Upper-limb neurovascular compression, pectoralis minor and quadrilateral space syndromes: A narrative review of current literature.

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.

Five-year outcomes of fenestrated and branched endovascular repair of complex aortic aneurysms based on aneurysm extent.

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.

Academic performance of students in an accelerated medical pathway.

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.

Current outcomes following upper and lower extremity arterial trauma from the National Trauma Data Bank.

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.

Perceived Pager Burden Among Trainees Across Medical Specialties.

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.

Gender disparities in patients with aortoiliac disease requiring open operative intervention.

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.

Outcome Analysis Comparing Asymptomatic Juxtarenal Aortic Aneurysms Treated with Custom-Manufactured Fenestrated-Branched Devices and the "Off-The-Shelf" Zenith p-Branch Device.

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.

Preferred Feedback Styles Among Different Groups in an Academic Medical Center.

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.

Richard Nixon's Left Knee and Its Impact on American History.

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.

Trends and Outcomes in Management of Thoracic Aortic Injury in Children, Adolescent, and Mature Pediatric Patients Using Data from the National Trauma Data Bank.

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.

Small Group Tutorial Curriculum During Third Year Surgical Clerkship and Identification of Surgical Role Models.

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.

The State of the LGBTQ+ Community in Surgery.

The LGBTQ+ community is a diverse community that faces unique needs and multidimensional form of discrimination. Cultural awareness and awareness of intersectionality of experiences are essential in creating an equitable environment for health care professionals and patients.

Analysis of wound healing time and wound-free period in patients with chronic limb-threatening ischemia treated with and without revascularization.

BACKGROUND: The traditionally reported outcomes for patients with ischemic wounds have centered on amputation-free survival. However, that discounts the importance of other patient-centered outcomes such as the wound healing time (WHT) and wound-free period (WFP). We evaluated the long-term wound outcomes of patients treated for chronic limb-threatening ischemia at our institution. METHODS: From 2014 to 2017, we identified all patients with chronic limb-threatening ischemia and ischemic wounds using symptomatic and hemodynamic criteria. The primary data included the wound size, wound location, WIfI (wound, ischemia, foot infection) grade, WHT, WFP, minor and major amputation, and death. Wounds were not considered healed if the patient had required a major amputation or had died before wound healing. The WHT was calculated as the interval in days between the diagnosis and determination of a healed wound. The WFP was calculated as the interval in days between a healed wound and wound recurrence, major amputation, death, or the end of the study period. A comparison of the wound healing parameters stratified by revascularization status was performed using the Student t test. A generalized linear model adjusted for age, sex, initial wound size, and WIfI grade was used to evaluate the risk of wound healing with and without revascularization. RESULTS: A total of 256 patients had presented with 372 wounds. Of the 256 patients, 48% had undergone revascularization. During the study period, 97 minor amputations and 100 major amputations had been required, and 132 patients had died. The average wound size was 13.9 ± 52.0 cm2; however, for the 155 wounds that had healed, the average size was only 4.0 ± 9.6 cm2 (P = .002). No differences were found in the wound size when stratified by revascularization status (P = .727). Adjusted for the initial wound size, the risk of wound healing was not different when stratified by revascularization (risk ratio, 1.22; 95% confidence interval, 0.80-1.87; P = .354). For those whose wounds had healed, the average WHT and WFP were 173 ± 169 days and 775 ± 317 days, respectively. The WHT was not faster for the revascularized group (155 days vs 188 days; P = .221). When stratified by revascularization status, the rate of wound recurrence was 4.6 vs 8.9 wounds per 100 person-years for the revascularized and nonrevascularized groups, respectively (P = .125). CONCLUSIONS: In our study, we found that, except for patients who presented with severe ischemia, revascularization was not associated with improved rates of wound healing. Among the wounds that healed, regardless of the initial ischemia grade, revascularization was not associated with a faster WHT or longer WFPs.

Gender Disparities in Aortoiliac Revascularization in Patients with Aortoiliac Occlusive Disease.

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.

Surgical Implications of LGBTQ+ Health Disparities: A Review.

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.

A Novel Educational Tool to Improve Medical Student Knowledge Acquisition During Surgical Rotations.

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.

Sexual orientation, gender identity, and gender expression: From current state to solutions for the support of lesbian, gay, bisexual, transgender, and queer/questioning patients and colleagues.

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.

Enhancing Medical Student Education and Combating Mistreatment During a Surgery Clerkship With a Novel Educational Tool: A Pilot Study.

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.

Performance of Viabahn balloon-expandable stent compared with self-expandable covered stents for branched endovascular aortic repair.

OBJECTIVE: The objective of this study was to compare the performance between the Viabahn balloon-expandable stent (VBX; Viabahn [W. L. Gore & Associates, Flagstaff, Ariz]) and a covered self-expandable stent (SES; Fluency [Bard Peripheral Vascular, Tempe, Ariz]) used as bridging stents for directional branches during fenestrated or branched endovascular aneurysm repair of complex aortic aneurysms. METHODS: Patients with thoracoabdominal aortic aneurysms (type I-IV) or pararenal aortic aneurysms either at high risk for open repair or unsuitable for endovascular repair with commercially available devices were prospectively enrolled in a physician-sponsored investigational device exemption trial. Descriptive statistics of the cohort included demographics, risk factors, and anatomic and device characteristics. Individual branches were grouped as either VBX or SES and had data analyzed for primary patency, branch-related type I or type III endoleaks, branch instability, branch-related secondary intervention, and branch-related aortic rupture or death. Categorical variables were expressed as total and percentage, and continuous variables were expressed as median (interquartile range). Kaplan-Meier curves were used to estimate long-term results. Groups were compared with the log-rank test. P value <.05 was considered statistically significant. RESULTS: During the period from July 2012 through June 2019, there were 263 patients treated for complex aortic aneurysm (thoracoabdominal aortic aneurysm) with fenestrated or branched endografts. The devices used were either custom-manufactured devices or off-the-shelf p-Branch or t-Branch (Cook Medical, Bloomington, Ind) devices. The median age was 71 years (interquartile range, 66-79 years); 70% were male, and 81% were white. The most common cardiac risk factors were smoking (92%), hypertension (91%), hyperlipidemia (78%), and chronic obstructive pulmonary disease (52%). The total number of vessels incorporated into the repair was 977, with branches representing 18.4% (179 branches). Among these 179 branches, the celiac artery, superior mesenteric artery, right renal artery, and left renal artery received 54 (30%), 56 (31%), 38 (21%), and 31 (18%) branches, respectively. VBX and SES groups represented 96 (54%) and 81 (46%) of the branches implanted. The celiac artery, superior mesenteric artery, right renal artery, and left renal artery received VBX as a bridging stent in 40%, 46.7%, 33.8%, and 32.2% respectively. The overall cohort survival rate was 78.5% at 24 months. There was no branch-related rupture or mortality. Primary patency at 24 months (VBX, 98.1%; SES, 98.6%; log-rank, P = .95), freedom from endoleak (VBX, 95.6%; SES, 98.6%; log-rank, P = .66), freedom from secondary intervention (VBX, 94.7%; SES, 98.1%; log-rank, P = .33), and freedom from branch instability (VBX, 95.6%; SES, 97.2%; log-rank, P = .77) were similar between groups. CONCLUSIONS: This initial experience with VBX stents demonstrated excellent primary patency and similarly low rates of branch-related complications and endoleaks, with no branch-related aortic rupture or death. Our results demonstrate that in a high-volume, experienced aortic center, the VBX stent is a safe and effective bridging stent option during branched endovascular aortic repair. Multicenter studies with a larger cohort and longer follow-up are necessary to validate these findings.

Ensuring equity, diversity, and inclusion in the Society for Vascular Surgery: A report of the Society for Vascular Surgery Task Force on Equity, Diversity, and Inclusion.

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.
