Abstract
OBJECTIVE The COVID-19 pandemic has drastically altered the medical landscape. Various strategies have been employed to preserve hospital beds, personal protective equipment, and other resources to accommodate the surges of COVID-19 positive patients, hospital overcapacities, and staffing shortages. This has had a dramatic effect on vascular surgical practice. The objective of this study is to analyze the impact of the COVID-19 pandemic on surgical delays and adverse outcomes for patients with chronic venous disease scheduled to undergo elective operations. METHODS The Vascular Surgery COVID-19 Collaborative (VASCC) was founded in March 2020 to evaluate the outcomes of patients with vascular disease whose operations were delayed. Modules were developed by vascular surgeon working groups and tested before implementation. A data analysis of outcomes of patients with chronic venous disease whose surgeries were postponed during the COVID-19 pandemic from March 2020 through February 2021 was performed for this study. RESULTS A total of 150 patients from 12 institutions in the United States were included in the study. Indications for venous intervention were: 85.3% varicose veins, 10.7% varicose veins with venous ulceration, and 4.0% lipodermatosclerosis. One hundred two surgeries had successfully been completed at the time of data entry. The average length of the delay was 91 days, with a median of 78 days. Delays for venous ulceration procedures ranged from 38 to 208 days. No patients required an emergent intervention due to their venous disease, and no patients experienced major adverse events following their delayed surgeries. CONCLUSIONS Interventions may be safely delayed for patients with venous disease requiring elective surgical intervention during the COVID-19 pandemic. This finding supports the American College of Surgeons' recommendations for the management of elective vascular surgical procedures. Office-based labs may be safe locations for continued treatment when resources are limited. Although the interventions can be safely postponed, the negative impact on quality of life warrants further investigation.

Abstract
INTRODUCTION Peripheral artery disease (PAD) is associated with an increased likelihood of delayed or non-healing of a diabetes-related foot ulcer, gangrene, and amputation. The selection of the most effective surgical technique for revascularisation of the lower limb in this population is challenging and there is a lack of conclusive evidence to support the choice of intervention. This systematic review aimed to determine, in people with diabetes and tissue loss, if direct revascularisation is superior to indirect revascularisation and if endovascular revascularisation is superior to open revascularisation for the outcomes of wound healing, minor or major amputation, and adverse events including mortality. METHODS Title and abstract searches of Medline, Embase, PubMed, and EBSCO were conducted from 1980 to 30th November 2022. Cohort and case-control studies and randomised controlled trials reporting comparative outcomes of direct (angiosome) revascularisation (DR) and indirect revascularisation (IR) or the comparative outcomes of endovascular revascularisation and open or hybrid revascularisation for the outcomes of healing, minor amputation, and major amputation in people with diabetes, PAD and tissue loss (including foot ulcer and/or gangrene) were eligible. Methodological quality was assessed using the Cochrane risk-of-bias tool for randomised trials, the ROBINS-I tool for non-randomised studies, and Newcastle-Ottawa Scale for observational and cohort studies where details regarding the allocation to intervention groups were not provided. RESULTS From a total 7086 abstracts retrieved, 26 studies met the inclusion criteria for the comparison of direct angiosome revascularisation (DR) and indirect revascularisation (IR), and 11 studies met the inclusion criteria for the comparison of endovascular and open revascularisation. One study was included in both comparisons. Of the included studies, 35 were observational (31 retrospective and 4 prospective cohorts) and 1 was a randomised controlled trial. Cohort study quality was variable and generally low, with common sources of bias related to heterogeneous participant populations and interventions and lack of reporting of or adjusting for confounding factors. The randomised controlled trial had a low risk of bias. For studies of DR and IR, results were variable, and it is uncertain if one technique is superior to the other for healing, prevention of minor or major amputation, or mortality. However, the majority of studies reported that a greater proportion of participants receiving DR healed compared with IR, and that IR with collaterals may have similar outcomes to DR for wound healing. For patients with diabetes, infrainguinal PAD, and an adequate great saphenous vein available for use as a bypass conduit who were deemed suitable for either surgical procedure, an open revascularisation first approach was superior to endovascular therapy to prevent a major adverse limb event or death (Hazard Ratio: 0.72; 95% CI 0.61-0.86). For other studies of open and endovascular approaches, there was generally no difference in outcomes between the interventions. CONCLUSIONS The majority of available evidence for the effectiveness of DR and IR and open and endovascular revascularisation for wound healing and prevention of minor and major amputation and adverse events including mortality in people with diabetes, PAD and tissue loss is inconclusive, and the certainty of evidence is very low. Data from one high quality randomised controlled trial supports the use of open over endovascular revascularisation to prevent a major limb event and death in people with diabetes, infrainguinal disease and tissue loss who have an adequate great saphenous vein available and who are deemed suitable for either approach.

Abstract
Thoracic outlet syndrome (TOS) is a rare anatomic condition caused by compression of neurovascular structures as they traverse the thoracic outlet. Depending on the primary structure affected by this spatial narrowing, patients present with one of three types of TOS-venous TOS, arterial TOS, or neurogenic TOS. Compression of the subclavian vein, subclavian artery, or brachial plexus leads to a constellation of symptoms, including venous thrombosis, with associated discomfort and swelling; upper extremity ischemia; and chronic pain due to brachial plexopathy. Standard textbooks have reported a predominance of females patients in the TOS population, with females comprising 70%. However, there have been few comparative studies of sex differences in presentation, treatment, and outcomes for the various types of TOS.

Abstract
BACKGROUND Objective measures of perfusion such as an ankle-brachial index (ABI) and toe pressure remain important in prognosticating wound healing. However, the use of ABI is limited in patients with incompressible vessels and toe pressure may not be comparable across patients. While a toe arm index (TAI) may be of value in this setting, its role as clinical indicator of perfusion for healing in patients with lower-extremity wounds has not been well established. METHODS A retrospective review was performed of all vascular patients with lower-extremity wounds that underwent peripheral vascular intervention between 2014-2019. Data regarding patient demographics, comorbidities, TAI, ABI, toe pressures, and the wound, ischemia, and foot infection (WIfI) score were collected. Associations between patient variables and wound healing at various time points were evaluated. RESULTS A total of 173 patients (67.7 ± 10.9 years; 71.1% male) were identified with lower-extremity wounds. Most patients underwent endovascular intervention (77.5%). Patients were followed for a median of 416 (IQR 129-900) days. Mean postoperative TAI was 0.35 ± 0.19 and mean WIfI score was 2.60 ± 1.17. Nine percent (15) of patients healed within 1 month, 44.8% (69) healed within 6 months, and 65.5% (97) healed within 1 year of revascularization without need for major amputation. Those that healed within 1 year without any major amputation did not differ from those that did not heal based on age, gender, race, comorbidities, periprocedural medications, or procedures performed. However, patients that healed without major amputation had a higher postoperative TAI (0.38 vs. 0.30, P = 0.02), higher toe pressure (53 vs. 40 mm Hg, P = 0.004), and lower WIfI score (2.26 vs. 3.12, P < 0.001). Patients that healed with 1 year without requiring any amputation had similar associations with postoperative TAI, toe pressure, and WIfI. Additionally, they were more likely to be White (P = 0.019) and have an open surgical procedure (P < 0.001) and less likely to have chronic kidney disease (P = 0.001) or diabetes (P = 0.008). A Youden index was calculated and identified a TAI value of 0.30 that optimized sensitivity and specificity for wound healing. The area under the curve for TAI as a predictor of wound healing was 0.62. CONCLUSIONS Higher postoperative TAI is associated with higher odds of wound healing without need for major amputation. Toe arm index is therefore a useful tool to identify patients with adequate arterial perfusion to heal lower-extremity wounds. However, the area under the curve is poor for TAI when used as a sole predictor of wound healing potential suggesting that TAI should be one of multiple factors to considered when prognosticating wound healing potential.

Abstract
Implantable vascular devices are widely used in clinical treatments for various vascular diseases. However, current approved clinical implantable vascular devices generally have high failure rates primarily due to their surface lacking inherent functional endothelium. Here, inspired by the pathological mechanisms of vascular device failure and physiological functions of native endothelium, we developed a new generation of bioactive parylene (poly(p-xylylene))-based conformal coating to address these challenges of the vascular devices. This coating used a polyethylene glycol (PEG) linker to introduce an endothelial progenitor cell (EPC) specific binding ligand LXW7 (cGRGDdvc) onto the vascular devices for preventing platelet adhesion and selectively capturing endogenous EPCs. Also, we confirmed the long-term stability and function of this coating in human serum. Using two vascular disease-related large animal models, a porcine carotid artery interposition model and a porcine carotid artery-jugular vein arteriovenous graft model, we demonstrated that this coating enabled rapid generation of self-renewable "living" endothelium on the blood contacting surface of the expanded polytetrafluoroethylene (ePTFE) grafts after implantation. We expect this easy-to-apply conformal coating will present a promising avenue to engineer surface properties of "off-the-shelf" implantable vascular devices for long-lasting performance in the clinical settings.

Abstract
BACKGROUND Access to care plays a critical role in limb salvage in chronic limb-threatening ischemia (CLTI). A "medical desert" describes a community lacking access to medical necessities, resulting in increased morbidity and mortality. We sought to describe vascular deserts, which we defined as regions with decreased access to specialty care. METHODS All California providers performing vascular surgery procedures were identified through online provider and health care facility searches. Facility participation in the Society for Vascular Surgery (SVS) Vascular Quality Initiative (VQI) lower extremity bypass (LEB) and peripheral vascular intervention (PVI) modules was also determined. Addresses were geocoded with a 30-mile surrounding buffer using ArcGIS (Geographic information systems), creating maps based on care type, including all providers performing vascular procedures, board-certified vascular surgeons, and facilities participating in VQI modules. Public census data overlayed on the maps demonstrated population composition in desert versus nondesert regions. Subsequently, data from the Healthy Places Index (HPI) was overlayed, providing data regarding 25 social factors, comprising an overall HPI score and percent, with lower scores corresponding to poorer health and outcomes. RESULTS Maps depicting care regions demonstrated decreased provider coverage with increasing specialty care, with the VQI provider map showing the most prominent "desert" regions. When comparing nondesert versus desert regions by care type, demographics including race, the percentage of the population 200% below the poverty line, and the rate of uninsured residents were described. Social determinants of health were then described for desert and nondesert regions by care type, including the HPI percentage and specific domain factors. The percentage of uninsured residents was significant only in the desert and nondesert areas served by board-certified vascular surgeons (19.6 vs. 16.8%, P < 0.001). The mean HPI percentile was significantly lower in board-certified provider and VQI facility deserts than nondeserts (50.48% vs. 40.65%, P < 0.001 and 52.68% vs. 43.12%, P < 0.001, respectively). The economic and education factor percentiles were significantly lower in all desert populations, while the housing, social, and pollution factors were significantly higher in nondesert regions. Health care access, transportation, and neighborhood factor percentiles were significantly lower in board-certified and VQI facility deserts than in the nondesert areas. CONCLUSIONS Access to vascular care plays a significant role in limb salvage. Through mapping vascular deserts, patient demographics, and social factors in desert regions are better understood, and areas that would benefit most from targeted outreach and limb preservation programs for CLTI are identified.

Abstract
Thoracic outlet syndrome (TOS) is a disease pattern that involves compression of neurologic venous or arterial structures as they pass through the thoracic outlet. TOS was first described as a vascular complication arising from the presence of a cervical rib. Over time, a better understanding of TOS has led to its wide range of presenting symptoms being divided into three distinct groups: arterial, venous, and neurogenic. Of the known cases, the current estimates of the incidence of neurogenic TOS, venous TOS, and arterial TOS are 95%, 3%, and 1%, respectively. The different types of TOS have completely different presentations, requiring expertise in the diagnosis, management, and treatment unique to each. We present our evaluation, diagnosis, and management method of TOS patients, with specific attention paid to the transaxillary approach.

Abstract
OBJECTIVE Utilization of evidence-based specialty guidelines is low in primary care settings. Early use of ankle-brachial index (ABI) testing and a validated wound classification system allows prompt referral of patients for specialty care. We implemented a program to teach providers ABI testing and the use of the Wound, Ischemia, and foot Infection (WIfI) classification tool. Here, we report program outcomes and provider perceptions. METHODS Physicians and non-physicians from wound care centers, nursing and physician education programs, primary care offices, and federally qualified health centers were invited to participate in the educational program teaching ABI testing and the use of the WIfI tool. Pretest and posttest responses and intention to use content in the future were assessed with descriptive statistics. RESULTS A total of 101 subjects completed the ABI module, and 84 indicated their occupation (59 physicians, 25 non-physicians). Seventy-nine subjects completed the WIfI module, and 89% indicated their occupation (50 physicians, 20 non-physicians). Physicians had lower pre-test knowledge scores for the ABI module than non-physicians (mean scores of 7.9 and 8.2, respectively). Both groups had improved knowledge scores on the post-test (physicians, 13.4; non-physicians, 13.8; P < .001). Non-physicians in practice longer than 10 years at wound care centers had the lowest baseline knowledge scores, whereas physicians in practice for over 10 years had the highest. In the ABI module, the largest knowledge gap included accurately calculating the ABI, followed by the correct use of the Doppler, and management of incompressible vessels. For the WIfI module, providers struggled to accurately score patients based on wound classification. The greatest barriers to the implementation of ABI testing were the availability of trained personnel, followed by limited time for testing. Barriers to the use of the WIfI tool for physicians included lack of time and national guideline support. For non-physicians, the most notable barrier was a lack of training. CONCLUSIONS Provider understanding of ABI and WIfI tools are limited in wound care centers, primary care offices, and federally qualified health centers. Further barriers include a lack of training in the use of tools, limited potential for point-of-care testing reimbursement, and insufficient dissemination of WIfI guidelines. Such barriers discourage widespread adoption and result in delayed diagnosis of arterial insufficiency.

Abstract
Chronic limb-threatening ischemia represents the morbid end stage of severe peripheral artery disease, with significant impact on patient quality of life. Early diagnosis of arterial insufficiency and referral for vascular intervention are essential for successful limb salvage. Disparate outcomes have been reported among patients residing in rural areas due to decreased access to care. Remote telemedicine outreach programs represent an opportunity to improve access to care in these rural communities. Establishment of a telehealth program requires identification of communities most in need of specialty care. After locating an ideal site, collaboration with local providers is necessary to develop a program that meets the specific needs of providers and patients. Surgeon guidance in development of screening and management algorithms ensures that patients obtain care reliably and with adjustments as needed to suit the referring provider, the patient, and the specialist. Telehealth evaluations can limit the financial burden associated with travel, while ensuring access to higher levels of care than are available in the patients' immediate area. Multiple barriers to telehealth exist. These include limited reimbursement, local provider resistance to new referral patterns, lack of in-person interaction and evaluation, and the inability to do a physical examination. Improved reimbursement models have made telehealth feasible, although care must be taken to ensure that practice patterns complement existing resources and are designed in a way that omits the need for in-person evaluation until the time of specialist intervention. Telemedicine is an underused tool in the arsenal of vascular surgeons. Targeted telehealth programs aid in increasing patient access to expert-level care, thereby improving health disparities that exist in rural populations.

Abstract
Objectives Determine patient and provider perspectives on widespread rapid telemedicine implementation, understand the key components of a surgical telemedicine visit and identify factors that affect future telemedicine use. Summary of background data Compared to other specialties, the field of surgery heretofore has had limited adoption of telemedicine. During the COVID-19 pandemic Healthcare, including the surgical specialties, saw new widespread use of telemedicine. Methods We conducted a prospective cohort study during the COVID-19 California stay-at-home and physical distancing executive orders. Utilization data were collected from clinics and compared to usage data during the same time 1 year later. All patients and providers who participated in a telemedicine visit during the study period were asked to complete a survey after each encounter and the surveys were analyzed for trends in opinions on future use by stakeholders. Results Over the 10-week period, the median percentage of telemedicine visits per clinic was 33% (17%-51%) which peaked 3 weeks into implementation. One hundred and ninety-one patients (48% women) with a median age of 64 years (IQR 53-73) completed the patient survey. Patients were first-time participants in telemedicine in 41% (n = 79) of visits. Fifty-seven percent (n = 45) of first-time users preferred that future visits be in-person versus 31% of prior users (p = 0.007). The median travel time from home to the clinic was 40 min (IQR = 20-90). Patients with longer travel times were not more likely to use telemedicine in the future (61% with longer travel vs. 53% shorter, p = 0.11). From the 148 provider responses, 90% of the visits providers were able to create a definitive plan with the telemedicine visit. A physical exam was determined not to be needed in 45% of the visits. An attempt at any physical exam was not performed in 84% of routine follow-up or new-patient visits, compared to 53% of post-op visits (p = 0.001). Conclusion Telemedicine is a viable ambulatory visit option for surgical specialists and their patients. During rapid telemedicine deployment, travel distance did not correlate with increased use of telemedicine, and in-person visits are still preferred. However, nearly half of all visits did not need a physical exam, which favors telemedicine use.

Abstract
OBJECTIVE The optimal revascularization modality following complete resection of aortic graft infection (AGI) without enteric involvement remains unclear. The purpose of this investigation is to determine the revascularization approach associated with the lowest morbidity and mortality using real-world data in patients undergoing complete excision of AGI. METHODS A retrospective, multi-institutional study of AGI from 2002-2014 was performed using a standardized database. Baseline demographics, comorbidities, and perioperative variables were recorded. The primary outcome was infection-free survival. Descriptive statistics, Kaplan-Meier survival analysis, and univariate and multivariable analyses were performed. RESULTS 241 patients at 34 institutions from 7 countries presented with AGI during the study period (median age 68 years; 75% male). The initial aortic procedures that resulted in AGI were 172 surgical grafts (71%) and 66 endografts (27%) and 3 unknown (2%). 172 (71%) of the patients underwent complete excision of infected aortic graft material followed by in situ (in-line) bypass (ISB), including antibiotic-treated prosthetic graft (35%), autogenous femoral vein (NAIS) (24%), and cryopreserved allograft (41%). 69 patients (29%) underwent extra-anatomic bypass (EAB). Overall median Kaplan-Meier (KM) estimated survival was 5.8 years. Perioperative mortality was 16%. When stratified by ISB versus EAB, there was a significant difference in KM estimated infection-free survival (2910 days, IQR 391, 3771 versus 180 days, IQR 27, 3750 days; p<0.001). There were otherwise no significant differences in presentation, comorbidities, nor perioperative variables. Multivariable Cox regression showed lower infection-free survival among patients with EAB (HR 2.4, 95% CI 1.6-3.6; p<0.001), polymicrobial infection (HR 2.2, 95% CI 1.4-3.5; p=0.001), MRSA infection (HR 1.7, 95% CI 1.1-2.7; p=0.02), as well as the protective effect of omental/muscle flap coverage (HR 0.59, 95% CI 0.37-0.92; p=0.02). CONCLUSIONS After complete resection of AGI, perioperative mortality is 16% and median overall survival is 5.8 years. EAB is associated with nearly a two-and-half fold higher re-infection/mortality compared to ISB. Omental and/or muscle flap coverage of the repair appear protective.

Abstract
BACKGROUND Patients with lower extremity wounds from diabetes mellitus or peripheral artery disease (PAD) have a risk of amputation as high as 25%. In patients with arterial disease, revascularization decreases the risk of amputation. We aimed to determine if the early assessment of arterial perfusion correlates with the risk of amputation. METHODS We retrospectively reviewed patients referred to the vascular clinic over 18 months with Rutherford Grade 5 and 6 chronic limb-threatening ischemia to determine if patients had a pulse exam done at the time the wound was identified and when ankle brachial index (ABI) testing to evaluate perfusion was performed. Kaplan Meier analysis was used to determine if the timing of ABI testing affected the time to revascularization, wound healing, and risk of amputation. RESULTS Ninety-three patients with lower extremity wounds were identified. Of these, 59 patients (63%) did not have a pulse exam performed by their primary care provider when the wound was identified. Patients were classified by when they underwent ankle brachial index testing to assess arterial perfusion. Twenty-four had early ABI (<30 days) testing, with the remaining 69 patients having late ABI testing. Patients in the early ABI group were more likely to have a pulse exam done by their PCP than those in the late group, 12 (50%) vs. 22 (32%), P = 0.03. Early ABI patients had a quicker time to vascular referral (13 days vs. 91 days, P < 0.001). Early ABI patients also had quicker times to wound healing than those in the late group (117 days vs. 287 days, P < 0.001). Finally, patients that underwent early ABI were less likely to require amputation (Fig. 1), although this did not reach statistical significance (P = 0.07). CONCLUSIONS Early ABI testing expedites specialty referral and time to revascularization. It can decrease the time to wound healing. Larger cohort studies are needed to determine the overall effect of early ABI testing to decrease amputation rates.

Abstract
OBJECTIVE ACGME work hour restrictions and decreasing resident case volumes have led to concern regarding competence of surgical residency graduates. Early operative experience is an important component of surgical education, providing a foundation for further learning. Intern year represents an opportunity for increased exposure. We sought to examine factors impacting intern perceptions and participation in the operating room. METHODS This cross-sectional retrospective study evaluated the experience of interns from June 2019 through June 2020. Data was collected from nursing operative case logs, self-reported ACGME intern case logs, and an intern survey from the 2019 to 2020 academic year for 3 surgical services at a large academic institution. The primary endpoint was intern presence in operative cases and perceived experience. SETTING University of California, Davis Medical Center, a large academic training institution and tertiary referral center located in Sacramento, California. PARTICIPANTS A total of 31 interns comprised the 2019 to 2020 training cohort, including preliminary, categorical general surgery, and integrated subspecialty residents classified as intern by the institution, regardless of postgraduate training year. RESULTS Interns were present in 945 (46%) of 2054 operative cases. Multivariable analysis indicated the presence of an APP (OR 1.68, 95% C.I. 1.34-2.10, p = 0.00) and a female attending (OR 1.30, 95% C.I. 1.07-1.58, p = 0.01) increased the likelihood of intern participation, while presence of an upper level resident decreased the likelihood (OR 0.35, 95% C.I. 0.22-0.57, p = 0.00). Interns participated in more cases later in the year compared to earlier (43% vs 59%, Z = 4.72, p = < 0.001). Surveys demonstrated participation was associated with encouragement by faculty and senior residents and a positive learning environment. Competing floor and clinic responsibilities negatively impacted participation (p < 0.001). CONCLUSIONS Intern operative experience can be robust in the setting of ACGME work hour guidelines. Identified factors represent possible areas for improvement in service organization.

Abstract
The use of social media (SoMe) in medicine has demonstrated the ability to advance networking among clinicians and other healthcare staff, disseminate research, increase access to up-to-date information, and inform and engage medical trainees and the public at-large. With increasing SoMe use by vascular surgeons and other vascular specialists, it is important to uphold core tenets of our commitment to our patients by protecting their privacy, encouraging appropriate consent and use of any patient-related imagery, and disclosing relevant conflicts of interest. Additionally, we recognize the potential for negative interactions online regarding differing opinions on optimal treatment options for patients. The Society for Vascular Surgery (SVS) is committed to supporting appropriate and effective use of SoMe content that is honest, well-informed, and accurate. The Young Surgeons Committee of the SVS convened a diverse writing group of SVS members to help guide novice as well as veteran SoMe users on best practices for advancing medical knowledge-sharing in an online environment. These recommendations are presented here with the goal of elevating patient privacy and physician transparency, while also offering support and resources for infrequent SoMe users to increase their engagement with each other in new, virtual formats.

Abstract
Objectives: Limited data support the use of fasciotomies in acute limb ischemia (ALI) in patients with isolated arterial occlusion. This study describes an experience in which fasciotomies are not regularly performed post-revascularization. Methods: Using International Classification of Diseases, Ninth and Tenth Edition codes, patients presenting to the University of California Davis Medical Center between January 2003 and July 2018 with ALI, excluding those with traumatic injuries were identified. The primary outcome was major amputation, and the secondary outcome was foot drop. Additionally, the characteristics of those patients in each category of ischemic severity excluding those with grade 3 ischemia were summarized. Results: Of the 253 patients identified, revascularization was successful in 230 patients with 11 total fasciotomies performed. One hundred thirty-five patients were Rutherford Class 1/2A and 95 were 2B. In those with 1/2A ischemia, 134 (102 had >6 hours of symptoms) did not undergo fasciotomy with only one amputation occurring in this group. In those with 2B ischemia, 65 had >6 hours of symptoms; 58 did not undergo fasciotomy with 4 major amputations. In the 30 patients with ≤6 hours of ischemic symptoms, 27 did not undergo fasciotomy with 1 major amputation occurring in this group. There were no amputations in those patients who underwent fasciotomies. Additionally, there were 14 patients with a foot drop, of which 11 were in patients with 2B ischemia without fasciotomy. Conclusions: The data suggest that regardless of ischemic duration, 1/2A patients may not need fasciotomies, while those patients with 2B ischemia may benefit.

Abstract
BACKGROUND AND OBJECTIVES Although arterial involvement for advanced tumors is rare, vascular resection may be indicated to achieve complete tumor resection. Given the potential morbidity of this approach, we sought to evaluate perioperative outcomes, vascular graft patency, and survival among patients undergoing tumor excision with en bloc arterial resection and reconstruction. METHODS From 2010 to 2020, we identified nine patients with tumors encasing or extensively abutting major arterial structures for whom en bloc arterial resection and reconstruction was performed. RESULTS Mean age was 53 ± 20 years, and 89% were females. Diagnoses were primary sarcomas (5), recurrent gynecologic carcinomas (3), and benign retroperitoneal fibrosis (1). Tumors involved the infrarenal aorta (2), iliac arteries (6), and superficial femoral artery (1). Three patients (33%) had severe perioperative morbidity (Grade III + ) with no mortality. At a median follow-up of 23 months, eight patients (89%) had primary graft patency, and five patients (56%) had no evidence of disease. CONCLUSIONS Arterial resection and reconstruction as part of the multimodality treatment of regionally advanced tumors is associated with acceptable short- and long-term outcomes, including excellent graft patency. In appropriately selected patients, involvement of major arterial structures should not be viewed as a contraindication to attempted curative surgery.

Abstract
OBJECTIVE Medical schools and surgical residencies have seen an increase in the proportion of female matriculants, with 30% of current vascular surgery trainees being women over the past decade. There is widespread focus on increasing diversity in medicine and surgery in an effort to provide optimal quality of patient care and the advancement of science. The presence of gender diversity and opportunities to identify with women in leadership positions positively correlates with women choosing to enter traditionally male-dominated fields. The purpose of this study was to evaluate the representation of women in regional and national vascular surgical societies over the last 20 years. METHODS A retrospective review of the meeting programs of vascular surgery societies was performed. Data were collected on abstract presenters, moderators, committee members and chairs, and officers (president, president-elect, vice president, secretary, and treasurer). The data were divided into early (1999-2009) and late (2010-2019) time periods. RESULTS Five regional and five national societies' data were analyzed, including 139 meetings. The mean percentage of female abstract presenters increased significantly from 10.9% in the early period to 20.6% in the late period (P < .001). Female senior authors increased slightly from 8.7% to 11.5%, but this change was not statistically significant (P = .22). Female meeting moderators increased significantly from 7.8% to 17.2% (P < .001), as well as female committee members increased from 10.9% to 20.3% (P = .003). Female committee chairs increased slightly from 10.9% to 16.9%, but this difference was not statistically significant (P = .13). Female society officers increased considerably from 6.4% to 14.8%. (P = .002). Significant variation was noted between societies, with five societies (three regional and two national) having less than 10% women at the officer level in 2019. There was a wide variation noted between societies in the percentage of female abstract presenters (range, 7.6%-34.9%), senior authors (3.9%-17.9%), and meeting moderators (5.4%-40.7%). CONCLUSIONS Over the past two decades, there has been a significant increase in the representation of women in vascular surgery societies among those presenting scientific work, serving as meeting moderators, and serving as committee members. However, the representation of women among committee chairs, senior authors, and society leadership has not kept up pace with the increase noted at other levels. Efforts to recruit women into the field of vascular surgery as well as to support the professional development of female vascular surgeons are facilitated by the presence of women in leadership roles. Increasing the representation of women in vascular society leadership positions may be a key strategy in promoting gender diversity in the vascular surgery field.

Abstract
Patients with chronic limb-threatening ischemia (CLTI) face numerous barriers to caring for lower extremity wounds. We explored the perceptions of CLTI patients to their wound/management and sought to determine attitudes towards their vascular provider as well as willingness for management through telemedicine. Patients admitted to hospital for treatment of Rutherford Grade 5 and 6 CLTI were asked complete a wound evaluation survey and took part in a semi-structured interview. Semi-structured interviews were recorded, transcribed, and analyzed using an inductive coding strategy. Codes were grouped for thematic analysis and aggregated into assertions. Eleven patients with a mean age of 60 years (35-79 years) were interviewed. All patients had peripheral artery disease (PAD) and eight patients had diabetes as well. Three overarching themes were identified. First, patients appear to have limited coping mechanisms and are overwhelmed by the care of their wounds. Second, in this cohort of patients, many had become passive observers of their care as demonstrated by a limited understanding of their disease processes and detachment from wound management. The third theme was how strong the desire to do everything to prevent limb loss was, but patients acknowledged this is hard to translate into real life with limited resources. Patients with CLTI have concerns that vascular providers must recognize and address to build strong patient-provider relationships and increase activation for management of their wounds and other medical conditions. Patients who have access to technology and with guidance may be able to understand getting care through remote medicine.

Abstract
Thoracic outlet syndrome (TOS) describes a complex disease process with three anatomic variations each with their own individual characteristics. Understanding the prevalence, diagnosis, and treatment of TOS is challenging for many providers. For this reason, the establishment of comprehensive care models and expert leadership by dedicated vascular surgeons with TOS experience has been invaluable.

Abstract
BACKGROUND Patient activation or level of engagement in one's medical care is linked to hospital readmissions and worse outcomes in a number of diseases. Patients with higher levels of activation are typically guiding their care rather than acting as passive observers of care. This study aims to determine if either patient demographics or type of vascular disease can predict patient activation. METHODS All patients presenting over a 4-month period to an outpatient vascular clinic were asked to complete the Patient Activation Measure (PAM) survey. In total, 257 completed surveys were collected. Survey responses were scored on a Likert scale with anchors. Responses are tallied with a score of 1-100 and converted to summary levels 1-4 in accordance with the previously validated scoring system. Level 1 patients are considered disengaged and overwhelmed. Patients in level 2 are becoming aware of their health care, but still struggle. Level 3 patients are taking action, while level 4 represents patients who are maintaining healthy behaviors and pushing further. Chi-squared test and multivariable regression were then performed to determine if patient characteristics or type of disease correlated with activation levels. RESULTS In total, 257 patients completed the survey. The mean participant age was 67 years (±15). Sixteen percent of patients lived alone, 58% were married, and in 39% mean household income was <$50,000. Overall, 21 patients (8.2%) were classified as level 1, 65 (25%) level 2, 94 (37%) level 3, and 77 (30%) level 4. The group comprised 32% peripheral artery disease (PAD), 20% carotid, 18% aortic/aneurysm, 14% venous, and 16% were various other vascular diseases. Over each disease group there was a wide range of activation, but no significant difference between the type of vascular disease and activation level. Chronic limb-threatening ischemia (CLTI) patients comprised 35% (n = 29) of the PAD group, and 66% of these patients reported an activation level of 3 (n = 10) or 4 (n = 9). There was no difference in the levels of activation reported by the CLTI patients compared to the general PAD cohort (P = 0.99). Multivariable analysis demonstrated that age, level of education, household income, and type of vascular disease correlated with PAM score, but there was no correlation between length of symptoms, race, or gender. CONCLUSIONS Patient activation is unpredictable using patient characteristics or type of vascular disease, and CLTI patients report high activation levels. Quality databases that collect only patient demographics may not fully capture patient predictors of poor outcomes. Use of the PAM survey should be further explored in vascular patients to correlate activation level with vascular-specific outcomes.

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

Abstract
The global SARS-CoV-2/COVID-19 pandemic has required a reduction in nonemergency treatment for a variety of disorders. This report summarizes conclusions of an international multidisciplinary consensus group assembled to address evaluation and treatment of patients with thoracic outlet syndrome (TOS), a group of conditions characterized by extrinsic compression of the neurovascular structures serving the upper extremity. The following recommendations were developed in relation to the three defined types of TOS (neurogenic, venous, and arterial) and three phases of pandemic response (preparatory, urgent with limited resources, and emergency with complete diversion of resources). • In-person evaluation and treatment for neurogenic TOS (interventional or surgical) are generally postponed during all pandemic phases, with telephone/telemedicine visits and at-home physical therapy exercises recommended when feasible. • Venous TOS presenting with acute upper extremity deep venous thrombosis (Paget-Schroetter syndrome) is managed primarily with anticoagulation, with percutaneous interventions for venous TOS (thrombolysis) considered in early phases (I and II) and surgical treatment delayed until pandemic conditions resolve. Catheter-based interventions may also be considered for selected patients with central subclavian vein obstruction and threatened hemodialysis access in all pandemic phases, with definitive surgical treatment postponed. • Evaluation and surgical treatment for arterial TOS should be reserved for limb-threatening situations, such as acute upper extremity ischemia or acute digital embolization, in all phases of pandemic response. In late pandemic phases, surgery should be restricted to thrombolysis or brachial artery thromboembolectomy, with more definitive treatment delayed until pandemic conditions resolve.

Abstract
OBJECTIVE Studies evaluating major amputation after initial minor amputation are few with rates of subsequent major amputation ranging from 14% to 35% with limited understanding of associated comorbidities and time to limb loss. The aim of this study is to determine the major amputation rates for patients who had already undergone an initial minor amputation and determine which factors are associated with the need for subsequent major amputation. METHODS Using statewide data between 2005 and 2013, patients with peripheral artery disease (PAD), diabetes mellitus (DM), and combined PAD/DM who had a lower extremity ulcer and who had also undergone a minor amputation were identified. These patients were evaluated for the rate of subsequent major amputation and competing risk Cox proportional hazards modeling was used to study which factors were associated with the risk of subsequent limb loss. RESULTS The cohort consisted of 11,597 patients (DM, n = 4254; PAD, n = 2142; PAD/DM, n = 5201) with lower extremity ulcers who underwent an initial minor amputation. The rate of any subsequent amputation was highest in patients with PAD/DM (23% vs DM = 17%, PAD = 17%; P = not statistically significant). The rate of subsequent minor amputation was 16% in the PAD/DM versus 15.2% in PAD and 12.2% in patients with DM (P < .001). Patients with PAD/DM had the highest rate of subsequent major amputation (6.3% vs DM = 5.2%, PAD = 2.1%; P < .001). There was no statistically significant difference in the median time to major amputation among the three groups (PAD/DM, 13 months; DM, 14 months; PAD, 8.6 months; P = NS). Patients who were revascularized before a repeat minor amputation had a decreased risk of a major amputation compared with those who were intervened on after a repeat minor amputation (hazard ratio, 0.002; 95% confidence interval, 0-0.22). Patients treated completely in the outpatient setting were also less likely to undergo subsequent major amputation (hazard ratio, 0.7; 95% confidence interval, 0.5-0.98) compared with those who required hospitalization or presented to the emergency room. CONCLUSIONS Patients with ulcers and combined PAD and DM have a higher risk for secondary major and minor amputation than patients with either disease alone with half of the limb loss occurring at approximately 1 year after the initial minor amputation. Additionally, early diagnosis and appropriate referral may result in decreased limb loss for these patients.

Abstract
BACKGROUND Critical limb ischemia remains a difficult disease to treat, with limited level one data. The BEST-CLI trial (Best Endovascular vs Best Open Surgical Therapy in Patients with Critical Limb Ischemia) is attempting to answer whether initial treatment with open surgical bypass or endovascular therapy improves outcomes, although it remains in enrollment. This study aims to compare amputation-free survival and reintervention rates in patients treated with initial open surgical bypass or endovascular intervention for ischemic ulcers of the lower extremities. METHODS AND RESULTS Using California nonfederal hospital data linked to statewide death data, all patients with lower extremity ulcers and a diagnosis of peripheral artery disease who underwent a revascularization procedure from 2005 to 2013 were identified. Propensity scores were formulated from baseline patient characteristics. Inverse probability weighting was used with Kaplan-Meier analysis to determine amputation-free survival and time to reintervention for open versus endovascular treatment. Mixed-effects Cox proportional hazards modeling was used to adjust for patient ability to manage their disease and hospital revascularization volume. A total of 16 800 patients were identified. Open surgical bypass was the initial treatment in 5970 (36%) while 10 830 (64%) underwent endovascular interventions. Patients in the endovascular group were slightly younger compared with the open group (70 versus 71 years, ±12 years; P<0.001). Endovascular-first patients were more likely to have comorbid renal failure (36% versus 24%), coronary artery disease (34% versus 32%), congestive heart failure (19% versus 15%), and diabetes mellitus (65% versus 58%; all P values <0.05). After inverse propensity weighting as well as adjustment for patient ability to manage their disease and hospital revascularization experience, open surgery first was associated with a worse amputation-free survival (hazard ratio, 1.16; 95% CI, 1.13-1.20) with no difference in mortality (hazard ratio, 0.94; 95% CI, 0.89-1.11). Endovascular first was associated with higher rates of reintervention (hazard ratio, 1.19; 95% CI, 1.14-1.23). CONCLUSIONS Patients with critical limb ischemia have multiple comorbidities, and initial surgical bypass is associated with poorer amputation-free survival compared with an endovascular-first approach, perhaps due to increased severity of wounds at the time of presentation.

Abstract
OBJECTIVE The surgical community commonly perceives a decline in surgical and patient care skills among residents who take dedicated time away from clinical activity to engage in research. We hypothesize that residents perceive a decline in their skills because of dedicated research time. SETTING UC Davis Medical Center, Sacramento, CA, an institutional tertiary care center. PARTICIPANTS General surgery residents and graduates from UC Davis general surgery residency training program, who had completed at least 1 year of research during their training. A total of 35 people were asked to complete the survey, and 19 people submitted a completed survey. DESIGN Participants were invited to complete an online survey. Factors associated with the decline in skills following their research years were examined. All statistical analyses were performed with IBM SPSS Statistics software. RESULTS A total of 19 current or former general surgery residents responded to the survey (54% response rate). Overall, 42% described their research as "basic science." Thirteen residents (68%) dedicated 1 year to research, while the remainder spent 2 or more years. Basic science researchers were significantly more likely to report a decrease in clinical judgment (75% vs. 22%, p = 0.013) as well as a decrease in patient care skills (63% vs. 0%, p = 0.002). Residents who dedicated at least 2 years to research were more likely to perceive a decline in overall aptitude and surgical skills (100% vs. 46%, p = 0.02), and a decline in patient care skills (67% vs. 8%, p = 0.007). CONCLUSIONS Most residents who dedicate time for research perceive a decline in their overall clinical aptitude and surgical skills. This can have a dramatic effect on the confidence of these residents in caring for patients and leading a care team once they re-enter clinical training. Residents who engaged in 2 or more years of research were significantly more likely to perceive these problems. Further research should determine how to keep residents who are interested in academics from losing ground clinically while they are pursuing research training.

Abstract
The creation of any patient database requires substantial planning. In the case of thoracic outlet syndrome, which is a rare disease, the Society for Vascular Surgery has defined reporting standards to serve as an outline for the creation of a patient registry. Prior to undertaking this task, it is critical that designers understand the basics of registry planning and a priori establish plans for data collection and analysis.

Abstract
Ankle-brachial indices (ABIs) are important for the assessment of disease burden among patients with peripheral artery disease. Although low values have been associated with adverse clinical outcomes, the association between non-compressible ABI (ncABI) and clinical outcome has not been evaluated among patients with critical limb ischemia (CLI). The present study sought to compare the clinical characteristics, angiographic findings and clinical outcomes of those with compressible (cABI) and ncABI among patients with CLI. Consecutive patients undergoing endovascular evaluation for CLI between 2006 and 2013 were included in a single center cohort. Major adverse cardiovascular events (MACE) were then compared between the two groups. Among 284 patients with CLI, 68 (24%) had ncABIs. These patients were more likely to have coronary artery disease ( p=0.003), diabetes ( p<0.001), end-stage renal disease ( p<0.001) and tissue loss ( p=0.01) when compared to patients with cABI. Rates of infrapopliteal disease were similar between the two groups ( p=0.10), though patients with ncABI had lower rates of iliac ( p=0.004) or femoropopliteal stenosis ( p=0.003). Infrapopliteal vessels had smaller diameters ( p=0.01) with longer lesions ( p=0.05) among patients with ncABIs. After 3 years of follow-up, ncABIs were associated with increased rates of mortality (HR 1.75, 95% CI: 1.12-2.78), MACE (HR 2.04, 95% CI: 1.35-3.03) and major amputation (HR 1.96, 95% CI: 1.11-3.45) when compared to patients with cABIs. In conclusion, ncABIs are associated with higher rates of mortality and adverse events among those undergoing endovascular therapy for CLI.

Abstract
BACKGROUND Treatment of severe aortoiliac occlusive disease (AIOD) frequently requires long-segment stenting of the common and external iliac arteries (CIA and EIA, respectively). This study aims to analyze the patency of the internal iliac artery (IIA) after placement of a CIA and EIA stents across the orifice. METHODS A retrospective analysis of all patients who underwent de novo ipsilateral stent placement in the CIA and EIA between 2006 and 2013 was performed. Kaplan-Meier analysis was used to analyze patency of the IIA, and Cox proportional hazard models were used to identify characteristics associated with occlusion. RESULTS We identified 77 patients and 93 limbs where ipsilateral CIA and EIA stents were placed. Preintervention angiographic review found 52 cases of a patent ipsilateral IIA where stents were placed across the origin of the IIA in 31 cases and staggered across the orifice in 20 limbs. Kaplan-Meier analysis demonstrated a 37% patency in limbs where the stent covered the IIA orifice compared to 78% patency in uncovered arteries (P = 0.04). New-onset buttock claudication developed in 4 patients, 2 with patent IIAs and 2 with occluded. New-onset impotence also developed in 3 patients with occluded IIA and 5 patients with patent IIAs. CONCLUSIONS Placement of stents across the origin of the IIA may not result in immediate occlusion, but long-term patency of covered IIAs is decreased compared to uncovered IIAs. This study is limited by a small sample size, but when treating AIOD, coverage of the internal iliac origin should be avoided to maintain patency of the pelvic circulation.

Abstract
OBJECTIVE This study reports all-payer amputation rates using state-based administrative claims data for high-risk patients with lower extremity (LE) ulcers and concomitant peripheral artery disease (PAD), diabetes mellitus (DM), or combination PAD/DM. In addition, we characterize patient factors that affect amputation-free survival. We also attempted to create a measure of a patient's ability to manage chronic diseases or to access appropriate outpatient care for ulcer management by accounting for hospital and emergency department (ED) visits in the preceding 60 days to determine how this also affects amputation-free survival. METHODS Patients admitted to nonfederal hospitals, seen in an ED, or treated in an eligible ambulatory surgery center within California from 2005 through 2013 with an International Classification of Diseases, Ninth Revision, Clinical Modification diagnosis code for a disease-specific LE ulcer were identified in the California Office of Statewide Health Planning and Development database. All subsequent hospital, ED, and ambulatory surgery center visits and procedures are captured to identify whether a patient underwent major amputation. Yearly amputation rates were determined to analyze trends. Amputation-free survival for the PAD, DM, and PAD/DM groups was determined. Cox modeling was used to evaluate the effect of patient characteristics. RESULTS There were 219,547 patients identified with an incident LE ulcer throughout the state. Of these, 131,731 were DM associated, 36,193 were PAD associated, and 51,623 were associated with both PAD and DM. From 2005 to 2013, the number of patients with LE ulcers who required inpatient admission, presented to the ED, or had outpatient procedures was stable. However, there was a statistically significant increase in overall disease-associated amputation rates from 5.1 in 2005 to 13.5 in 2013 (P < .001). Patients with PAD/DM had the greatest increase in amputation rates from 10 per 100 patients with LE ulcers in 2005 to 28 per 100 patients in 2013 (P < .001). Despite that patients with PAD/DM were 8 years younger than patients with PAD only, they had similar amputation-free survival. Within all age groups, men had worse amputation-free survival than women did. Race did not predict amputation-free survival, but having multiple prior ED or hospital admissions was a significant predictor of worse amputation-free survival. CONCLUSIONS Potentially preventable amputations associated with high-risk diseases are increasing among patients who require inpatient hospital admission, present to the ED, or require outpatient interventional treatment. This trend is most notable among patients with a combination of PAD and DM. Patients with repeated hospitalizations before admission for the LE ulcer had the highest risk of amputation.

Abstract
IMPORTANCE Deep vein thrombosis (DVT) isolated to the calf veins (distal to the popliteal vein) is frequently detected with duplex ultrasonography and may result in proximal thrombosis or pulmonary embolism (PE). OBJECTIVE To evaluate whether therapeutic anticoagulation is associated with a decreased risk for proximal DVT or PE after diagnosis of an isolated calf DVT. DESIGN, SETTING, AND PARTICIPANTS All adult patients with ultrasonographic detection of an isolated calf DVT from January 1, 2010, to December 31, 2013, at the Vascular Laboratory of the University of California, Davis, Medical Center were included. Patients already receiving therapeutic anticoagulation and those with a chronic calf DVT, a contraindication to anticoagulation, prior venous thromboembolism within 180 days, or diagnosis of a PE suspected at the time of calf DVT diagnosis were excluded. Data were analyzed from August 18, 2015, to February 14, 2016. EXPOSURES Intention to administer therapeutic anticoagulation. MAIN OUTCOMES AND MEASURES Proximal DVT or PE within 180 days of the diagnosis of the isolated calf DVT. RESULTS From 14 056 lower-extremity venous duplex studies, we identified 697 patients with an isolated calf DVT and excluded 313 of these. The remaining 384 patients were available for analysis (222 men [57.8%]; 162 women [42.2%]; mean [SD] age, 60 [16] years). The calf DVT involved an axial vein (anterior tibial, posterior tibial, or peroneal) in 243 patients (63.2%) and a muscular branch (soleus or gastrocnemius) in 215 (56.0%). Physicians attempted to administer therapeutic anticoagulation in 243 patients (63.3%), leaving 141 control participants. Proximal DVT occurred in 7 controls (5.0%) and 4 anticoagulation recipients (1.6%); PE, in 6 controls (4.3%) and 4 anticoagulation recipients (1.6%). Therapeutic anticoagulation was associated with a decreased risk for proximal DVT or PE at 180 days (odds ratio [OR], 0.34; 95% CI, 0.14-0.83) but an increased risk for bleeding (OR, 4.35; 95% CI, 1.27-14.9), findings that persisted after adjustment for confounding factors (ORs, 0.33 [95% CI, 0.12-0.87] and 4.87 [95% CI, 1.37-17.3], respectively) and sensitivity analyses. CONCLUSIONS AND RELEVANCE Rates of proximal DVT or PE are low after isolated calf DVT. Therapeutic anticoagulation is associated with a reduction of these outcomes but an increase in bleeding.

Abstract
BACKGROUND Endovascular aortic aneurysm repair (EVAR) is now established as first-line treatment for infrarenal aortic aneurysms in the United States. Recent data from randomized trials suggest that elective EVAR is cost-effective compared with open abdominal aortic aneurysm repair (oAAA). Cost analysis for urgent aneurysm repair has not been reported. We evaluated the cost of elective and urgent EVAR and compared it with oAAA at a tertiary academic medical center. METHODS All infrarenal AAA repairs performed from 2004 to 2010 were retrospectively reviewed (n = 172). Clinical characteristics of patients receiving EVAR and oAAA repair were compared. Direct costs, payments, and direct cost margin for the index inpatient episode were obtained from the hospital for all patients. Subsequent financial information including clinical, radiologic, and procedural cost was also available for 52 patients who had received all follow-up care in our institution for at least 1 year (EVAR 34, oAAA 18). RESULTS Overall, elective EVAR patients were older, but oAAA patients had more comorbidities, with significantly more patients having dyspnea at rest and being totally dependent for activities of daily living. EVAR patients had significantly shorter lengths of stay, regardless of urgency and urgent AAA repair occurred more often by oAAA than EVAR (P < 0.001; χ2). For elective patients, EVAR costs were 34.21% greater than for oAAA. There was a trend toward lower costs with EVAR versus oAAA in patients treated urgently by a ratio of 1.28:1. The hospital experienced a negative cost margin more often after elective EVAR versus oAAA. Negative cost margins were less frequent following urgent repair but still occurred twice as often in EVAR versus oAAA patients. Cost margins remained negative in all EVAR patients for at least 1 year and only 18% converted to a positive cost margin at a mean of 31 months. CONCLUSIONS At a tertiary academic institution, costs for elective EVAR are significantly higher than oAAA. EVAR may be relatively more cost-effective in urgent situations. Negative cost margins were more common in EVAR patients and 1-year follow-up with imaging in the same institution did not result in a positive margin.
