RESUMO
BACKGROUND: Isolated abdominal aortic dissection (IAAD) is a rare entity with poorly defined risk factors and wide variation in management. We set forth to compare patient characteristics, management, and outcomes of uncomplicated isolated abdominal aortic dissection (uIAAD) versus high risk and complicated isolated abdominal aortic dissection (hrcIAAD) to investigate whether these categories can be utilized to guide IAAD management and provide risk stratification for intervention. METHODS: Retrospective chart review was performed to identify all patients with spontaneous IAAD at a tertiary health care system between 1996 and 2022. Demographics, comorbidities, factors relating to initial presentation including imaging findings, and dissection outcomes including long-term all-cause mortality and aortic-related mortality from time of dissection to final available record were abstracted. IAAD demonstrating rupture or malperfusion were designated as complicated, those with aortic diameter greater than 4 cm on presentation or refractory pain were designated as high risk, and the remainder was designated as uIAAD. All variables were compared between hrcIAAD and uIAAD using Fisher's exact test, unpaired t-test, and Mann-Whitney U-test as appropriate. RESULTS: Over the study period, 74 patients presented with spontaneous IAAD (mean age 60 ± 16 years, 61% male) with postdissection follow-up records to an average of 6.8 ± 5.8 years. Of these, 76% presented with uIAAD versus 24% with hrcIAAD. hrcIAAD was diagnosed at a significantly younger age on average than uIAAD (52 ± 14 vs. 62 ± 16 years, P = 0.02), was less likely to present with concomitant hyperlipidemia (0% vs. 41%, P < 0.01), coronary artery disease (6% vs. 47%, P < 0.01), and prior smoking history (39% vs. 72%). hrcIAAD was more likely to present in patients with a genetic aortopathy (27% vs. 7%, P = 0.03). Hypertension was not significantly different between groups. Patients with hrcIAAD were significantly more likely to present with extension into iliac arteries compared to uIAAD (61% vs. 18%, P < 0.01). A much higher proportion of hrcIAAD required hospitalization compared to uIAAD (83% vs. 30%, P < 0.01) and operative intervention (67% vs. 7%, P < 0.01). While there was no significant difference in all-cause mortality between groups, there was a significant difference between aortic-related mortality which only occurred in those with hrcIAAD (28% vs. 0%, P < 0.01). CONCLUSIONS: Comparison of long-term outcomes suggests that hrcIAAD is associated with increased hospitalization and need for operative intervention compared to uIAAD. Significant differences in atherosclerotic risk factors and proportions of connective tissue disease history between patients who present with hrcIAAD and uIAAD suggest that differences in underlying etiology are largely responsible for whether IAAD progresses towards rupture or has a more benign course and should be considered in risk stratification to guide more specific and targeted management of IAAD.

INTRODUCTION: Engaging patients living with or at risk of aortic dissection via the Aortic Dissection Collaborative, physician education in vascular genetics was identified as a research priority. We surveyed vascular surgeons to characterize practice patterns, motivations, and barriers regarding aortopathy genetic testing. METHODS: An anonymous 27-question survey was distributed on social media platforms between November and December 2022. Domains included demographics, vascular genetic education, testing attitudes and utilization, and experience in treating patients with genetic vascular aortopathies. The analysis included summary statistics and unpaired t-test to compare responses by interest in incorporating testing and practice type. RESULTS: A total of 171 vascular surgeons from 15 countries responded to the survey (23% trainees). Over half received vascular genetics education during training (59%), and most (86%) were interested in incorporating genetic testing into their practice. Academic surgeons were more likely to have cared for a patient with a known genetic aortopathy over the past year than surgeons in hospital-based and private practices (83% vs. 56% vs. 27%; P < 0.01), to have ever made a referral to a medical geneticist (78% vs. 51% vs. 9%; P < 0.01), and have access to genetic counselors or geneticists (66% vs. 46% vs. 0%; P < 0.01). Barriers to genetic testing were rated as more significant by surgeons in nonacademic practices, with top barriers being insurance coverage of testing, cost of genetic testing, and access to genetic counselors. Evidence-based professional society guidelines were the strongest rated motivating factor for testing incorporation among respondents. CONCLUSIONS: Vascular surgeon attitudes are not major barriers to incorporating genetic testing for patients with aortopathies; however, practical challenges regarding genetic testing and counseling are barriers to implementation especially for vascular surgeons in nonacademic practices. Future efforts should focus on evidence-based society guidelines, continuing medical education to increase adoption, and facilitating access to genetic counseling.

OBJECTIVE: To assess whether outcomes of rupture repair differ by aortic repair history and determine the ideal approach for rupture repair in patients with previous aortic repair. METHODS: This retrospective review included all patients who underwent repair of a ruptured infrarenal abdominal aortic aneurysm from 2003 - 2021 recorded in the Vascular Quality Initiative (VQI) registry. Pre-operative characteristics and post-operative outcomes and long term survival were compared between patients with and without prior aortic repair. To assess the impact of open and endovascular approaches to rupture, a subgroup analysis was then performed among patients who ruptured after a prior infrarenal aortic repair. Univariable and adjusted analyses were performed to account for differences in patient characteristics and operative details. RESULTS: A total of 6 197 patients underwent rupture repair during the study period, including 337 (5.4%) with prior aortic repairs. Univariable analysis demonstrated an increased 30 day mortality rate in patients with prior repairs vs. without (42 vs. 36%; p = .034), and prior repair was associated with increased post-operative renal failure (35 vs. 21%; p < .001), respiratory complications (32 vs. 24%; p < .001), and wound complications (9 vs. 4%; p < .001). Following adjustment, all outcomes were similar with the exception of bowel ischaemia, which was decreased among patients with prior repair (OR 0.7, 95% CI 0.6 - 0.9). Subgroup analysis demonstrated that patients with a prior aortic repair history who underwent open rupture repair had increased odds for 30 day death (OR 1.3, 95% CI 1.2 - 1.7) and adverse secondary outcomes compared with those managed endovascularly. CONCLUSION: Prior infrarenal aortic repair was not independently associated with increased morbidity or mortality following rupture repair. Patients with a prior aortic repair history demonstrated statistically significantly higher mortality and morbidity when treated with an open repair compared with an endovascular approach. An endovascular first approach to rupture should be strongly encouraged whenever feasible in patients with prior aortic repair.

Giant carotid body tumors, defined as those >8 cm in size, are extremely rare. Definitive surgical management is a complex undertaking because these large tumors tend to have grown to envelop cranial nerves and the carotid artery, and few data exist regarding the long-term outcomes for these patients. We present the case of a patient with bilateral giant carotid body tumors who underwent staged embolization and excision of a >10-cm carotid body tumor. After 5 years of follow-up, we demonstrated that elective open repair can provide long-term symptomatic relief. We describe and illustrate the crucial steps and considerations regarding the excision of complex Shamblin type III carotid body tumors.
RESUMO
Vascular Ehlers-Danlos syndrome (VEDS) is rare, affecting an estimated 1 per 50,000 individuals, and is associated with abdominal aortic aneurysms (AAAs), among other arteriopathies. We present three patients with genetically confirmed VEDS who underwent successful open AAA surgical repair and demonstrate that elective open AAA repair with careful tissue manipulation is safe and feasible for patients with VEDS. These cases also demonstrate that the VEDS genotype is associated with the aortic tissue quality (genotype-surgical phenotype correlation), with the most friable tissue encountered in the patient with a large amino acid substitution and the least friable tissue in the patient with a null (haploinsufficiency) variant.
RESUMO
BACKGROUND: The first two Food and Drug Administration (FDA)-approved stents for treatment of iliofemoral vein obstruction, Boston Scientific's Vici and BD's Venovo venous stent systems, were both recalled in early 2021 within years of entering the market. Given the recent addition of patient issues as a publicly reported variable by the FDA Manufacturer and User Facility Device Experience (MAUDE) database, we set forth to analyze adverse event reports in MAUDE to better characterize issues reported for each system. METHODS: MAUDE was queried for all adverse event reports for brands "Vici" and "Venovo" from their respective US FDA market approval dates to August 19, 2021. Reported device issues, patient issues, and interventions performed for each adverse event were compiled and compared using Fisher's exact test. RESULTS: A total of 50 unique adverse event reports were compiled for the Vici system and 341 for the Venovo system. The most common device issue reported for the Vici system was migration (48% vs. 0%; P = 0.0001) versus activation failure in Venovo (85% vs. 4%; P = 0.0001). A significantly higher proportion of Venovo reports specified no patient complications or symptoms (90% vs. 26%; P = 0.0001), with no intervention performed (89% vs. 32%; P = 0.001). A significantly higher proportion of Vici devices were extracted (8% vs. 2%; P = 0.01), required use of a new device (26% vs. 5%; P = 0.0001), and required application of a second stent within the venous stent initially placed (28% vs. 2%; P = 0.0001). The rate of intervention with balloon expansion was not significantly different between the Vici and Venovo systems (6% vs. 2%; P = 0.08). CONCLUSIONS: While 2 venous stent systems were recalled simultaneously, significant differences exist between reported device issues in MAUDE and whether patient injury was involved and well described. Our data suggest that despite recent improvements to MAUDE reporting, additional standardization with specificity regarding patient issues and interventions is needed to assist vascular surgeons monitoring real-time adverse event trends for vascular devices.

Peripheral artery disease (PAD) impacts an estimated 230 million adults worldwide, including more than 9.5 million adults older than 40 years in the United States. PAD remains more underdiagnosed and undertreated than manifestations of atherosclerosis elsewhere in the body, such as coronary artery disease and cerebrovascular disease. Medical therapies benefit all patients with PAD, including those who are asymptomatic, as well as those with symptoms and advanced disease requiring intervention. Comprehensive medical management of PAD is based on tempering atherosclerotic disease processes and should include smoking cessation, exercise therapy, cholesterol reduction, antiplatelet, and/or anticoagulation therapy, as well as the application of peripheral vasodilators and blood pressure control, when indicated. For patients with intermittent claudication, supervised exercise therapy has been shown to provide similar or superior benefit compared with intervention and is recommended by major society guidelines as first-line therapy. In patients with advanced PAD requiring endovascular or surgical intervention, continued adherence to optimal medical therapy has been found to improve functional outcomes and decrease post-interventional mortality. Optimal medical management provides crucial benefits to patients with early, moderate, and advanced PAD and, once started, should be continued for life.

BACKGROUND: The Risk Analysis Index (RAI) frailty scoring system has recently undergone revision and external validation using the National Surgical Quality Improvement Program (NSQIP) database. We set forth to evaluate the association of RAI-rev ranges with outcomes following lower extremity surgical revascularization and verify equivalent applicability across genders. METHODS: All elective NSQIP Targeted Lower Extremity Open cases from 2015-2019 were divided by EMR-recorded gender. Aggregate demographics, perioperative factors, and 30-day outcomes were compared using unpaired t-test and Fisher's exact test. Adjusted odds-ratios (aOR) for each outcome were generated by applying a multivariate binary logistic regression model (IBM SPSSTM) for five-point RAI-rev score increments from 25-45 and a most-frail group with scores >45 with a non-frail reference of <25. Covariates included surgical indication, prior ipsilateral revascularization, graft utilization, dirty/infected wound, smoking, hypertension, diabetes, and steroid use. RESULTS: 8,155 cases included 2,498 (31%) performed in women who demonstrated slightly lower RAI-rev scores than men (22.1 ± 5.8 vs. 24.2 ± 5.1; P = 0.0001). Univariate trends demonstrated dose-dependent increases in frequency of most outcomes with rising frailty score ranges, most substantially regarding mortality (0.4% non-frail to 14.7% most-frail), disposition to skilled nursing facility (8% non-frail to 27% most-frail), and extended length of stay (16% non-frail to 44% most-frail). After adjusting for co-variates, patients with RAI-rev scores of 26-30 had aOR of 1.4 (95% CI: 1.2-1.6; P < 0.001), 1.9 (95% CI: 1.6-2.2; P < 0.001), and 2.4 (95% CI:1.3-4.4; P < 0.001) for extended stay, disposition to skilled nursing, and mortality respectively. Trends were similar across genders in both univariate and multivariate analyses. CONCLUSIONS: Mortality, extended stay, and increased rehabilitation needs after surgical revascularization were associated with higher RAI-rev score ranges in a dose dependent manner similarly across genders.

While recreational escape rooms have gained momentum across education and team training in multiple professions, few published escape room designs have been truly interprofessional. A major obstacle faced by educators and team leaders alike is the lack of any practical design framework for escape room development that is specific to meeting learning objectives. The COMET Framework (Context, Objectives, Materials, Execution, and Team Dynamics) was developed as a step-by-step approach to escape room design using general terminology and piloted in a one-hour workshop at a regional interprofessional conference. Surveys completed by participants suggest that application of the COMET framework increased understanding and confidence regarding escape room design regardless of prior experience with the format. The generality of the COMET framework may allow it to be utilized for team exercise design more broadly in the contexts of interprofessional training and faculty development.

BACKGROUND: Lower extremity bypass (LEB) revascularization can be performed under general (GA) or neuraxial anesthesia (NA). Studies show that the use of NA may decrease morbidity, 30-day mortality, and hospital length-of-stay (LOS). The goal of our analysis is to examine the differences in postsurgical outcomes following LEB between patients who undergo GA compared to NA in the Veteran Affairs Surgical Quality Improvement Program (VASQIP) database. METHODS: After IRB approval, the VASQIP database was assessed for patients who underwent LEB between 1998-2018. Only infrainguinal bypass procedures and anesthesia type classified as "general," "epidural," or "spinal" were included. The neuraxial cohort includes both spinal and epidural anesthesia patients. The Risk Analysis Index (RAI), a validated measure of frailty, was additionally calculated for each patient. Chi squared, paired t-test, and binary logistic regression were used to compare the cohorts. RESULTS: During this period, 22,960 veterans underwent LEB recorded in VASQIP. Compared to those who underwent surgery under GA, patients with procedures performed using NA were older (66.4 ± 9.6 years vs. 65.3 ± 9 years respectively; P <0.001) and more frail (average RAI score 25.7 ± 7.0 vs. 24.9 ± 6.7; P < 0.001). Operative time was shorter in the NA group (4.1 ± 1.7 hrs vs. 4.7 ± 3.0 hrs; P < 0.001) and fewer cases were emergent (1.55% vs. 4.13%; P <0.001). Patients in the GA group had higher rates of postoperative prolonged ileus (0.31% vs. 0.00%; P = 0.03), pneumonia (1.60% vs. 1.06%; P = 0.025), deep wound infection (2.67% vs. 2.61%; P = 0.01), sepsis (1.68% vs. 0.79%; P < 0.001), reintubation (1.80% vs. 1.30%) (P = 0.04),and number of packed red blood cell (pRBC) transfused intraoperatively (0.39 ± 1.21 units vs. 0.22 ± 0.79 units; P <0.001). There was no significant difference in rate of graft failure, return to the OR, myocardial infarction, death, or LOS. In regression analysis, those undergoing NA were less likely to require pRBC transfusion intraoperatively (OR: 0.43; 95% CI: 0.31-0.61; P < 0.001), however no other outcomes reached statistical significance. CONCLUSION: Although younger and less frail, veteran patients undergoing GA for lower extremity revascularization had higher rates of postoperative ileus, pneumonia, deep wound infection, sepsis, and need for transfusion as compared to those undergoing NA. There was no significant difference in the rate of other major complications, myocardial infarction, death or LOS. After adjustment, only intraoperative transfusion remained statistically significant, likely reflecting longer and more complex cases for those that undergo general anesthesia rather than the effect of anesthetic choice itself.

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.

OBJECTIVE: Surgical frailty and its assessment have become essential considerations in perioperative management for the modern aging surgical population. The risk analysis index is a validated frailty score that has been proven to predict short-term outcomes and long-term mortality in several surgical subspecialties and high-risk procedures. We examined the association of risk analysis index scores with postoperative outcomes in a retrospective nationwide database of patients who underwent lower extremity amputation in the Veterans Health Administration Health Care System. METHODS: The Veteran Affairs Surgical Quality Improvement Program data was queried across the Veteran Affairs Health Care System with institutional review board approval for lower extremity amputations. Records of above and below knee amputation, Current Procedural Terminology codes 27590, 27591, 27592, 27594, 27596 and 27880, 27881, 27882, 27884, and 27886, respectively, from 1999 to 2018 were obtained. Incomplete and traumatic entries were removed. Risk Analysis Index score was calculated from preoperative variables and patients were separated into five score cohorts (≤15, 16-25, 26-35, 36-45, ≥46). The χ2 test and analysis of variance were used to compare the cohorts. Forward binary logistic regression modeling was used to determine covariate-adjusted odds ratios for outcomes in each cohort (SPSS software; version 25, IBM Corp). RESULTS: A total of 47,197 patients (98.9% male) with an average age of 66.4 ± 10.6 years underwent nontraumatic lower extremity amputation, including 27,098 below knee and 20,099 above knee amputations, during the study period. Frailty was associated with increased rates of deep vein thrombosis, sepsis, cardiac arrest, myocardial infarction, pneumonia, intubation for more than 48 hours, pulmonary embolism, reintubation, acute kidney injury, renal failure, increased length of stay, overall complications, and death. Increases in the frailty score were associated with up to three times the likelihood for the occurrence of a postoperative complication and up to 32 times likelihood to perish within 30 days than those with low frailty scores. CONCLUSIONS: Risk analysis index assessment of frailty was found to be associated with several postoperative outcomes in a dose-dependent manner in patients undergoing lower extremity amputation in the Veterans Health Care System, with higher scores associated with higher rates of death and major cardiac (myocardial infarction, cardiac arrest), pulmonary (pneumonia, failure to wean vent, reintubation), and renal (renal insufficiency, renal failure) complications. We recommend the use of risk analysis index score as a frailty screening tool for patients undergoing lower extremity amputation to enable providers to adequately inform and counsel patients regarding potential significant risks.

BACKGROUND: Increasing access to safe, timely, and affordable acute care in low- and middle-income countries is a worldwide priority. Longitudinal curricula on systems of acute care have not been previously described. OBJECTIVES: The authors aimed to develop a novel four-year longitudinal curriculum for medical students addressing systems development across multiple acute care specialties. METHODS: The authors followed Kern's six-step framework for curriculum design. After review of literature, a group of medical students and school of medicine faculty conducted a targeted needs assessment. Foundational goals and objectives were adapted from the 39 interprofessional global health competencies by the Consortium of Universities for Global Health. Educational strategies include didactic sessions, workshops, journal clubs, preceptorships, and community outreach. Clinical years include specialty-specific emphases, guided junior-level discussions, and a capstone project. Yearly SWOT and Kirkpatrick model analyses served as program evaluation. FINDINGS: The Curriculum Council approved the program in July 2019. During the first cycle, the program matriculated 30 students from classes of 2023 (14) and 2022 (16). The first year produced 11 interactive sessions, 6 journal clubs, and 10 seminars led by 31 faculty and guest speakers; 29/30 students completed requirements; 87 evaluations reflected 4.57/5 content satisfaction and 4.73/5 instructor satisfaction. The 2023 cohort reported improved understanding of session objectives (3.13/5 vs. 3.82/5, p = 0.03). Free-text feedback led to implementation of pre-reading standardization and activity outlines. CONCLUSION: The Program was well-received and successfully implemented. It meets the needs of graduating medical students interested in leading global health work. This novel student-faculty collaborative model could be applied at other institutions seeking to provide students with a foundation in global acute care.

OBJECTIVE: The Food and Drug Administration recently approved two percutaneous arteriovenous fistula creation systems: the Ellipsys vascular access (EL) system and WavelinQ EndoAVF (WQ) system. Although the initial clinical trials of each system have demonstrated a high success rate, little detail on anatomic suitability was provided. We sought to determine the real-world applicability of the EL and WQ systems by studying them in a single representative cohort. METHODS: All patients receiving a first-time arteriovenous access consultation at a single Veterans Affairs institution underwent extensive vein mapping of the bilateral upper extremities. Anatomic suitability was assessed in accordance with the manufacturer's instructions for use (IFU), and clinical usability was determined using additional published anatomic guidelines. The suitability for radiocephalic fistula (RCF) creation was also assessed. To estimate how often these systems would be used in practice, a clinical algorithm was created, with a preference for RCF creation, followed by percutaneous arteriovenous fistula (pAVF) creation, surgical fistula creation at the elbow, and, finally, graft placement. RESULTS: During the study period, 116 upper extremities were measured in 58 male patients. Per the IFU, the rate of extremity suitability was 93% and 52% for the WQ and EL systems, respectively (P < .0001). In the same population, 32% of the extremities had acceptable anatomy for RCF creation. The overall clinical usability of these systems using more recent published guidelines was 55% for the WQ system and 44% for the EL system (P = .09). The usability of both pAVF systems was most limited by the size of the deep perforating cubital vein. The proximity of the antecubital perforator vein and proximal radial artery additionally limited EL usability. Based on the clinical algorithm, initial access creation would have been RCF creation for 31% of the cohort, followed by the WQ (32%), the EL (23%), surgical fistula creation at the elbow (18%), and graft placement (17%). CONCLUSIONS: Anatomic suitability was greater for WQ than for EL when considering only the IFU. Once the full requirements for pAVF creation were considered, we found no significant differences in usability between the two systems. Anatomic analysis showed that pAVF creation can constitute a substantial part of a hemodialysis access practice.

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.

Systemic lupus erythematosus (SLE) is a multi-organ autoimmune disorder with a prominent genetic component. Individuals of African ancestry (AA) experience the disease more severely and with an increased co-morbidity burden compared to European ancestry (EA) populations. We hypothesize that the disparities in disease prevalence, activity, and response to standard medications between AA and EA populations is partially conferred by genomic influences on biological pathways. To address this, we applied a comprehensive approach to identify all genes predicted from SNP-associated risk loci detected with the Immunochip. By combining genes predicted via eQTL analysis, as well as those predicted from base-pair changes in intergenic enhancer sites, coding-region variants, and SNP-gene proximity, we were able to identify 1,731 potential ancestry-specific and trans-ancestry genetic drivers of SLE. Gene associations were linked to upstream and downstream regulators using connectivity mapping, and predicted biological pathways were mined for candidate drug targets. Examination of trans-ancestral pathways reflect the well-defined role for interferons in SLE and revealed pathways associated with tissue repair and remodeling. EA-dominant genetic drivers were more often associated with innate immune and myeloid cell function pathways, whereas AA-dominant pathways mirror clinical findings in AA subjects, suggesting disease progression is driven by aberrant B cell activity accompanied by ER stress and metabolic dysfunction. Finally, potential ancestry-specific and non-specific drug candidates were identified. The integration of all SLE SNP-predicted genes into functional pathways revealed critical molecular pathways representative of each population, underscoring the influence of ancestry on disease mechanism and also providing key insight for therapeutic selection.

INTRODUCTION: In response to the Coronavirus 2019 (COVID-19) pandemic, vascular surgeons in the Veteran Affairs Health Care System have been undertaking only essential cases, such as advanced critical limb ischemia. Surgical risk assessment in these patients is often complex, considers all factors known to impact short- and long-term outcomes, and the additional risk that COVID-19 infection could convey in this patient population is unknown. The European Centre for Disease Prevention and Control (ECDC) published risk factors (ECDC-RF) implicated in increased COVID-19 hospitalization and case-fatality which have been further evidenced by initial reports from the United States Centers for Disease Control and Prevention. CDC reports additionally indicate that African American (AA) patients have incurred disparate infection outcomes in the United States. We set forth to survey the Veterans Affairs Surgical Quality Improvement Program (VASQIP) database over a nearly 20 year span to inform ongoing risk assessment with an estimation of the prevalence of ECDC-RF in our veteran critical limb ischemia population and investigate whether an increased COVID-19 comorbidity burden exists for AA veterans presenting for major non-traumatic amputation. MATERIALS AND METHODS: The VASQIP database was queried for all above knee amputation (AKA) and below knee amputation (BKA) completed 1999-2018 after IRB approval (MIRB:#02507). Patient race and ECDC-RF including male gender, age > 60 years, smoking status, hypertension, diabetes, chronic obstructive pulmonary disease, cancer, and cardiovascular disease were recorded from preoperative patient history. AKA and BKA cohorts were compared via χ2-test with Yates correction or unpaired t-test and a subgroup analysis was conducted between AA and all other race patients for COVID-19 comorbidities in each cohort. RESULTS: VASQIP query returned 50,083 total entries. Average age was 65.1 ± 10.4 years and 68.2 ± 10.5 years for BKA and AKA cohorts, respectively, (P < .0001) and nearly all patients were male (99%). At least one ECDC-RF comorbidity was present in 25,526 (88.7%) of BKA and 17,558 (82.4%) of AKA patients (P < .0001). AA BKA patients were significantly more likely than non-AA BKA patients to present with at least one ECDC-RF comorbidity (P = .01). CONCLUSIONS: According to a large national Veterans Affairs database, there are high rates of ECDC-RF in veteran amputees. During the present crisis, management of these patients should incorporate telehealth, expedient discharge, and ongoing COVID-19 transmission precautions.
