RESUMO
OBJECTIVES: The Vascular Surgery In-Training Examination (VSITE) is a yearly exam evaluating vascular trainees' knowledge base. While multiple studies have evaluated variables associated with exam outcomes, few have incorporated training program-specific metrics. The purpose of this study is to evaluate the impact of the learning environment and burnout on VSITE performance. METHODS: Data was collected from a confidential, voluntary survey administered after the 2020-2022 VSITE as part of the SECOND Trial. VSITE scores were calculated as percent correct then standardized per the American Board of Surgery. Generalized estimating equations with robust standard errors and an independent correlation structure were used to evaluate trainee and program factors associated with exam outcomes. Analyses were further stratified by integrated and independent training paradigms. RESULTS: A total of 1385 trainee responses with burnout data were collected over three years (408 in 2020, 459 in 2021, 498 in 2022). On average, 46% of responses reported at least weekly burnout symptoms. On unadjusted analysis, burnout symptoms correlated with a 14 point drop in VSITE score (95% confidence interval (CI) -24- -4, p=0.006). However, burnout was no longer significant after adjusted analysis. Instead, higher PGY level, being in a relationship, identifying as male gender with or without kids, identifying as non-Hispanic white, larger programs, and having a sense of belonging within a program were associated with higher VSITE scores. CONCLUSIONS: Despite high rates of burnout, trainees generally demonstrate resilience in gaining the medical knowledge necessary to pass the VSITE. Performance on standardized exams is associated with trainee and program characteristics, including availability of support systems and program belongingness.
RESUMO
OBJECTIVE: Implicit bias is a potential factor in the severity of examinee rating during oral examinations. Ratings may be impacted by examinee characteristics, such as gender, that are independent of examinee knowledge-base, clinical judgment or test-taking ability. The effects of examiner-examinee gender concordance in the Vascular Surgery Certifying Examination (VCE) have not been previously studied. We explored whether examiner ratings and likelihood of passing the exam were influenced by gender concordance amongst examiners and examinees. METHODS: Data collected from examinees who first attempted the VCE between 2018 and 2023 were analyzed. There were 1,005 examinees (69.3% male, 30.1% female) and 121 examiners (71.9% male, 28.1% female). Linear Mixed- Effects Models and Generalized Linear Mixed-Effects Models were used to evaluate the effects of examinee and examiner gender on VCE ratings and likelihood of passing the exam. RESULTS: Examiner-examinee gender concordance had no significant impact on examiner ratings or likelihood of passing the exam. Additionally, examinee gender alone had no significant impact on VCE rating or pass rates. Only Vascular Qualifying Exam (VQE) scores explained more than 1% of the variance in total VCE scores for the gender model (F(1,1003.5)=71.08, p-value < 0.01, R2 = 3%). VQE scores were positively related to total VCE scores. CONCLUSIONS: While implicit bias has the potential to impact examiner scoring, there is no evidence that this is the case with respect to gender in the Vascular Surgery Certifying Examination of the American Board of Surgery.
RESUMO
Importance: The ability to pursue family planning goals is integral to gender equity in any field. Procedural specialties pose occupational risks to pregnancy. As the largest procedural specialty, general surgery provides an opportunity to understand family planning, workplace support for parenthood, obstetric outcomes, and the impact of these factors on workforce well-being, gender equity, and attrition. Objective: To examine pregnancy and parenthood experiences, including mistreatment and obstetric outcomes, among a cohort of US general surgical residents. Design, Setting, and Participants: This cohort study involved a cross-sectional national survey of general surgery residents in all programs accredited by the Accreditation Council for Graduate Medical Education after the 2021 American Board of Surgery In-Training Examination. Female respondents who reported a pregnancy and male respondents whose partners were pregnant during clinical training were queried about pregnancy- and parenthood-based mistreatment, obstetric outcomes, and current well-being (burnout, thoughts of attrition, suicidality). Main Outcomes and Measures: Primary outcomes included obstetric complications and postpartum depression compared between female residents and partners of male residents. Secondary outcomes included perceptions about support for family planning, pregnancy, or parenthood; assisted reproductive technology use; pregnancy/parenthood-based mistreatment; neonatal complications; and well-being, compared between female and male residents. Results: A total of 5692 residents from 325 US general surgery programs participated (81.2% response rate). Among them, 957 residents (16.8%) reported a pregnancy during clinical training (692/3097 [22.3%] male vs 265/2595 [10.2%] female; P < .001). Compared with male residents, female residents more frequently delayed having children because of training (1201/2568 [46.8%] females vs 1006/3072 [32.7%] males; P < .001) and experienced pregnancy/parenthood-based mistreatment (132 [58.1%] females vs 179 [30.5%] males; P < .001). Compared with partners of male residents, female residents were more likely to experience obstetric complications (odds ratio [OR], 1.42; 95% CI, 1.04-1.96) and postpartum depression (OR, 1.63; 95% CI, 1.11-2.40). Pregnancy/parenthood-based mistreatment was associated with increased burnout (OR, 2.03; 95% CI, 1.48-2.78) and thoughts of attrition (OR, 2.50; 95% CI, 1.61-3.88). Postpartum depression, whether in female residents or partners of male residents, was associated with resident burnout (OR, 1.93; 95% CI, 1.27-2.92), thoughts of attrition (OR, 2.32; 95% CI, 1.36-3.96), and suicidality (OR, 5.58; 95% CI, 2.59-11.99). Conclusions and Relevance: This study found that pregnancy/parenthood-based mistreatment, obstetric complications, and postpartum depression were associated with female gender, likely driving gendered attrition. Systematic change is needed to protect maternal-fetal health and advance gender equity in procedural fields.
RESUMO
OBJECTIVE: There is an ongoing national shortage in the vascular surgery (VS) workforce. To increase interest in the specialty, the Society for Vascular Surgery (SVS) Resident and Student Outreach Committee (RSOC) developed a dedicated general surgery (GS) resident and medical student (MS) program at the Vascular Annual Meeting (VAM) and invested in a scholarship program to help reduce attendee expenses. This study assesses the program's effectiveness, correlating recipient feedback with the likelihood of matching into a VS training program. METHODS: Records related to the SVS VAM GS resident and MS program from 2013 to 2023 were reviewed, focusing on attendee evaluations of the program. The program included a simulation session from 2013 to 2019. VS training program match rates among scholarship recipients were determined. The annual average match rate in VS was used to divide the survey responses into two groups: below average (BA) and above average (AA) match rate groups. Survey responses were based on a 5-point Likert scale and allowed for comments. Responses were divided into high value, strongly favoring the activity (scores 4-5), and low value (scores 1-3) categories. The survey responses from the group of years with AA match rates were compared with the group of years with BA rates. RESULTS: The SVS awarded 1040 GS resident and MS travel scholarships over the 10 years assessed. Overall, applicants had a 43% success rate in receiving a scholarship. During the study period, the annual number of applicants increased, whereas the number of scholarships and match success rates significantly decreased. The average match rate into VS among scholarship recipients was 50.2%. The survey response rate was 33%. During AA match rate years, evaluations for simulation allotted time and lectures were significantly more likely to be high value compared with BA years. Simulation content and the residency fair consistently had the most favorable evaluations (>90% high value), and overall, the program had a consistently positive impact on recipients' interest in VS (>90% high value). Trainees in the AA group were significantly more likely to provide positive comments (73% vs 55%; P < .001). Numerous recipients commented on the need for a dedicated space to interact with faculty and mentors and highlighted simulation as the standout aspect of the program. CONCLUSIONS: The SVS VAM RSOC program is positively correlated with attendee interest in VS, with approximately 50% of scholarship recipients matching into the field. The quality of the program and the number of scholarships correlate with VS match rates. Additional investments in similar programs could help close the workforce gap.
RESUMO
BACKGROUND: There is a push toward shorter length of stay (LOS) after surgery by hospitals, payers, and policymakers. However, the extent to which these changes have shifted the occurrence of complications to the postdischarge setting is unknown. The objectives of this study were to (1) evaluate changes in LOS and postdischarge complications over time and (2) assess factors associated with postdischarge complications. STUDY DESIGN: Patients who underwent surgery across five specialties (colorectal, esophageal, hepatopancreatobiliary [HPB], gynecology, and urology) were identified from the American College of Surgeons National Surgical Quality Improvement Program (ACS NSQIP) procedure-targeted database (2014-2019). Trends in the proportion of postdischarge complications within 30 days of surgery and predictors of postdischarge complications were assessed using multivariable logistic regression. RESULTS: Among 538,172 patients evaluated, median LOS decreased from 3 (2014) to 2 days (2019) (p < 0.001). Overall, 12.2% of patients experienced a 30-day complication, with 50.4% occurring postdischarge. with the highest in hysterectomy (80.9%), prostatectomy (74.6%), and cystectomy (54.6%). The overall postoperative complication decreased, but the proportion of postdischarge complications increased from 44.6% (2014) to 56.4% (2019) (p < 0.001), including surgical site infection (superficial/deep/organ space/wound dehiscence), other infection (pneumonia/urinary tract infection/sepsis), cardiovascular (myocardial infarction/cardiac arrest/stroke), and venous thromboembolism. Factors associated with an increased odds of postdischarge complications included Hispanic or other race, higher American Society of Anesthesiologists class, dependent functional status, increased body mass index, higher wound class, inpatient complication, longer operation, and procedure type (HPB/colorectal/hysterectomy/esophagectomy, vs. prostatectomy) (all p < 0.001). CONCLUSION: This comprehensive retrospective analysis across five representative surgical specialties highlighted that although LOS has decreased over time, the proportion of postdischarge complications has increased over time. Focusing on the development of a comprehensive, proactive, postdischarge monitoring system to better identify and manage postdischarge complications is necessary.

Arterial thoracic outlet syndrome (TOS) is a condition in which anatomic abnormalities in the thoracic outlet cause compression of the subclavian or, less commonly, axillary artery. Patients are usually younger and typically have an anatomic abnormality causing the compression. The condition usually goes undiagnosed until patients present with signs of acute or chronic hand or arm ischemia. Workup of this condition includes a thorough history and physical examination; chest x-ray to identify potential anatomic abnormalities; and arterial imaging, such as computed tomographic angiography or duplex to identify arterial abnormalities. Patients will usually require operative intervention, given their symptomatic presentation. Intervention should always include decompression of the thoracic outlet with at least a first-rib resection and any other structures causing external compression. If the artery is identified to have intimal damage, mural thrombus, or is aneurysmal, then arterial reconstruction is warranted. Stenting should be avoided due to external compression. In patients with symptoms of embolization, a combination of embolectomy, lytic catheter placement, and/or therapeutic anticoagulation should be done. Typically, patients have excellent outcomes, with resolution of symptoms and high patency of the bypass graft, although patients with distal embolization may require finger amputation.

The accurate effluent prediction plays a crucial role in providing early warning for abnormal effluent and achieving the adjustment of feedforward control parameters during wastewater treatment. This study applied a dual-staged attention mechanism based on long short-term memory network (DA-LSTM) to improve the accuracy of effluent quality prediction. The results showed that input attention (IA) and temporal attention (TA) significantly enhanced the prediction performance of LSTM. Specially, IA could adaptively adjust feature weights to enhance the robustness against input noise, with R2 increased by 13.18%. To promote its long-term memory ability, TA was used to increase the memory span from 96 h to 168 h. Compared to a single LSTM model, the DA-LSTM model showed an improvement in prediction accuracy by 5.10%, 2.11%, 14.47% for COD, TP, and TN. Additionally, DA-LSTM demonstrated excellent generalization performance in new scenarios, with the R2 values for COD, TP, and TN increasing by 22.67%, 20.06%, and 17.14% respectively, while the MAPE values decreased by 56.46%, 63.08%, and 42.79%. In conclusion, the DA-LSTM model demonstrated excellent prediction performance and generalization ability due to its advantages of feature-adaptive weighting and long-term memory focusing. This has forward-looking significance for achieving efficient early warning of abnormal operating conditions and timely management of control parameters.

OBJECTIVE: The purpose of this study was to create a risk score for the event of mortality within 3 years of complex fenestrated visceral segment endovascular aortic repair utilizing variables existing at the time of preoperative presentation. METHODS: After exclusions, 1916 patients were identified in the Vascular Quality Initiative who were included in the analysis. The first step in development of the risk score was univariable analysis for the primary outcome of mortality within 3 years of surgery. χ2 analysis was performed for categorical variables, and comparison of means with independent Student t-test was performed for ordinal variables. Variables that achieved a univariable P value less than 0.1 were then placed into Cox regression multivariable time dependent analysis for the development of mortality within 3 years. Variables that achieved a multivariable significance of less than 0.1 were utilized for the risk score, with point weighting based on the beta-coefficient. Variables with a beta coefficient of 0.25 to 0.49 were assigned 1 point, 0.5 to 0.74 2 points, 0.75 to 0.99 3 points, and 1.0 to 1.25 4 points. A cumulative score for each patient was then summed, the percentage of patients at each score experiencing mortality within 3 weeks was then calculated, and a comparison of score outcomes was conducted with binary logistic regression. Area under the curve analysis was performed. RESULTS: The primary outcome of mortality within 3 years of surgery occurred in 12.8% of patients (245/1916). The mean age for the study population was 73.35 years (standard deviation [SD], 8.26 years). The mean maximal abdominal aortic aneurysm (AAA) diameter was 60.43 mm (SD, 10.52 mm). The mean number of visceral vessels stented was 3.3 (SD, 0.76). Variables present at the time of surgery that were included in the risk score were: hemodialysis (3 points); age >87, chronic obstructive pulmonary disease, hypertension, AAA diameter >77 mm (all 2 points); and body mass index <20 kg/m2, female sex, congestive heart failure, active smoking, chronic renal insufficiency, age 80 to 87 years, and AAA diameter 67 to 77 mm (all 1 point). BMI >30 kg/m2 (mean, 34.46 kg/m2) and age <67 years were protective (-1 point). Testing the model resulted in an area under the curve of 0.706. Hosmer and Lemeshow goodness of fit test for logistic regression utilizing the 15 different risk score total groups revealed a model predictive accuracy of 87.3%. Significant escalations in 3-year mortality were noted to occur at scores of 6 and greater. Mean AAA diameter was significantly larger for patients who had higher risk scores (P < .001). CONCLUSIONS: A novel risk score for mortality within 3 years of fenestrated visceral segment aortic endograft has been developed that has excellent accuracy in predicting which patients will survive and derive the strongest benefit from intervention. This facilitates risk-benefit analysis and counseling of patients and families with realistic long-term expectations. This potentially enhances patient-centered decision-making.

Metal-free ring-opening metathesis polymerization (MF-ROMP) is an emerging polymerization strategy that provides access to ROMP materials by using organic initiators and photoredox catalysts. Unlike metal-mediated ROMP, MF-ROMP is not highly tolerant toward functionalized monomers. Herein, we report that pentafluorophenyl esters are polymerizable under MF-ROMP conditions to produce homopolymers, statistical copolymers, and block copolymers. Amine coupling agents were then used to install a range of functional groups via acyl substitution including alkynes, amino acid derivatives, fluorophores, and redox active moieties. Overall, these findings provide a framework to prepare functionalized ROMP polymers without the risk of metal contamination.
RESUMO
BACKGROUND: Work-related pain is a known risk factor for vascular surgeon burnout. It risks early attrition from our workforce and is a recognized threat to the specialty. Our study aimed to understand whether work-related pain similarly contributed to vascular surgery trainee well-being. METHODS: A confidential, voluntary survey was administered after the 2022 Vascular Surgery In-Service Examination to trainees in all Accreditation Council for Graduate Medical Education-accredited vascular surgery programs. Burnout was measured by a modified, abbreviated Maslach Burnout Inventory; pain after a full day of work was measured using a 10-point Likert scale and then dichotomized as "no to mild pain" (0-2) vs "moderate to severe pain" (3-9). Univariable analyses and multivariable regression assessed associations of pain with well-being indicators (eg, burnout, thoughts of attrition, and thoughts of career change). Pain management strategies were included as additional covariables in our study. RESULTS: We included 527 trainees who completed the survey (82.2% response rate); 38% reported moderate to severe pain after a full day of work, of whom 73.6% reported using ergonomic adjustments and 67.0% used over-the-counter medications. Significantly more women reported moderate to severe pain than men (44.3% vs 34.5%; P < .01). After adjusting for gender, training level, race/ethnicity, mistreatment, and dissatisfaction with operative autonomy, moderate-to-severe pain (odds ratio, 2.52; 95% confidence interval, 1.48-4.26) and using physiotherapy as pain management (odds ratio, 3.06; 95% confidence interval, 1.02-9.14) were risk factors for burnout. Moderate to severe pain was not a risk factor for thoughts of attrition or career change after adjustment. CONCLUSIONS: Physical pain is prevalent among vascular surgery trainees and represents a risk factor for trainee burnout. Programs should consider mitigating this occupational hazard by offering ergonomic education and adjuncts, such as posture awareness and microbreaks during surgery, early and throughout training.

INTRODUCTION: Carotid bifurcation stenosis may co-exist simultaneously with more proximal common carotid artery (CCA) atherosclerotic plaquing, primarily at the vessel origin in the aortic arch. This scenario is relatively infrequent and its' management does not have quality randomized data to support medical vs surgical treatment. It is logical to treat any high grade common carotid lesions proximal to a carotid bifurcation endarterectomy (CEA) site both to prevent perioperative emboli or thrombosis as well as future embolization. Prior long-term investigations of the combined treatment paradigm have been low volume analysis. Further, prior studies focus on perioperative outcomes with respect to stroke prevention. The only prior VQI study investigating mid-term outcomes following simultaneous CEA with proximal CCA endovascular therapy provided data on less than 10 patients beyond 1.5 years. The long-term follow-up (LFTU) component initiative within VQI has been emphasized in recent years, now allowing for much more robust LTFU analysis. METHODS: Four cohorts were created for perioperative outcome analysis and Kaplan Meier freedom from event analysis: CEA in isolation for asymptomatic disease; CEA in isolation for symptomatic patients; CEA with proximal CCA endovascular intervention for asymptomatic; and, CEA with proximal CCA intervention for symptomatic patients. Binary logistic multivariable regression was performed for perioperative neurological event and 90-day mortality risk determination and Cox multivariable regression analysis was performed for long term freedom from cumulative ischemic neurological event and long-term mortality analysis. Symptomatology and type of surgery (CEA with or without CCA intervention) were individual variables in the multivariable analysis. Neurological ischemic event in this study encompassed transient ischemic attack (TIA) and stroke combined. RESULTS: We noted a statistically significant (P < .001) escalation in rates of perioperative neurological event, myocardial infarction (MI), carotid re-exploration, 90 day mortality and combined neurological event and 90 day mortality moving from: A) asymptomatic CEA in isolation to B) symptomatic CEA in isolation to C) asymptomatic CEA combined with proximal CCA intervention to D) symptomatic CEA in combination with proximal CCA intervention. The positivity rate for the combined outcome of perioperative ischemic neurological event and 90 day mortality was 2.2% amongst asymptomatic CEA in isolation, 4.1% amongst symptomatic CEA in isolation, 4.4% amongst asymptomatic CEA in combination with proximal CCA intervention; and 8.8% in patients with symptomatic lesions undergoing combined CEA with proximal CCA intervention. On multivariable analysis patients undergoing CEA with proximal CCA endovascular intervention experienced greater risk for perioperative neurological ischemic event (aOR 2.03, 1.43-2.90, P < .001), combined perioperative neurological ischemic event and 90 day mortality (aOR 2.13, 1.62-2.80, P < .001), long term mortality (HR 1.62, 1.12-2.29, P < .001), and cumulative neurological ischemic event in long term follow up (HR 1.62, 1.12-2.29, P = .007). Amongst 4395 cumulative ischemic neurological events in all study patients, 34% were TIA. CONCLUSIONS: Carotid bifurcation endarterectomy in combination with proximal endovascular common carotid artery intervention caries an over two fold higher perioperative risk of neurologic ischemic event and 90 day mortality relative to CEA in isolation for asymptomatic and symptomatic cohorts respectively. After surgery, freedom from cerebral ischemia and mortality for patients undergoing dual intervention is closely aligned with patients undergoing CEA in isolation. Despite high adverse perioperative event rates for the combined CEA and CCA treatment, there is likely long term stroke reduction and mortality benefit to this approach in symptomatic patients based on the event free rates seen herein after initial hospital discharge. The benefit of treating asymptomatic tandem ICA and CCA lesions remains vague but the 4.4% perioperative neurologic event and death rate suggests that these patients would be better managed with medical therapy.

BACKGROUND: An enriching learning environment is integral to resident wellness and education. Integrated vascular (VS) and general surgery (GS) residents share 18 months of core GS rotations during the postgraduate years 1-3 (PGY1-3); differences in their experiences may help identify practical levers for change. METHODS: We used a convergent mixed-methods design. Cross-sectional surveys were administered after the 2020 American Board of Surgery In-Training Examination and Vascular Surgery In-Training Examination, assessing eight domains of the learning environment and resident wellness. Multivariable logistic regression models identified factors associated with thoughts of attrition between categorical PGY1-3 residents at 57 institutions with both GS and VS programs. Resident focus groups were conducted during the 2022 Vascular Annual Meeting to elicit more granular details about the experience of the learning environment. Transcripts were analyzed using inductive and deductive logics until thematic saturation was achieved. RESULTS: Surveys were completed by 205 VS and 1198 GS PGY1-3 residents (response rates 76.8% for VS and 82.5% for GS). After adjusting for resident demographics, PGY level, and program type, GS residents were more likely than their VS peers to consider leaving their programs (odds ratio [OR]: 2.61, 95% confidence interval [CI]: 1.37-4.99). This finding did not persist after adjusting for differences in perceptions of the learning environment, specifically: GS residents had higher odds of mistreatment (OR: 1.99, 95% CI: 1.36-2.90), poorer work-life integration (OR: 2.88, 95% CI: 1.41-5.87), less resident camaraderie (OR: 3.51, 95% CI: 2.26-5.45), and decreased meaning in work (OR: 2.94, 95% CI: 1.80-4.83). Qualitative data provided insight into how the shared learning environment was perceived differently: (1) vascular trainees expressed that early specialization and a smaller, more invested faculty allow for an apprenticeship model with early operative exposure, hands-on guidance, frequent feedback, and thus early skill acquisition (meaning in work); (2) a smaller program is conducive to closer relationships with co-residents and faculty, increasing familiarity (camaraderie and work-life integration); and (3) due to increased familiarity with program leadership, vascular trainees feel more comfortable reporting mistreatment, allowing for prompt responses (mistreatment). CONCLUSIONS: Despite sharing a learning environment, VS and GS residents experience training differently, contributing to differential thoughts of attrition. These differences may be attributable to intrinsic features of the integrated training paradigm that are not easily replicated by GS programs, such as smaller program size and higher faculty investment due to early specialization. Alternative strategies to compensate for these inherent differences should be considered (eg, structured operative entrustment programs and faculty incentivization).
RESUMO
BACKGROUND: The purpose of this study is to compare both perioperative as well as long-term outcomes of patients undergoing carotid endarterectomy (CEA) for asymptomatic carotid bifurcation stenosis based on duplex ultrasound in isolation relative to a combination of duplex and more advanced imaging. METHODS: All CEA in the VQI between January 2003 and May 2022 were queried. We identified 171,816 CEAs in the database. Exclusions were symptomatic carotid lesion (57,742), lack of imaging documentation (908), lack of advanced imaging status (1,816), simultaneous additional arterial intervention in the carotid, coronary, or peripheral arterial system (n = 4,118), and anatomic high-risk status for CEA (n = 4,071). Included patients were then placed into 1 of 2 cohorts: patients undergoing CEA based on duplex imaging alone (n = 33,437) and those undergoing CEA based on advanced imaging (CTA, MRA, or invasive angiography) with or without duplex (n = 69,715). We performed multivariable analysis for the following outcomes utilizing CEA based on duplex in isolation as 1 of the variables: perioperative neurological ischemic event utilizing binary logistic regression; combined 90-day mortality and neurological ischemic event utilizing binary logistic regression; neurological event in long-term follow-up with date of surgery serving as time zero; time dependent Cox regression analysis; mortality in long-term follow-up utilizing time-dependent Cox regression. RESULTS: Carotid endarterectomy based on duplex alone and CEA based on advanced imaging had essentially equivalent rates of 90-day mortality (0.9% vs. 1.0%, P = 0.108); combined perioperative neurological event and 90-day mortality (2.0% vs. 2.2%, P = 0.042); and, return to the operating room (1.6% vs. 1.7%, P = 0.154). On multivariable analysis CEA based on advanced imaging was noted to have a slightly higher absolute rate of perioperative neurological event without achieving multivariable significance (1.3% vs. 1.2%, adjusted odds ratio 1.11 (0.98-1.25), P = 0.092. CEA based on advanced imaging had a higher rate of neurological event after index hospital admission relative to duplex in isolation (hazard ratio (HR) 1.44 (1.31-1.60), P < 0.001). However, the absolute percentage difference was just 0.5% (1.6% vs. 2.1%). CEA based on duplex alone was associated with a slightly increased risk of mortality in LTFU (HR 1.16 (1.11-1.21), P < 0.001). At 5 years the absolute risk of mortality was less than 1% different between the cohorts. CONCLUSIONS: Performing CEA for asymptomatic bifurcation stenosis based on duplex ultrasound alone is a safe practice which achieves clinically equivalent perioperative and long-term freedom from cerebral ischemia and mortality relative to CEA based on advanced imaging. This has potential implications for health care cost saving as well as avoidance of radiation and iodinated contrast.

Endovascular aortic aneurysm repair and thoracic endovascular aortic repair have been shown to reduce blood loss, operative time, length of hospital stay, mortality, and morbidity compared with open surgical repair for abdominal aortic aneurysms and thoracic aortic aneurysms. However, there are anatomical constraints that limit the application of the endovascular approach in 30% to 40% of patients, including those with short necks, excessive angulation, or aneurysms with the involvement of aortic side branches such as supra-aortic trunks, arch aneurysms, visceral arteries, or internal iliac arteries.

Nutcracker syndrome is an extrinsic compression of the left renal vein by the superior mesenteric artery anteriorly and aorta posteriorly, resulting in hallmark manifestations of hematuria, proteinuria, and flank and/or pelvic pain. This report illustrates the case of a patient with a history of left flank pain and intermittent gross hematuria every 2 weeks. The patient denies any pelvic pain or gastrointestinal or lower extremity symptoms. Urinalysis revealed red blood cells, but no infection was noted. The cystoscopy findings were normal. Computed tomography urography showed left renal vein and duodenal compression between the aorta and superior mesenteric artery with a narrow aortic-superior mesenteric artery angle. The patient underwent left renal vein transposition to the distal inferior vena cava via a transabdominal approach. The left renal vein was transected at the inferior vena cava; however, the length was too short to create a tension-free anastomosis. Thus, a bovine pericardium sheet was tubularized and used as an interposition graft. The patient recovered well and is symptom-free. Left renal vein transposition is a well-described surgical technique in the treatment of nutcracker syndrome. The use of a vein or prosthetic graft has been described. This case demonstrates the use of an alternate conduit for reconstruction.
RESUMO
OBJECTIVE: Mistreatment among vascular surgery trainees is a known risk factor for physician burnout. This study aims to characterize forms of and identify sources of mistreatment. METHODS: This is a cross-sectional study of United States vascular surgery trainees who voluntarily participated in an anonymous survey administered after the 2021 Vascular Surgery In-Training Examination. The primary outcome measures were self-reported mistreatment and sources of mistreatment between genders. Logistic regression was used for multivariable analysis. RESULTS: Representing all 125 vascular surgery training programs, 510 trainees (66.9% male) participated in the survey (83.6% response rate). Mistreatment was reported by 54.8% of trainees, with twice as many women reporting as men (82.3% vs 41.0%; P < .001). Women reported higher rates of being shouted at (44.1% vs 21.1%; P < .001); repeatedly reminded of errors (24.3% vs 16.1%; P = .04); ignored/treated hostilely (28.9% vs 10.5%; P < .001); subjected to crude/sexually demeaning remarks, stories, jokes (19.2% vs 2.1%; P < .001); evaluated by different standards (29.3% vs 2.1%; P < .001); and mistaken for a non-physician (75.2% vs 3.5%; P < .001). Among trainees reporting bullying, attendings were the most common source (68.5%). Patients and their families were the most common source of sexual harassment (66.7%), gender discrimination (90.4%), and racial discrimination (74.4%). Compared with men, women identified more patients and families as the source of bullying (50.0% vs 29.7%; P = .005), gender discrimination (97.2% vs 50.0%; P < .001), and sexual harassment (78.4% vs 27.3%; P = .003). Compared with men, women more frequently felt unprepared to respond to the behavior in the moment (10.4% vs 4.6%; P = .002), did not know how to report mistreatment at their institution (7.6% vs 3.2%; P = .04), and did not believe that their institution would take their mistreatment report seriously (9.0% vs 3.9%; P = .002). On multivariable analysis, female gender was an independent risk factor for both gender discrimination (odds ratio, 56.62; 95% confidence interval, 27.89-115) and sexual harassment (odds ratio, 26.2; 95% confidence interval, 3.34-14.8) when adjusting for children, training year, relationship status, and training program location. CONCLUSIONS: A majority of vascular surgery trainees experience mistreatment during training. Sources and forms of abuse are varied. Understanding the sources of mistreatment is critical to guide intervention strategies such as faculty remediation and/or sanctions; allyship training for staff, residents, and faculty; and institutional procedures for patient-initiated abuse.

BACKGROUND: Percutaneous endovascular treatment for arterial vascular diseases has revolutionized vascular care. While these procedures offer improved morbidity, mortality, and length of stay (LOS), their effect on postdischarge complications is unknown. The objectives of the study were to evaluate trends in LOS and postdischarge complications over time and to assess factors associated with postdischarge complications. METHODS: Patients who underwent surgery for common vascular pathologies (abdominal aortic aneurysm, aortoiliac occlusive disease, lower extremity disease, and carotid stenosis) were identified from the American College of Surgeons National Surgical Quality Improvement Program procedure-targeted database (2014-2019). Outcomes included LOS, 30-day complications, and proportions of postdischarge complications. Predictors of postdischarge complications were assessed using a multivariable logistic regression. RESULTS: Of 80,311 patients evaluated, median LOS did not change from 2014 to 2019 (2, interquartile range 1-5). Overall, 15.7% of patients experienced any 30-day complication, with 31.3% occurring after discharge. The proportion of postdischarge complications increased from 29.1% (2014) to 35.9% (2019), P < 0.001. With exception of carotid procedures, endovascular procedures had lower overall complication rates than open procedures; however, there was an increased proportion of postdischarge complications for endovascular procedures (all P < 0.001). Factors associated with an increased odds of postdischarge complications included female, Black or other race, dependent functional status, underweight or obesity, increased LOS, and procedural time, all P < 0.05. CONCLUSIONS: Across 4 representative common vascular pathologies, endovascular treatments had a higher proportion of postdischarge complications compared to open procedures. Early identification and evaluation of postdischarge complications for endovascular patients may be warranted to avoid unplanned readmission.

OBJECTIVE: Racial/ethnic discrimination is one form of mistreatment and a known risk factor for physician burnout. In the present study, we aimed to characterize the forms and identify the sources of racial/ethnic discrimination among vascular surgery trainees. METHODS: We performed a cross-sectional study of U.S. vascular surgery trainees who had voluntarily participated in an anonymous survey administered after the 2021 Vascular Surgery In-Training Examination. The primary outcome measures were self-reported mistreatment and sources of mistreatment between race and ethnicity groups. We used χ2 tests and logistic regression for bivariate and multivariable analyses, respectively. RESULTS: Representing all 123 vascular surgery training programs, 510 trainees (66.9% men) participated in the survey (83.6% response rate). Most of the trainees had self-identified as White (53.1%), followed by Asian (24.4%), Hispanic/Latinx (7.6%), Black (4.2%), and other/prefer not to say (10.8%). No significant differences were found in the self-reported duty hour violations among the groups. Black (56.3%) and Asian (36.3%) trainees reported higher rates of racial/ethnic discrimination compared with the White, Hispanic/Latinx, and other/prefer not to say groups (P < .001). Patients and their families were reported as the most common source (74.7%). Other reported sources of discrimination included nurses or staff (60%), attendings (37.4%), co-residents (31.3%), and administration (16.9%). Regarding specific forms of racial discrimination, Black and Asian trainees reported the highest rates of different standards of evaluation (20% and 5.9%, respectively), being mistaken for a nonphysician (50.0% and 5.9%, respectively), slurs and/or hurtful comments (13.3% and 5.9%, respectively), social isolation (13.0% and 1.0%, respectively), and being mistaken for another trainee of the same race/ethnicity (60.0% and 33.7%, respectively). Only 62.5% of Black trainees reported their program/institution would take their mistreatment report seriously compared with the White (88.9%), Hispanic/Latinx (88.2%), Asian (83.2%), and other/prefer not to say (71.4%) trainees (P = .01). On multivariable analysis, female gender (odds ratio [OR], 2.5; 95% confidence interval [CI], 1.44-4.33), Asian race (OR, 6.9; 95% CI, 3.53-13.3), Black race (OR, 13.6; 95% CI, 4.25-43.4), and training in the Southeastern United States (OR, 3.8; 95% CI, 1.17-12.80) were risk factors for racial/ethnic discrimination. CONCLUSIONS: The results from the survey revealed that racial/ethnic discrimination persists in surgical training programs, with Asian and Black trainees reporting higher rates than other racial and ethnic groups. Overall, patients and family members were the most common source of racial/ethnic discrimination. However, faculty, staff, and co-trainees also contributed to racial/ethnic discrimination. Further interventions that optimize diversity, equity, and inclusion strategies and policies to address all forms of racial/ethnic discrimination with faculty, staff, and patients within the hospital are critically needed.

BACKGROUND: Ischemic stroke is a devastating complication of thoracic endovascular aortic repair (TEVAR). This risk may be higher in more proximal aneurysms that require arch manipulation. The purpose of this study is to (1) describe 30-day stroke and death rates in patients undergoing TEVAR, (2) compare stroke rates in patients undergoing TEVAR for arch versus descending aneurysm pathology, and (3) identify predictive factors associated with stroke after TEVAR. METHODS: The Vascular Quality Initiative registry was queried (2015-2021) for TEVAR procedures performed for degenerative aneurysms. Our primary outcomes were any stroke or death at 30 days. Patient-, procedure-, and hospital-level predictors of stroke were assessed using multivariable Poisson regression. RESULTS: Among 3,072 patients with degenerative aneurysms (197 [6.4%] arch versus 2,875 [93.6%] descending) treated with elective TEVAR, the median age was 73 years (interquartile range 67-79) and 54.8% were male. Within the arch aneurysm group, there were 27.4% zone 0, 22.8% zone 1, and 49.8% zone 2 interventions. Overall 30-day stroke and death rates were 3.2% and 3.8%. The distribution of stroke events was bilateral (52.9%), left carotid (20.7%), left vertebrobasilar (11.5%), right carotid (9.2%), and right vertebrobasilar (5.7%). Although mortality was similar between groups, the rate of ischemic stroke was higher for patients undergoing TEVAR for arch aneurysm versus descending aneurysms (7.1% arch versus 2.9% descending, P = 0.001). Factors that were associated with ischemic stroke after TEVAR included age (>79 years, relative risk [RR] 1.79, 95% confidence interval [CI] 1.08-2.98 vs. <79 years), dependent functional status (RR 1.73, 95% CI 1.07-2.78), procedural time (RR 1.25, 95% CI 1.15-1.36), and endovascular intervention for supra-aortic trunk revascularization (RR 2.66, 95% CI 1.06-6.70 versus no intervention). CONCLUSIONS: Ischemic stroke risk after TEVAR was increased for arch aneurysms compared to descending aneurysms. More proximal zone coverage and endovascular interventions on the supra-aortic trunks were associated with increasing risk for stroke. Adequate preparation for stroke prevention is necessary prior to TEVAR with supra-aortic trunk revascularization.
