonwhite race, and preoperative hypertension (area under the curve = 0.72; Nagelkerke R2 = 0.06). CONCLUSIONS: SCI is a devastating complication after TEVAR that is associated with worse overall survival, particularly when no functional recovery occurs by hospital discharge. Disease-specific, real-world benchmarks for SCI rates are provided that may inform quality initiatives focused on reducing this complication. Importantly, this analysis is the first description of a preoperative prediction model derived from national data for determining SCI risk after TEVAR. These predictors should be used to identify high-risk patients to balance the risk of SCI and its associated increased short-term mortality with the risk of the underlying disease. Furthermore, all available adjunctive measures should be implemented in these high-risk patients to reduce risk of SCI.

BACKGROUND: Several vascular surgical procedures, including repair of abdominal aortic aneurysms (AAAs), show poorer outcomes for women than for men. We evaluated the impact of sex-based demographic differences on survival after endovascular aneurysm repair (EVAR). METHODS: We reviewed EVARs performed at our institution between 2003 and 2009 and assessed aortic neck variables (length, diameter, angulation, and calcification), iliac artery variables (length, tortuosity, angulation, and calcification), and AAA diameter. Cox proportional hazards models were used to examine the association between sex and 5-year mortality while adjusting for patients' demographics, comorbidities, anatomic variables, and AAA parameters. The final model adjusted for sex, age, body mass index, hypertension, iliac artery length, and aortic neck length. RESULTS: Of 336 patients, 278 were male (mean age, 73 years) and 58 were female (mean age, 77 years; P = .0005). Men had more coronary artery bypass grafts (79 vs 8; P = .02) and percutaneous coronary interventions (52 vs 4; P = .03) than women did. Significant differences between the sexes was seen for aortic neck angle, diameter, and length and for iliac artery diameter and length. Men (44%) were more likely than women (22%; P = .0002) to have EVAR performed within the device guidelines. Five-year survival was 73% in men and 49% in women. Multivariable analysis showed that female sex, increase in age, low body mass index (<25 kg/m2), and aortic neck length were significantly associated with risk of 5-year mortality. CONCLUSIONS: Women presented at an older age and with a more hostile anatomy. They had reduced survival compared with men after EVAR. After controlling for comorbidities and aortic neck and iliac artery anatomy, sex remained an independent predictor for survival.

BACKGROUND: Blunt cerebrovascular injury (BCVI), although rare, is more common than previously thought and carries a substantial stroke and mortality risk. The purpose of our study was to evaluate the differences between blunt carotid artery (CA) and vertebral artery (VA) injuries, assess the stroke and death rates related to these injuries, and identify the relationship of Injury Severity Score (ISS) with stroke and mortality in BCVI. METHODS: Using a retrospective review of the trauma registry at a level I trauma center, we identified patients with BCVI. The study period began in January 2003 and ended in July 2014. Demographics, injuries reported, investigative studies performed, and outcomes data were obtained and analyzed. Radiographic images of both blunt CA and VA injuries were reviewed and graded by an independent radiologist, according to the current classification of blunt CA injuries. RESULTS: BCVI involving 114 vessels was identified in 103 patients. This population consisted of 65 males and 38 females with an average age of 45 years (15-92, range). The average ISS was 22 (4-75, range). Cervical spine fracture occurred in 80% of VA injuries (64 total patients). Injuries involved the CA in 33, the VA in 59, and both in 11. The CA group had a higher incidence of traumatic brain injury (61% vs. 46%), ISS (27 vs. 18), and stroke (24% vs. 3%), compared to the VA group. Mortality in the CA group was 30% compared to 3% in the VA group. Patients with high ISS (≥25) had increased stroke rates compared to those with lower (<25) ISS (19% vs. 6.7%). All mortalities occurred with ISS >25. Logistic regression revealed that vessel injured, ISS, and Glasgow Coma Scale (GCS) were significant risk factors for mortality. Multivariate analysis demonstrated carotid injury, and lowest GCS were independently associated with mortality. CONCLUSIONS: In this comparison of CA and VA injuries in BCVI, VA injuries were more common and more frequently found with cervical spine fractures than CA injuries. However, VA injuries had a lower incidence of CVA and mortality. A high ISS was associated with stroke and mortality while carotid injury and lowest GCS were independently associated with increased mortality.

The Hospital Privileges Practice Guideline Writing Group of the Society for Vascular Surgery is making the following five recommendations concerning guidelines for hospital privileges for vascular surgery and endovascular therapy. Advanced endovascular procedures are currently entrenched in the everyday practice of specialized vascular interventionalists, including vascular surgeons, but open vascular surgery remains uniquely essential to the specialty. First, we endorse the Residency Review Committee for Surgery recommendations regarding open and endovascular cases during vascular residency and fellowship training. Second, applicants for new hospital privileges wishing to perform vascular surgery should have completed an Accreditation Council for Graduate Medical Education-accredited vascular surgery residency or fellowship or American Osteopathic Association-accredited training program before 2020 and should obtain American Board of Surgery certification in vascular surgery or American Osteopathic Association certification within 7 years of completion of their training. Third, we recommend that applicants for renewal of hospital privileges in vascular surgery include physicians who are board certified in vascular surgery, general surgery, or cardiothoracic surgery. These physicians with an established practice in vascular surgery should participate in Maintenance of Certification programs as established by the American Board of Surgery and maintain their respective board certification. Fourth, we provide recommendations concerning guidelines for endovascular procedures for vascular surgeons and other vascular interventionalists who are applying for new or renewed hospital privileges. All physicians performing open or endovascular procedures should track outcomes using nationally validated registries, ideally by the Vascular Quality Initiative. Fifth, we endorse the Intersocietal Accreditation Commission recommendations for noninvasive vascular laboratory interpretations and examinations to become a Registered Physician in Vascular Interpretation, which is included in the requirements for board eligibility in vascular surgery, but recommend that only physicians with demonstrated clinical experience in the diagnosis and management of vascular disease be allowed to interpret these studies.

Objective Postoperative pain following lower extremity revascularization procedures is traditionally controlled with narcotic administration. However, this may not adequately control the pain and puts the patient at risk for complications from opiate use. Here we report an alternative strategy for pain management using a continuous catheter-infused local anesthetic into the operative limb. Design Retrospective case-control study. Methods Patients undergoing lower extremity revascularization procedures using continuous catheter-infused local anesthetic were compared to similar patients undergoing similar procedures during the same time period who did not receive continuous catheter-infused local anesthetic. Records were reviewed for pain scores, narcotics consumption, length of stay, need for postoperative chest X-ray, supplemental oxygen use, wound complications, and 30-day readmission. Results There were 153 patients (mean age 69.5 years) from September 2011 to December 2014 who underwent common femoral artery procedures, femoral-popliteal bypass, femoral-tibial bypass, popliteal aneurysm repair, popliteal to pedal bypass, popliteal artery thrombo-embolectomy, sapheno-popliteal venous bypass, or ilio-femoral bypass. There were no significant differences between the continuous catheter-infused local anesthetic ( n=57) and control ( n=96) groups regarding age, body mass index, cardiac history, diabetes, hypertension, and procedures performed. The continuous catheter-infused local anesthetic group showed better cumulative average pain scores, better high pain scores on postoperative days 1-3, and better average pain scores on postoperative days 2-3 ( P<0.03). The continuous catheter-infused local anesthetic group had lower median narcotics consumption on postoperative days 1-2 ( P=0.02). No differences were found in postoperative length of stay, urinary catheter use, number of postoperative chest X-rays, oxygen use, mobilization, or fever. Wound complications occurred in 8.8% of the continuous catheter-infused local anesthetic group and in 11.5% of controls (P=0.79). Readmission rates were 23% (continuous catheter-infused local anesthetic) and 21% (controls; P=0.84). Conclusion Postoperative continuous catheter-infused local anesthetic reduces pain scores and pain medication use compared to standard opiate therapy in these patients, without increasing wound complication or readmission rates. Continuous catheter-infused local anesthetic appeared to have no effect on the incidence of pulmonary complications, mobilization, or fever.

Patients undergoing endovascular repair (EVAR) of aortoiliac or iliac artery aneurysm may require sacrifice of one or both internal iliac arteries (IIAs). Until Food and Drug Administration-approved commercial grafts became available, endovascular IIA preservation was accomplished using the "sandwich" technique, but limited information is available regarding the results of this method. After obtaining institutional review board approval, we identified patients undergoing IIA preservation with the sandwich technique during EVAR at our institution. The patients have been followed prospectively since being identified to record patency rates and vascular symptoms or events. Twenty-four procedures were performed from 2011 through 2015 to treat iliac artery aneurysms. Fourteen of these procedures were done with concomitant EVAR using different endografts (Gore Excluder 11, Endologix AFX 2, Cook Zenith 1). Five were done to extend a previous EVAR that had developed a type Ib endoleak, 2 for an isolated external iliac artery aneurysm, 3 for an anastomotic aneurysm from a previous aortobiiliac graft, and 2 for isolated iliac aneurysm repair. There were 25 sandwich grafts (unilateral in 19, bilateral in 6). Contralateral embolization was performed in 5 cases. Immediate success rates were high, and patency rates were excellent at intermediate follow-up. Intraoperative type 3 endoleaks were not uncommon but usually resolved postoperatively. Endovascular IIA preservation is feasible with currently available devices using this technique. This procedure is recommended for preservation of the IIA during endovascular treatment of aortoiliac and iliac artery aneurysms when anatomy requires IIA preservation.
RESUMEN
Aneurysms of the hand are rarely encountered and more rarely reported. The least common locations of these aneurysms are the palmar and digital arteries. The etiologies of these entities are quite varied, although they usually present as a pulsatile mass. Following a thorough evaluation, including arterial anatomic imaging, they should be repaired. The reported results following repair have been good. Herein we report a girl with a spontaneous palmar artery aneurysm and its management.
