Abstract
Accelerated medical school curricula, such as three-year programs, have gained attention in recent years but studies evaluating their impact are still scarce. This study examines the Fully Integrated Readiness for Service Training (FIRST) program, a three-year accelerated pathway, to assess its impact on students' academic performance preparedness for residency. In this observational study, we compared the academic outcomes of FIRST program students to traditional four-year curriculum students from 2018 to 2023. We analyzed multiple metrics, including exam performance (United States Medical Licensing Examination Step scores, shelf exam scores, and pre-clinical course scores) and clinical performance scores during the application and individualization phases. Analysis of Variance was used to examine the effect of accelerated pathway program experience relative to traditional 4-year medical school curriculum on the learning outcomes. FIRST program students were on average 1.5 years younger upon graduation than their traditional peers. While FIRST program students scored slightly lower on Step 2 Clinical Knowledge (CK), they exhibited no significant differences in other exam scores or clinical performance relative to the traditional students. Notably, FIRST students achieved equivalent clinical performance ratings during critical clerkships and rotations. Our findings suggest that a three-year medical school curriculum can effectively prepare students for residency and produce graduates with comparable medical knowledge and clinical skills, offering potential benefits in terms of financial relief and personal well-being for medical students.

Abstract
OBJECTIVE The aim of this study was to evaluate the 5-year outcomes of fenestrated/branched endovascular aortic repair (F/BEVAR) for the treatment of complex aortic aneurysms stratified by the aneurysm extent. METHODS Patients with the diagnosis of complex aortic aneurysm, who underwent F/BEVAR at a single center were included in this study and retrospectively analyzed. The cohort was divided according to the aneurysm extent, comparing group 1 (types I-III thoracoabdominal aneurysms [TAAAs]), group 2 (type IV TAAAs), and group 3 (juxtarenal [JRAAs], pararenal [PRAAs], or paravisceral [PVAAs] aortic aneurysms). The primary endpoints were 30-day and 5-year survival. The secondary endpoints were technical success, occurrence of spinal cord ischemia, primary patency of the visceral arteries, freedom from target vessel instability, and secondary interventions. RESULTS Of 436 patients who underwent F/BEVAR between July 2012 and May 2023, 131 presented with types I to III TAAAs, 69 with type IV TAAAs, and 236 with JRAAs, PRAAs, or PVAAs. All cases were treated under a physician-sponsored investigational device exemption protocol with a patient-specific company-manufactured or off-the-shelf device. Group 1 had significantly younger patients than group 2 or 3 respectively (69.6 ± 8.7 vs 72.4 ± 7.1 vs 73.2 ± 7.3 years; P < .001) and had a higher percentage of females (50.4% vs 21.7% vs 17.8%; P < .001). Prior history of aortic dissection was significantly more common among patients in group 1 (26% vs 1.4% vs 0.9%; P < .001), and mean aneurysm diameter was larger in group 1 (64.5 vs 60.7 vs 63.2 mm; P = .033). Comorbidities were similar between groups, except for coronary artery disease (P < .001) and tobacco use (P = .003), which were less prevalent in group 1. Technical success was similar in the three groups (98.5% vs 98.6% vs 98.7%; P > .99). The 30-day mortality was 4.5%, 1.4%, and 0.4%, in groups 1, 2, and 3, respectively, and was significantly higher in group 1 when compared with group 3 (P = .01). The incidence of spinal cord ischemia was significantly higher in group 1 compared with group 3 (5.3% vs 4.3% vs 0.4%; P = .004). The 5-year survival was significantly higher in group 3 when compared with group 1 (P = .01). Freedom from secondary intervention was significantly higher in group 3 when compared with group 1 (P = .003). At 5 years, there was no significant difference in freedom from target vessel instability between groups or primary patency in the 1652 target vessels examined. CONCLUSIONS Larger aneurysm extent was associated with lower 5-year survival, higher 30-day mortality, incidence of secondary interventions, and spinal cord ischemia. The prevalence of secondary interventions in all groups makes meticulous follow-up paramount in patients with complex aortic aneurysm treated with F/BEVAR.

Abstract
OBJECTIVE The modern treatments of trauma have changed in recent years. We aim to evaluate the factors associated with limb salvage and mortality after extremity arterial trauma, especially with respect to the type of conduit used in revascularization. METHODS The National Trauma Data Bank was queried to identify patients with upper and lower extremity (UE and LE) arterial injuries between 2016 and 2020. The patients were stratified by the types of arterial repair. The primary outcome was in-hospital mortality. RESULTS 8780 patients were found with 5054 (58%) UE and 3726 (42%) LE injuries. Eighty-three percent were men, and the mean age was 34 ± 15 years. Penetrating mechanism was the predominant mode of injury in both UEs and LEs (73% and 67%, respectively) with a mean injury severity score of 14 ± 8. For UEs, the majority underwent primary repair (67%, P < .001), whereas the remainder received either a bypass (20%) or interposition graft (12%). However, LEs were more likely to receive a bypass (52%, P < .00001) than primary repair or interposition graft (34% and 14%, respectively). Compared with the extremely low rates of amputation and mortality among UE patients (2% for both), LE injuries were more likely to result in both amputation (10%, P < .001) and death (6%, P < .001). Notably, compared with primary repair, the use of a prosthetic conduit was associated with a 6.7-fold increase in the risk of amputation in UE and a 2.4-fold increase in LE (P < .0001 for both). Synthetic bypasses were associated with a nearly 3-fold increase in return to the operating room (OR) in UE bypasses (P < .05) and a 2.4-fold increase in return to the OR in LE bypasses (P < .0001). CONCLUSIONS In recent years, most extremity vascular trauma was due to penetrating injury with a substantial burden of morbidity and mortality. However, both limb salvage rates and survival rates have remained high. Overall, LE injuries more often led to amputation and mortality than UE injuries. The most frequently used bypass conduit was vein, which was associated with less risk of unplanned return to the OR and limb loss, corroborating current practice guidelines for extremity arterial trauma.

Abstract
BACKGROUND The experiences of pager use among trainees across medical specialties is underexplored. The aim of this study was to assess experiences of pager burden and communication preferences among trainees in different specialties. METHODS An online survey was developed to assess perceived pager burden (eg, pager volume, mistake pages, sleep, and off-time interruptions) and communication preferences at a tertiary center in the United States. All residents and fellows were eligible to participate. Responses were grouped by specialty: General surgery [GS], Surgical subspecialty [SS], Medicine, Anesthesiology, and Psychiatry. Multivariable linear regression was used to assess factors associated with pager burden. Free text responses were analyzed using open coding methods. RESULTS Of the total 306 responses, the majority were female (58.8%), 30-39 years (59.2%), and White (70.6%). Specialty breakdown was: Medicine (40.2%), Psychiatry (10.8%), SS (18.0%), GS (5.6%), and Anesthesiology (3.6%). GS respondents reported receiving more mistake pages (P < .001), spending more time redirecting mistake pages (P = .003), and having the highest sleep time disruptions (P < .001). For urgent communications, surgical trainees preferred physical pagers, while nonsurgical trainees preferred smartphone pagers (P = .001). "Receive fewer nonurgent pages" was the most common change respondents desired. DISCUSSION In this single center study, subjective experiences of pager burden were disproportionately high among GS trainees. Reducing nonurgent and mistake pages are potential targets for improving trainee communication experiences. Hospitals should consider incorporating trainee preferences into paging systems. Additional studies are warranted to increase the sample size, assess generalizability of the findings, and contextualize trainee experiences with objective hospital-level paging data.

Abstract
Pectoralis minor syndrome (PMS) and quadrilateral space syndrome (QSS) are uncommon neurovascular compression disorders affecting the upper extremity. PMS involves compression under the pectoralis minor muscle, and QSS results from compression in the quadrilateral space-both are classically observed in overhead-motion athletes. Diagnosing PMS and QSS may be challenging due to variable presentations and similarities with other, more common, upper-limb pathologies. Although there is no gold standard diagnostic, local analgesic muscle-block response in a patient with the appropriate clinical context is often all that is required for an accurate diagnosis after excluding more common etiologies. Treatment ranges from conservative physical therapy to decompressive surgery, which is reserved for refractory cases or severe, acute vascular presentations. Decompression generally yields favorable outcomes, with most patients experiencing significant relief and restored baseline function. In conclusion, PMS and QSS, although rare, can cause debilitating upper-extremity symptoms; accurate diagnosis and appropriate treatment offer excellent outcomes, alleviating pain and disability.

Abstract
Richard Nixon injured his left knee in a limousine door while campaigning in North Carolina in 1960, resulting in septic arthritis that required a multi-day admission to Walter Reed Hospital. Still ill for the first presidential debate that fall, Nixon lost the contest based more on his appearance than his performance. Partly as a result of this debate, he was defeated by John F. Kennedy in the general election. Because of his leg wound, Nixon developed chronic DVTs in that limb, including a severe thrombus in 1974 that embolized to his lung, required surgery, and prevented him from testifying at the Watergate Trial. Episodes like this one highlight the value of studying the health of famous figures, where even the most minor injuries have the potential to influence world history.

Abstract
Identification of surgical mentors is associated with medical student interest in surgical careers. Small group learning has been a fundamental component of the surgical clerkship at the University of North Carolina (UNC) School of Medicine for 14 years. The curriculum was standardized on 2018 and has long been hypothesized to facilitate mentoring relationships. In this brief report, we administered a survey that assessed the relationship between students and surgical faculty serving as small group tutors. Analysis was performed by descriptive statistics and chi-square analysis. The survey yielded an 18.8% response rate. Greater than 50% of students identified their tutor as a surgical role model. Greater than 60% of students affirmed that their tutor at least somewhat influenced their interest in surgery. Larger longitudinal studies with higher response rates are needed to assess relationships over time, and if these relationships ultimately correlate with applications made to surgical residency programs.

Abstract
OBJECTIVE Peripheral artery disease is known to affect males and females in different proportions. Disparate surgical outcomes have been quantified after endovascular aortic aneurysm repair, arteriovenous fistula creation, and treatment of critical limb ischemia. The aim of this study is to objectively quantify the sex differences in outcomes in patients undergoing open surgical intervention for aortoiliac occlusive disease. METHODS Patients were identified in the aortoiliac occlusive disease Vascular Quality Initiative database who underwent aorto-bifemoral bypass or aortic thromboendarterectomy as determined by Current Procedural Terminology codes between 2012 and 2019. Patients with a minimum of 1-year follow-up were included. Risk differences (RDs) by sex were calculated using a binomial regression model in 30-day and 1-year incidence of mortality and limb salvage. Additionally, incidence of surgical complications including prolonged length of stay (>10 days), reoperation, and change in renal function (>0.5 mg/dl rise from baseline), were recorded. Inverse probability weighting was used to standardize demographic and medical history characteristics. Multivariate logistic regression models were employed to conduct analyses of the before mentioned clinical outcomes, controlling for known confounders. RESULTS Of 16,218 eligible patients from the VQI data during the study period, 6538 (40.3%) were female. The mean age, body mass index, and race were not statistically different between sexes. Although there was no statistically significant difference detected in mortality between males and females at 30 days postoperatively, females had an increased crude 1-year mortality with an RD of 0.014 (95% confidence interval, 0.01-0.02; P value < .001. Males had a higher rate of a postoperative change in renal function with an RD of -0.02 (95% confidence interval, -0.03 to -0.01; P < .001). CONCLUSIONS Although there was no sex-based mortality difference at 30 days, there was a statistically significant increase in mortality in females after open aortoiliac intervention at 1 year based on our weighted model. Male patients are statistically significantly more likely to have a decline in renal function after their procedures when compared with females. Postoperative complications including prolonged hospital stay, reoperation, and wound disruption were similar among the sexes, as was limb preservation rates at 1 year. Further studies should focus on elucidating the underlying factors contributing to sex-based differences in clinical outcomes following aortoiliac interventions.

Abstract
BACKGROUND Numerous endovascular options have been used for the repair of juxtarenal aortic aneurysms (JRAAs) over the last 15 years. This study aims to compare the performance between the Zenith p-branch device and custom-manufactured fenestrated-branched devices (CMD) for the treatment of asymptomatic JRAA. METHODS A single-center retrospective analysis of prospectively collected data was performed. Patients with a diagnosis of JRAA submitted to endovascular repair between July 2012 and November 2021 were included in the study, being divided into 2 groups: CMD and Zenith p-branch. The following variables were analyzed: preoperative information: demographics, comorbidities, and maximum aneurysm diameter; procedural data: contrast volume, fluoroscopy time, radiation dose, estimated blood loss, and technical success; and postoperative data: 30-day mortality, duration of intensive care unit and hospital stay, major adverse events, secondary interventions, target vessel instability, and long-term survival. RESULTS From a total of 373 physician-sponsored investigational device exemption (Cook Medical devices) cases performed at our institution, 102 patients presented the diagnosis of JRAA. Of these, 14 patients were treated with the p-branch device (13.7%) and 88 (86.3%) with a CMD. Both groups presented similar demographic composition and maximum aneurysm diameter. All devices were successfully deployed, with no type I or III endoleaks observed at procedure completion. The contrast volume (P = 0.023) and radiation dose (P = 0.001) were significantly higher in the p-branch group. No significant difference was observed between the groups for the remaining intraoperative data. No paraplegia or ischemic colitis has been observed during the first 30 days after the surgical procedures. There was no 30-day mortality in either group. One major cardiac adverse event was registered in the CMD group. Early outcomes were similar in both groups. No significant difference was found between the groups with respect to the presence of type I or III endoleaks during the follow-up. From a total of 313 target vessels stented in the CMD group (mean of 3.55 per patient) and 56 in the p-branch group (mean of 4 per patient), 4.79% and 5.35% presented instability, respectively, with no difference observed between the groups (P = 0.743). Secondary interventions were required in 36.4% of the CMD cases and 50% of the p-branch group, but this was not statistically different (P = 0.382). In the p-branch cohort, 2 of 7 reinterventions (28.5%) were target vessel-related and in the CMD group, 10 of 32 secondary interventions (31.2%) were target vessel-related. CONCLUSIONS Comparable perioperative outcomes were obtained when appropriately selected patients were treated with either the off-the-shelf p-branch or CMD for JRAA. The long-term target vessel instability does not appear impacted by the presence of pivot fenestrations in comparison to other target vessel configurations. Given these outcomes, delay in CMD production time should be considered when treating patients with large juxtarenal aneurysms.

Abstract
INTRODUCTION Feedback is an essential component in complex work environments. Different generations have been shown to have different sets of values, derived from societal and cultural changes. We hypothesize that generational differences may be associated with preferred feedback patterns among medical trainees and faculty in a large academic institution. METHODS A survey was distributed to all students, residents/fellows, and faculty at a large academic medical institution from April 2020 through June 2020. Survey questions evaluated feedback methods for six domains: preparedness, performance, attitude, technical procedures, inpatient, and outpatient care. Participants selected a preferred feedback method for each category. Patient demographics and survey responses were described using frequency statistics. We compared differences in feedback preferences based on generation and field of practice. RESULTS A total of 871 participants completed the survey. Preferred feedback patterns in the medical field do not seem to align with sociologic theories of generational gaps. Most participants preferred to receive direct feedback after an activity away from their team, irrespective of their age or medical specialty. Individuals preferred direct feedback during an activity in front of their team only for technical procedures. Compared to nonsurgeons, surgeons were more likely to prefer direct feedback in front of team members for preparedness, performance, and attitude. CONCLUSIONS Generational membership is not significantly associated with preferred feedback patterns in this complex medical academic environment. Variations in feedback preferences are associated with field of practice that may be due to specialty-specific differences in culture and personality traits present within certain medical specialties, particularly surgery.

Abstract
BACKGROUND Thoracic aortic injury (TAI) is rare in the pediatric population. Thoracic endovascular aortic repair (TEVAR) is the recommended standard of care for treatment in the adult population given its association with lower rates of mortality and morbidity than traditional open repairs for treatment of TAI. However, there are unique anatomic challenges in treating pediatric patients with TEVAR which may impact the outcomes and pediatric guidelines. We aimed to compare current management trends and outcomes between different pediatric age groups using data from the National Trauma Data Bank (NTDB). METHODS We analyzed the NTDB from 2007 to 2019 using International Classification of Diseases (ICD)-9 and -10 codes to identify patients with a TAI. We excluded patients older than 21 years and any patients who died in the emergency department. The pediatric patients were stratified by age group: children (1-11 years), adolescent (12-17 years), and mature (18-21 years) patients. Patient characteristics compared included injury mechanism and severity, TAI intervention, and outcomes between the 3 groups using bivariate analysis (analysis of variance for parametric and Kruskal-Wallis for nonparametric variables). These characteristics and outcomes were also compared by TAI intervention and injury mechanism. ICD-9 and -10 procedural codes were used to identify patients who underwent TEVAR, open aortic repair (OAR), or both. The modified Poisson regression was performed with relative risk (RR) to evaluate our primary outcome measure-mortality during the trauma admission. RESULTS A total of 2,431 pediatric TAI were identified in the NTDB that met the inclusion criteria. This included 134 children (5.5%), 733 adolescent (30.2%), and 1,564 mature (64.3%) patients. Children had significantly lower median Injury Severity Scores (34.1) than the adolescent (38) or mature population (36.1) (P = 0.001). The mechanism of injury differed between age groups. Children had higher rates of blunt trauma (90.3% children, 89.6% adolescent, and 86.8% mature patients) and mature patients had higher rates of penetrating trauma (6% children, 10.1% adolescent, and 12.5% mature patients) (P < 0.001). TAI management also differed significantly between pediatric age groups. Mature patients had significantly higher rates of TEVAR (3% children, 25.2% adolescent, and 29.2% mature patients) and children were most likely to be treated with nonoperative management (NOM) (94% children, 67.9% adolescent, and 64.8% mature patients) (P < 0.001). Patients who were treated with TEVAR were discharge home most frequently (31.8% NOM, 54.1% TEVAR, 44.3% OAR, 22.2% both TEVAR and OAR). Upon modified Poisson regression analysis, patient age was not associated with an increased risk of in-hospital mortality. Intervention with TEVAR (RR: 0.22, 95% CI: 0.15-0.33, P < 0.001) and OAR (RR: 0.58, 95% CI: 0.36-0.93, P = 0.024) were associated with a lower risk of mortality than NOM. CONCLUSIONS TAI is less prevalent in children compared to adults. TEVAR for TAI is associated with lower risk of in-hospital mortality compared to both NOM and OAR without differences between pediatric subgroups. Further studies should be completed to determine the most appropriate management guidelines.

Abstract
BACKGROUND Gender disparities have been previously reported in aortic aneurysm and critical limb ischemia outcomes; however, limited info is known about disparities in aortoiliac occlusive disease. We sought to characterize potential disparities in this specific population. MATERIAL AND METHODS Patients who underwent aortobifemoral bypass and aortic thromboendarterectomy (Current Procedural Terminology codes 35646 and 35331) between 2012 and 2019 were identified in the National Surgical Quality Improvement Program database. A binomial regression model was used to estimate gender differences in 30-day morbidity and mortality. Inverse probability weighting was used to standardize demographic and surgical characteristics. RESULTS We identified 1,869 patients, of which 39.8% were female and the median age was 61 years. Age, body composition, and other baseline characteristics were overall similar between genders; however, racial data were missing for 26.1% of patients. Females had a higher prevalence of preexisting chronic obstructive pulmonary disease (20.9% vs. 14.7%, prevalence difference 6.1%, P < 0.01), diabetes mellitus (25.4% vs. 19.4%, prevalence difference 6.0%, P < 0.01), and high-risk anatomical features (39.4% vs. 33.7%, prevalence difference 5.8%, P = 0.01). Preprocedural medications included a statin in only 68.2% of patients and antiplatelet agent in 76.7% of patients. Females also had a higher incidence of bleeding events when compared to males (25.2% vs. 17.5%, standardized risk difference 7.2%, P < 0.01), but were less likely to have a prolonged hospitalization greater than 10 days (18.2% vs. 20.9%, standardized risk difference -5.0%, P = 0.01). The 30-day mortality rate was not significantly different between genders (4.7% vs. 3.6%, standardized risk difference 1.2%, P = 0.25). CONCLUSIONS Female patients treated with aortobifemoral bypass or aortic thromboendarterectomy are more likely to have preexisting chronic obstructive pulmonary disease, diabetes mellitus, and high-risk anatomical features. Regardless of a patient's gender, there is poor adherence to preoperative medical optimization with both statins and antiplatelet agents. Female patients are more likely to have postoperative bleeding complications while males are more likely to have a prolonged hospital stay greater than 10 days. Future work could attempt to further delineate disparities using databases with longer follow-up data and seek to create protocols for reducing these observed disparities.

Abstract
Lesbian, gay, bisexual, transgender, and queer/questioning (LGBTQ+) patients face challenging health care disparities. However, due to restrictions in reporting and collection of sexual orientation and gender identity (SOGI) demographic data, comprehensive studies of surgical disparities in the LGBTQ+ population are limited. This review aims to summarize the existing literature describing surgical disparities in LGBTQ+ patients and to identify areas of surgical care in which further studies are warranted. This review addresses the literature in infectious diseases, substance use disorders, bariatrics, cardiovascular medicine, oncology, and laryngology as relevant to surgical practice. Understanding the current landscape of knowledge in LGBTQ+ surgical disparities and the areas where gaps in research exist will help the surgeon to create a framework of practice to provide more equitable care to LGBTQ+ patients.

Abstract
Many of the systemic practices in medicine that have alienated lesbian, gay, bisexual, transgender, and queer or questioning (LGBTQ) individuals persist today, undermining the optimal care for these patients and isolating LGBTQ medical providers from their colleagues. The 2020 Task Force on Diversity, Equity, and Inclusion Report recently published by the Society for Vascular Surgery marked the first publication advocating for the inclusion of sexual orientation and sexual identity in the development of initiatives promoting and protecting diversity across vascular surgery. Vascular providers should be aware that it is crucial to cultivate an environment that is inclusive for LGBTQ patients because a large proportion of these patients have reported not self-disclosing their status to medical providers, either out of concern over potential personal repercussions or failing to recognize the potential relevance of LGBTQ status to their medical care. Safe Zone training has provided a standard resource for providers and staff that can be integrated into onboarding and routine training. Clarifying the current terminology for sexual orientation and identity will ensure that vascular providers will recognize patients who could benefit from screening for additional vascular risk factors relevant to this population related to sexual health, social behavior, physical health, and medical therapies. The adoption of gender neutral language on intake forms and general correspondence with colleagues is key to reducing the unintended exclusion of those with LGBTQ identities in both inpatient and outpatient environments. In many locales across the United States, the professional and personal repercussions for openly reporting LGBTQ status persist, complicating efforts toward quantifying, recognizing, and supporting these patients, practitioners, and trainees. Contributing to an inclusive environment for patients and peers and acting as a professional ally are congruent with the ethos in vascular surgery to treat all patients and colleagues with respect and optimize the healthcare of every vascular patient.

Abstract
BACKGROUND The addition of a novel education tool helps students improve understanding of general surgery topics. However, the effect of the new tool on objective exam performance is unknown. MATERIALS A 10-item card of high-yield general surgery topics was implemented in the third-year surgery clerkship. Students reviewed these topics with general surgery residents. Scores from the National Board of Medical Examiners (NBME) surgery subject exam and Step 2 Clinical Knowledge (CK) board exam were compared among students who completed the Ask-a-Resident Topic card to a control group. RESULTS Students who participated in the curriculum demonstrated significantly better scores on the NBME Surgery exam, t (236) = -2.56, P = .006. There was not a significant effect of the curriculum on Step 2 CK scores, although students who participated in the curriculum (M = 250.7, SD = 13.4) achieved higher scores than the control group (M = 247.8, SD = 14.2). DISCUSSION The novel curriculum may improve objective student performance on standardized surgery exams.

Abstract
BACKGROUND Medical education changes dramatically from preclinical to clinical years, and the learning environment becomes key as students strive to develop clinical competence and informed career decisions. This change becomes heightened on a surgical clerkship where student mistreatment is often perceived, and the fast-paced nature of surgery can result in limited resident-student interactions and time for examination preparation. OBJECTIVE To evaluate medical student and resident perception of educational strategies during a surgical clerkship and to determine whether the addition of a novel educational tool would increase satisfaction with the surgical clerkship on examination preparation and team dynamics. SETTING University of North Carolina at Chapel Hill, Department of Surgery. STUDY DESIGN During the 2018-2019 academic year, a 10-item "Ask a Resident Topics" (ART) card of high yield general surgery topics was implemented as part of the third-year surgery clerkship curriculum. Students were asked to review a topic and then discuss it with a general surgery resident. They were expected to complete at least 6 of 10 topics by the end of the rotation for credit. At the end of the year, third-year medical students were administered a 23-item survey regarding their experience on the surgery clerkship and with the ART cards. Fourth-year medical students and those students at satellite sites who did not receive the ART cards were administered the same survey, minus specific questions about the ART card, and were used as a preintervention control. General surgery residents who participated in teaching were similarly surveyed. RESULTS Of those students that completed the ART cards, 84% felt it improved their understanding of general surgery and were more likely to report the surgery clerkship prepared them well for the NBME examination compared to those who did not (Χ2 (1, N = 87) = 4.95, p = 0.03). They were also more likely to report residents were willing to discuss surgery topics with them (Χ2 (1, N = 87) = 2.77, p = 0.10). Seventy-three percent of students thought the card did not add undue stress to their clerkship. Sixty-three percent of all students felt they were a productive member of the surgery team, and this did not vary by intervention group (Χ2 (1, N = 87) = 0.03, p = 0.9). Students who completed the ART card were more likely to report being interested in surgery than those who did not (Χ2 (1, N = 87) = 4.20, p = 0.04). Hundred percent of residents surveyed felt the ART card provided value for themselves as a teacher and for the student as a learner. CONCLUSIONS The ART card is mutually beneficial to both residents and medical students during the surgical clerkship. This tool is easy to implement, helps students improve their understanding of general surgery, increases camaraderie among the surgical team, and has a positive impact on students pursuing a career in surgery.

Abstract
Diversity, equity, and inclusion represent interconnected goals meant to ensure that all individuals, regardless of their innate identity characteristics, feel welcomed and valued among their peers. Equity is achieved when all individuals have equal access to leadership and career advancement opportunities as well as fair compensation for their work. It is well-known that the unique backgrounds and perspectives contributed by a diverse workforce strengthen and improve medical organizations overall. The Society for Vascular Surgery (SVS) is committed to supporting the highest quality leadership, patient care, surgical education, and societal recommendations through promoting diversity, equity, and inclusion within the SVS. The overarching goal of this document is to provide specific context and guidance for enhancing diversity, equity, and inclusion within the SVS as well as setting the tone for conduct and processes beyond the SVS, within other national and regional vascular surgery organizations and practice settings.

Abstract
In September of 1974, Richard Nixon resigned the Presidency of the United States during an impeachment investigation concerning the Watergate Affair. One month after his resignation, the former President had an exacerbation of his chronic deep vein thrombosis. He also received a Presidential pardon from Gerald Ford on the same day that his recurrent deep vein thrombosis was diagnosed. The political, legal, and medical events that unfolded in the fall of 1974 are the substance of this report. Presidents often receive medical care that stretches the ordinary as a result of their position and the importance of their actions. The events surrounding Richard Nixon's care for deep vein thrombosis and its complications were not unusual for Presidential health care but were closely intertwined with the legal proceedings during the prosecution of the Watergate defendants.

Abstract
Background: Thoracic outlet syndrome (TOS) results from compression of neurovascular structures supplying the upper extremity as they exit the thoracic outlet. Depending on the clinical presentation, surgical decompression may be required. Objectives: Transaxillary (TA) and supraclavicular (SC) approaches are both widely utilized and deemed effective. Our objective was to review the outcomes for both approaches at our institution. Methods: A retrospective review was conducted on patients who underwent thoracic outlet decompression between 2010 and 2015. Data on demographics, comorbidities, presenting symptoms, and type of TOS (neurogenic, venous, or arterial) were collected. Operative times, length of hospital stay, perioperative complications, and outcomes were also studied. Results: A total of 82 thoracic outlet decompression procedures were performed during the study period: 42% neurogenic TOS, 46% venous TOS, and 12% arterial TOS. In total, 49% underwent TA approach and 51% underwent SC approach. Adjunct procedures were performed in 13% of patients. There were no significant differences in average operative time (151.3 ± 54.1 minutes versus 126.1 ± 36.1 minutes, P = .11) or hospital stay (2.3 ± 1.9 days versus 2.4 ± 1.4 days, P = .23) between both groups, respectively. Minor complications were seen in 6% of patients with no significant difference in both groups, whereas 6% had major complications. No perioperative or 30-day mortalities were observed. In total, 49% of patients had complete resolution of symptoms, 46% had partial improvement, and 5% had no improvement. There was no difference in symptom resolution between either group. Conclusions: TA and SC approaches are equally safe and effective for the treatment of TOS. SC decompression allows for adjunct procedures and vascular reconstructions.

Abstract
OBJECTIVE Understanding modifiable risk factors to improve surgical outcomes is increasingly important in value-based health care. There is an established association between peripheral artery disease (PAD), diabetes, and limb loss, but less is known about expected outcomes after revascularization relative to the degree of glycemic control. The purpose of this study was to determine the association between hemoglobin A1c (HbA1c) management in diabetics and surgical outcomes after open infrainguinal bypass. METHODS The Vascular Quality Initiative infrainguinal bypass module was used to identify adult patients (≥18 years) with a history of diabetes who underwent bypass for PAD between 2011 and 2018. Exclusion criteria included missing or illogical HbA1c values and if the indication for the limb treated was not PAD. Patients were categorized by preoperative HbA1c levels as low severity/controlled (<7.0%), high severity (7.0%-10.0%), and very high severity (>10.0%). Primary outcomes were 30-day incidence of major adverse cardiac events (MACEs), major adverse limb events (MALEs), ipsilateral amputation, and 1-year all-cause mortality. Thirty-day outcomes were calculated using multivariable regression to compute odds ratios; hazard ratios were calculated for all-cause mortality. All analyses were adjusted for demographics, comorbidities, and clinical characteristics. RESULTS The final sample included 30,813 operations (27,988 unique patients): 17,517 (57%) nondiabetic patients, 5194 patients with low-severity/controlled diabetes, and 8102 (26%) patients with poorly controlled diabetes, including 5531 (70%) treated with insulin. There were 6439 (21%) patients with high-severity HbA1c values and 1663 (5%) patients with very-high-severity HbA1c values. Those with a very high HbA1c level were more likely to be nonwhite, insulin dependent, and active smokers. Compared with nondiabetics, patients with very-high-severity HbA1c had an 81% increase in MACEs and 31% increase in MALEs, whereas patients with high-severity HbA1c only had a 49% increase in MACEs and a 12% increase in MALEs. Each one-step increase in severity category (eg, low to high to very high) was associated with an average 29% increase in the odds of MACEs and an 8% increase in the odds of MALEs. CONCLUSIONS Uncontrolled diabetes with an HbA1c value >10.0% was associated with significantly worse 30-day surgical outcomes. Patients with incrementally better glycemic control (HbA1c level of 7.0%-10.0%) did not suffer the same rate of complications, suggesting that preoperative attempts at improving diabetes management even slightly could lead to improved surgical outcomes in open infrainguinal bypass patients.

Abstract
A 29-year-old woman underwent esophageal stent placement after developing esophageal stenosis in the setting of tracheoesophageal fistula repair in childhood. The patient developed hemoptysis from an esophageal to aberrant right subclavian artery fistula; this was managed with several staged procedures involving arterial stent placement, carotid-to-subclavian bypass, and aberrant subclavian artery ligation. The patient then underwent pericardial patch repair of her perforated esophagus. This case illustrates the importance of understanding congenital anatomy and frequent associations, such as tracheoesophageal fistula and aberrant right subclavian artery; furthermore, it demonstrates the importance of multidisciplinary care for complex cases.

Abstract
OBJECTIVE Cigarette smoking is the leading risk factor for peripheral artery disease (PAD). Existing literature often defines smoking history in broad categories of current, former, and never smokers, which may not sufficiently identify patients at the highest risk for poor outcomes. The purpose of this study was to examine the use of more informative categorization of smoking and to determine the association with important revascularization outcomes. METHODS We conducted a retrospective review of all patients undergoing open lower extremity revascularization for symptomatic PAD, defined as claudication (Rutherford 3) or critical limb ischemia (Rutherford 4-6), during a 5-year period (2013-2017). Smoking history, demographics, and comorbidities were abstracted from electronic health records from seven hospitals within our health care system. Smoking history was defined by intensity (packs/day), duration (years), pack-year history, and cessation time. Outcomes included major adverse limb events (MALEs), death, limb loss, and amputation-free survival. Cox proportional hazards models were used to calculate hazard ratios and 95% confidence intervals (CIs) for each parameter adjusted for patients' demographics and comorbidities. Cumulative incidence is reported for outcomes at 30, 180, and 365 days of follow-up. RESULTS We identified 693 patients undergoing open lower extremity revascularization for PAD (66% critical limb ischemia; 46% diabetes). The 1-year cumulative incidence of MALEs was 29.9% (95% CI, 26.4-33.9), whereas the 1-year incidence of death was 9.8% (95% CI, 7.5-12.7). The broad classification of current and former smokers identified no statistically significant differences in any measured outcomes. Patients who smoked more than one pack/day had 1.48 (95% CI, 1.01-2.16) times increase in risk of MALEs at 1 year compared with patients who smoked one or fewer packs/day. Patients who smoked more than one pack/day also had the highest 1-year amputation incidence (12.7%). Each of the four parameters was associated with increased risk of poor outcomes, although small sample size limited the precision of our estimates. CONCLUSIONS We found that smoking intensity is particularly informative of outcomes of patients undergoing open lower extremity revascularization for symptomatic PAD. These findings lay the groundwork for future research on relevant smoking history parameters and benefits of smoking reduction and cessation for clinicians to discuss with patients and to better understand and inform patients of intervention risks and expected outcomes.

Abstract
BACKGROUND Patients undergoing vascular operations face high rates of intraoperative and postoperative complications and delayed return to baseline. Enhanced recovery after surgery (ERAS), with its aim of delivering high-quality perioperative care and accelerating recovery, appears well suited to address the needs of this population. METHODS In accordance with Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines, we performed a systematic review to characterize the use and effectiveness of ERAS in all types of vascular and endovascular operations. We queried MEDLINE (through PubMed), Embase, Web of Science, Scopus, ProQuest Dissertations and Theses Global, Cochrane Central Register of Controlled Trials, Prospero, and Google Scholar. Two reviewers independently completed screening, review, and quality assessment. Eligible articles described the use of ERAS pathways for vascular operations from January 1, 1997, through December 7, 2017. Details regarding patients' demographics and use of the ERAS pathway or selected ERAS components were extracted. When available, results including perioperative morbidity, mortality, and in-hospital length of stay were collected. The studies with control groups that evaluated ERAS-like pathways were meta-analyzed using random-effects meta-analysis. RESULTS In the final analysis, 19 studies were included: four randomized controlled trials and 15 observational studies. By Let Evidence Guide Every New Decision (LEGEND) criteria, the two good-quality studies are randomized controlled trials that evaluated a specific part of an ERAS pathway. All other studies were considered poor quality. Meta-analysis of the five studies describing ERAS-like pathways demonstrated a reduction in length of stay by 3.5 days (P = .0012). CONCLUSIONS Based on systematic review, the use of ERAS pathways in vascular surgery is limited, and existing evidence of their feasibility and effectiveness is low quality. There is minimal poor- to moderate-quality evidence describing the use of ERAS pathways in open aortic operations. There is scarce, poor-quality evidence related to ERAS pathways in lower extremity operations and no published evidence related to ERAS pathways in endovascular operations. Although the risk of bias is high in most of the studies done to date, all of them observed improvements in length of stay, postoperative diet, and ambulation. It is reasonable to consider the implementation of ERAS pathways in the care of vascular surgery patients, specifically those undergoing open aortic operations, but many of the details will be based on limited data and extrapolation from other surgical specialties until further research is done.

Abstract
OBJECTIVE To report the outcomes of patients enrolled in a physician-sponsored investigational device exemption trial for endovascular treatment of complex thoracoabdominal aortic aneurysms with fenestrated and/or branched devices. METHODS This study represents a retrospective analysis of a prospectively maintained database of patients enrolled in a physician-sponsored investigational device exemption trial for endovascular treatment of complex thoracoabdominal aneurysms between July 2012 and July 2017. Subjects included high-risk patients for open repair and patients with unsuitable anatomy for either standard endovascular aneurysm repair or Zenith (Cook Medical, Bloomington, Ind) fenestrated device. Aneurysm classification was based upon Crawford classification. We included the pararenal and paravisceral aneurysms in the type IV aneurysm group, because the repair of these aneurysms usually involved treatment of all four visceral branches. The endografts implanted were custom manufactured devices or off-the-shelf devices based on the Cook Zenith platform. Variables analyzed included preoperative demographics and comorbidities, anatomic aneurysmal characteristics, procedural details, and perioperative complications. RESULTS One -hundred fifty patients with a mean age of 71 ± 7.9 years were treated; 69% were male. Tobacco use (93%) and hypertension (91%) were the most common risk factors. Fifty-seven patients (38%) had a history of previous aortic repair. The mean aneurysm diameter was 62 ± 12 mm and 14 (9%) aneurysms were associated with chronic dissection. A total of 573 visceral vessels were incorporated (celiac artery/superior mesenteric artery [287 vessels], renal arteries [275 vessels], and 11 additional vessels) and 539 were stented. The celiac artery/superior mesenteric artery received a fenestrated design in 76.1% of cases. Branch designs were used in the renal artery in 13.2%, with the remainder treated with fenestrations. Spinal cord drainage was used in 51% of patients (76/150). The mean operative time, fluoroscopy time, and estimated blood loss were 283 ± 89 minutes, 83 ± 38 minutes, and 417 ± 404 mL, respectively. There were five patients (3.3%) with intraoperative complications, resulting in one intraoperative death. The early mortality was 2.7% (4/150). Major complications included respiratory failure in 7% (10/150), stroke and myocardial infarction in 0.7% each (1/150), and paraplegia in 2.7% (4/150). Acute kidney injury occurred in 4.7% of patients (7/150), two of whom required temporary dialysis. Thirty-nine percent of patients experienced at least one complication. Early branch vessel patency was 99.8% (525/526). Survival, primary, and primary-assisted branch patency at 2 years of follow-up were 79%, 97%, and 99%, respectively. CONCLUSIONS Endovascular repair of complex aneurysms is safe and effective when performed in a high-volume center experienced in aortic disease management. Branch vessels patency and the low incidence of paraplegia and mortality support expanded use to treat most complex thoracoabdominal aortic aneurysms.

Abstract
Fibromuscular dysplasia (FMD) is a nonatherosclerotic disease that generally affects medium-sized arteries. The distribution typically involves the renal, extracranial carotid/vertebral, and iliac arteries. FMD in other vascular beds is rare. We herein present the case of a 47-year-old female with rapid-onset bilateral digital ischemia. Initial differential diagnosis included vasospastic disorders and vasculitis. An upper extremity arteriogram was suggestive of ulnar and radial FMD. Percutaneous intervention was not successful, and the patient was managed conservatively with symptomatic improvement. This case highlights the important diagnostic and therapeutic considerations in patients with less common etiologies of upper extremity ischemia.

Abstract
Recent histologic and immunocytochemical evidence of venous leg ulcers supports the hypothesis that lesions observed at different stages of chronic venous insufficiency may be associated with, and possibly caused by, an inflammatory process. Evidence has been obtained that venous valve deficiency may be associated with leukocyte infiltration into valve leaflets; therefore, it is hypothesized that an essential event in the inflammatory cascade is the enzymatic degradation of the valve leaflets and venous wall. The metalloproteinases (MMP) in veins exposed to elevated pressures up to 6 weeks were examined in a rat femoral fistula model with venous hypertension. Zymography shows increased activity of pro-MMP-2 at 3 and 6 weeks. MMP-2 and MMP-9 activity was predominantly observed at days 7 and 21 after creation of the fistula. The degree of extracellular matrix remodeling correlates with the morphological finding of macroscopic lesions. Therefore, the MMP-2 and MMP-9 activation is already present in veins days after exposure to elevated blood pressure and coincides with periods of early alterations in the valve morphology and early forms of reflux.

Abstract
Traumatic aortic injuries in children and adolescents are rare. Although endovascular repair has become the preferred approach for such injuries in adults, open repair has endured as the gold standard in children owing mainly to the smaller aortic and access vessel diameter and the scarcity of long-term follow-up data. We report a successful endovascular repair of a traumatic thoracic aortic injury in an 8-year-old girl using a Zenith Alpha thoracic endograft (Cook Medical, Bloomington, IN). We also review the literature on endovascular treatment of traumatic aortic injuries in the pediatric population.

Abstract
BACKGROUND The dissection of the carotid sinus nerve in eversion carotid endarterectomy (eCEA) has been hypothesized to cause an increase in postoperative blood pressure (BP). The objective of this study is to evaluate the effect of eCEA on BP and changes in BP medications over the course of year-long follow-up after eCEA compared with longitudinal incision carotid endarterectomy patch angioplasty (pCEA). METHODS A retrospective review of patients who underwent CEA between July 1, 2009 and June 30, 2014 in the Vascular Surgery Department at The University of Iowa Hospital and Clinics was conducted. Demographics, comorbidities, BP, and number, dosage, and type of antihypertensive medications were collected preoperatively, at 30 days, and at 12 months. The differences in BP and medications between pCEA and eCEA patients were compared. Demographic data and comorbidities were compared using t-tests and chi-squared analysis. Differences in BP and medication dosages were analyzed using multivariate analysis of variance. RESULTS In total, 363 CEA procedures were performed during the study period, of which 275 procedures were included in the final analysis. Thirty percent of the patients underwent eCEA. Fifty-four percent of the patients who underwent eCEA and 60% of the patients who underwent pCEA were symptomatic. Thirty-day mortality was 1.4% and 12-month mortality was 6.4% for the entire population. No postoperative neurologic deficits, including stroke, were observed. Analysis of BP did not yield a significant difference among preoperative, 30-day, and 12-month follow-up measurements (P = 0.893). There was no significant change to the number and total daily dose of BP medications preoperatively, at 30 days, or at 12 months. CONCLUSIONS There is no statistical difference in mortality, morbidity, and patency rates at 30 days and 12 months between pCEA and eCEA. eCEA is also not associated with long-term BP changes compared with pCEA.

Abstract
Venous disease is the most common cause of chronic leg ulceration and represents an advanced clinical manifestation of venous insufficiency. Due to their frequency and chronicity, venous ulcers have a high socioeconomic impact, with treatment costs accounting for 1% of the health care budget in Western countries. The evaluation of patients with venous ulcers should include a thorough medical history for prior deep venous thrombosis, assessment for an hypercoagulable state, and a physical examination. Use of the CEAP (clinical, etiology, anatomy, pathophysiology) Classification System and the revised Venous Clinical Severity Scoring System is strongly recommended to characterize disease severity and assess response to treatment. This venous condition requires lifestyle modification, with affected individuals performing daily intervals of leg elevation to control edema; use of elastic compression garments; and moderate physical activity, such as walking wearing below-knee elastic stockings. Meticulous skin care, treatment of dermatitis, and prompt treatment of cellulitis are important aspects of medical management. The pharmacology of chronic venous insufficiency and venous ulcers include essentially two medications: pentoxifylline and phlebotropic agents. The micronized purified flavonoid fraction is an effective adjunct to compression therapy in patients with large, chronic ulceration.

Abstract
BACKGROUND Many patients with peripheral vascular disease (PAD) requiring revascularization do not have adequate ipsilateral great saphenous vein (GSV) for constructing a bypass because of intrinsic vein disease or prior harvesting for limb or coronary bypass. Prosthetic conduits have poor long-term patency, especially for distal bypass. With advancing endovascular sophistication, tibial angioplasty may be a good revascularization option, but we hypothesize that using spliced arm vein for distal lower extremity bypass is still a well-tolerated and more durable solution. METHODS A retrospective chart review was conducted of all PAD patients undergoing lower extremity bypass or tibial angioplasty for lifestyle-limiting claudication or critical limb ischemia at a single institution over a 7-year period. Statistical analysis was conducted by Kaplan-Meier survival analysis and Cox proportional hazards model. Statistical significance was set at P = 0.05. RESULTS From 2005 to 2012, there were 120 patients who underwent infrageniculate revascularization with conduit other than GSV. Over half of the patients (66 patients, 71.2% male, mean age 62 years) underwent bypass operations using arm vein conduit, and 88% of those bypasses were to tibial vessels. Patency was 100% at 1 year and 85% at 2 years. There was no impact on patency or amputation rate based on the source of vein or the number of splices. Forty-three patients underwent tibial angioplasty and patency was 70% at 1 year and 50% at 2 years. CONCLUSIONS When GSV is not available, spliced arm vein grafts provide durable lower extremity revascularization with favorable patency and limb preservation rates. Spliced arm vein grafts should be considered over prosthetic grafts and angioplasty alone in patients with distal occlusive disease.

Abstract
In September of 1974, Richard Nixon resigned the Presidency of the United States during an impeachment investigation concerning the Watergate Affair. One month after his resignation, the former President had an exacerbation of his chronic deep vein thrombosis. He also received a Presidential pardon from Gerald Ford on the same day that his recurrent deep vein thrombosis was diagnosed. The political, legal, and medical events that unfolded in the fall of 1974 are the substance of this report. Presidents often receive medical care that stretches the ordinary as a result of their position and the importance of their actions. The events surrounding Richard Nixon's care for deep vein thrombosis and its complications were not unusual for Presidential health care but were closely intertwined with the legal proceedings during the prosecution of the Watergate defendants.
