Endovascular retrieval of an entrapped balloon in a tibial artery.

Balloon entrapment is a rare complication of angioplasty in calcified or recalcitrant lesions. A 65-year-old man with chronic limb-threatening ischemia underwent balloon angioplasty of his heavily calcified tibial arteries with a low-profile, tapered, compliant balloon. The balloon became entrapped within the posterior tibial artery and required multiple endovascular maneuvers to deflate and separate the balloon from the calcified arterial wall. This case report describes several adjunctive techniques for retrieval of an entrapped balloon in small, calcified arteries before consideration of surgical removal. These techniques allow for minimally invasive retrieval and continuation of endovascular treatment thereafter.

Chronic Nonspinal Osteomyelitis in Adults: Consensus Recommendations on Percutaneous Bone Biopsies from the Society of Academic Bone Radiologists.

The diagnosis and management of chronic nonspinal osteomyelitis can be challenging, and guidelines regarding the appropriateness of performing percutaneous image-guided biopsies to acquire bone samples for microbiological analysis remain limited. An expert panel convened by the Society of Academic Bone Radiologists developed and endorsed consensus statements on the various indications for percutaneous image-guided biopsies to standardize care and eliminate inconsistencies across institutions. The issued statements pertain to several commonly encountered clinical presentations of chronic osteomyelitis and were supported by a literature review. For most patients, MRI can help guide management and effectively rule out osteomyelitis when performed soon after presentation. Additionally, in the appropriate clinical setting, open wounds such as sinus tracts and ulcers, as well as joint fluid aspirates, can be used for microbiological culture to determine the causative microorganism. If MRI findings are positive, surgery is not needed, and alternative sites for microbiological culture are not available, then percutaneous image-guided biopsies can be performed. The expert panel recommends that antibiotics be avoided or discontinued for an optimal period of 2 weeks prior to a biopsy whenever possible. Patients with extensive necrotic decubitus ulcers or other surgical emergencies should not undergo percutaneous image-guided biopsies but rather should be admitted for surgical debridement and intraoperative cultures. Multidisciplinary discussion and approach are crucial to ensure optimal diagnosis and care of patients diagnosed with chronic osteomyelitis.

Hybrid repair of an innominate artery pseudoaneurysm after blunt traumatic injury in a bovine arch.

Innominate artery injury is an uncommon consequence of blunt trauma to the neck due to its protected position behind the thorax. A 38-year-old male presented as a trauma with a right-sided pseudoaneurysm emanating from the distal innominate artery after falling from a three-story building. On imaging, he also had a bovine arch. He underwent hybrid repair with covered stent placement from the common carotid into the innominate artery, carotid-subclavian bypass, and plugging of the subclavian artery. The patient recovered with no cerebral insult, neurological deficits, or rupture. Post-traumatic innominate artery pseudoaneurysms can successfully be repaired via a hybrid surgical approach.

Contextualizing the BEST-CLI Trial Results in Clinical Practice.

Background: Chronic limb-threatening ischemia (CLTI) is associated with poor long-term outcomes. Although prompt revascularization is recommended, the optimal revascularization strategy remains uncertain. The BEST-CLI trial compared endovascular and open surgical revascularization for CLTI, but the generalizability of this study to the clinical population with CLTI has not been evaluated. Methods: We included Medicare beneficiaries aged 65-85 years with CLTI who underwent revascularization and would be eligible for enrollment in BEST-CLI between 2016 and 2019. The primary exposure was type of revascularization (endovascular vs autologous graft [cohort 1] vs nonautologous graft [cohort 2]), and the primary outcome was a composite of major adverse limb events (MALE) and death. MALE included above-ankle amputation and major intervention, which was defined as new bypass of index limb, thrombectomy, or thrombolysis. Results: A total of 66,153 patients were included in this study (10,125 autologous grafts; 7867 nonautologous grafts; 48,161 endovascular). Compared with those enrolled in BEST-CLI cohort 1, patients in this study were older (mean age, 73.5 ± 5.7 vs 69.9 ± 9.9 years), more likely to be female (38.3% [22,340/58,286] vs 28.5% [408/1434]), and presented with more comorbidities. Endovascular operators for the study population vs BEST-CLI cohort 1 were less likely to be surgeons (55.9% [26,924/48,148] vs 73.0% [520/708]) and more likely to be cardiologists (25.5% [5900/48,148] vs 14.5% [103/78]). When assessing long-term outcomes, the crude risk of death or MALE in this cohort was higher with surgery (56.6% autologous grafts vs 42.6% BEST-CLI cohort 1 at a median of follow-up 2.7 years; 51.6% nonautologous grafts vs 42.8% BEST-CLI cohort 2 at a median follow-up of 1.6 years) but similar with the endovascular cohort (58.7% Medicare vs 57.4% cohort 1 at 2.7 years; 47.0% Medicare vs 47.7% cohort 2 at 1.6 years). Of those who received endovascular treatment, the risk of incident major intervention was less than half in this cohort compared with the trial cohort (10.0% Medicare vs 23.5% cohort 1 at 2.7 years; 8.6% Medicare vs 25.6% cohort 2 at 1.6 years), although technical endovascular failures were not captured. Conclusions: These results suggest that the findings of the BEST-CLI trial may not be applicable to the entirety of the Medicare population of patients with CLTI undergoing revascularization.

How I do it: Pedal access and pedal loop revascularization for patients with chronic limb-threatening ischemia.

An increasing proportion of patients with chronic limb-threatening ischemia are older and have multiple comorbidities, including diabetes and renal failure. For those who are not candidates for a surgical bypass, this set of patients presents a challenge to vascular surgeons and interventionalists owing to the complex below-the-knee and increasingly below-the-ankle disease pattern that can fail traditional approaches for endovascular intervention. Two techniques, the retrograde pedal access and the pedal-plantar loop technique, can be useful in these settings and in skilled hands can be used safely, with a high technical success rate. In patients with chronic limb-threatening ischemia who are not candidates for a single-segment saphenous vein bypass, the retrograde pedal access technique can be used not only in the setting of failed antegrade treatment, but also primarily when faced with a difficult groin or as an adjunct during a planned antegrade-retrograde intervention. The pedal plantar loop technique allows for retrograde access to tibial vessels without retrograde vessel puncture and additionally offers the ability to treat the pedal-plantar arch, which may have added benefit in wound healing. We describe the tips and tricks for these two techniques used in our limb salvage practice.

Cyanoacrylate glue reactions: A systematic review, cases, and proposed mechanisms.

OBJECTIVE: Cyanoacrylate glue closure was first used in humans 10 years ago to treat venous reflux of the axial veins. Studies have since shown its clinical efficacy in vein closure. However, great need exists to elucidate further the types of specific adverse reactions that cyanoacrylate glue can cause for better patient selection and to minimize these events. In the present study, we systematically reviewed the literature to identify the types of reported reactions. In addition, we explored the pathophysiology contributing to these reactions and proposed the mechanistic pathway with inclusion of actual cases. METHODS: We searched the literature for reports of reactions following cyanoacrylate glue use in patients with venous diseases between 2012 and 2022. The search was performed using MeSH (medical subject headings) terms. The terms included cyanoacrylate, venous insufficiency, chronic venous disorder, varicose veins, vein varicosities, venous ulcer, venous wound, CEAP (clinical, etiologic, anatomic, pathophysiologic), vein, adverse events, phlebitis, hypersensitivity, foreign body granuloma, giant cell, endovenous glue-induced thrombosis, and allergy. The search was limited to the literature reported in English. These studies were evaluated for the type of product used and the reactions noted. A systematic review, in accordance with the PRISMA (preferred reporting items for systematic reviews and meta-analyses) method, was performed. Covidence software (Melbourne, VC, Australia) was used for full-text screening and data extraction. Two reviewers reviewed the data, and the content expert served as the tiebreaker. RESULTS: We identified 102, of which, 37 reported on cyanoacrylate use other than in the context of chronic venous diseases and were excluded. Fifty-five reports were determined appropriate for data extraction. The adverse reactions to cyanoacrylate glue were phlebitis, hypersensitivity, foreign body granuloma, and endovenous glue-induced thrombosis. CONCLUSIONS: Although cyanoacrylate glue closure for venous reflux is generally a safe and clinically effective treatment choice for patients with symptomatic chronic venous disease and axial reflux, some adverse events could be specific to the properties of the cyanoacrylate product. We propose mechanisms for how such reactions can occur based on histologic changes, published reports, and case examples; however, further exploration is necessary to confirm these theories.

Validity of the Global Vascular Guidelines in Predicting Outcomes Based on First-Time Revascularization Strategy.

BACKGROUND: The Global Vascular Guidelines (GVG) recommend selecting an endovascular versus open-surgical approach to revascularization for chronic limb-threatening ischemia (CLTI), based on the Global Limb Anatomic Staging System (GLASS) and wound, ischemia, and foot infection (WIfI) classification systems. We assessed the utility of GVG-recommended strategies in predicting clinical outcomes. METHODS: We conducted a single-center, retrospective review of first-time lower-extremity revascularizations within a comprehensive limb-preservation program from 2010 to 2018. Procedures were stratified by (1) treatment concordance with GVG-recommended strategy (concordant versus nonconcordant groups), (2) GLASS stages I-III, and (3) endovascular versus open strategies. The primary outcome was 5-year freedom from major adverse limb events (FF-MALE), defined as freedom from reintervention or major amputation, and secondary outcomes included 5-year overall survival, freedom from major amputation, freedom from reintervention, and immediate technical failure (ITF) during initial revascularization. Kaplan-Meier (KM) survival analysis and multivariate analysis with Cox proportional hazard models were performed on the primary and secondary outcomes. RESULTS: Of 281 first-time revascularizations for CLTI, 251 (89.3%) were endovascular and 186 (66.2%) were in the concordant group, with a mean clinical follow-up of 3.02 ± 2.40 years. Within the concordant group alone, 167 (89.8%) of revascularizations were endovascular. The concordant group had a higher rate of chronic kidney disease (60.8% vs. 45.3%, P = 0.02), WIfI foot infection grade (0.81 ± 1.1 vs. 0.56 ± 0.80, P = 0.03), and WIfI stage (3.1 ± 0.79 vs. 2.8 ± 1.2, P < 0.01) compared to the non-concordant group. After both KM and multivariate analyses, there were no significant differences in 5-year FF-MALE or overall survival between concordant and non-concordant groups. There was higher freedom from major amputation in the non-concordant group on KM analysis (83.9% vs. 74.2%, P = 0.025), though this difference was non-significant on multivariate analysis (hazard ratio [HR]: 0.49, 95% confidence interval [CI]: 0.21-1.15, P = 0.10). The open group had lower MALE compared to the endovascular group (HR: 0.39, 95% CI: 0.17-0.91, P = 0.029) attributed to a lower reintervention rate in the open group (HR: 0.31, 95% CI: 0.11-0.87, P = 0.026). GLASS stage was not associated with significant differences in outcomes, but the severity of GLASS stage was associated with ITF (2.1% in stage 1, 6.4% in stage 2, and 11.7% in stage 3, P = 0.01). CONCLUSIONS: In this study, CLTI treatment outcomes did not differ significantly based on whether treatment was received in concordance with GVG-recommended strategy. There was no difference in overall survival between the endovascular and open groups, though there was a higher reintervention rate in the endovascular group. The GVG guidelines are an important resource to help guide the management of CLTI patients. However, in this study, both concordance with GVG guidelines and GLASS staging were found to be indeterminate in differentiating outcomes between complex CLTI patients treated primarily with an endovascular-first approach. The revascularization approach for a CLTI patient is a nuanced decision that must take into account patient anatomy and clinical status, as well as physician skill and experience and institutional resources.

Utilizing remote access for electronic medical records reduces overall electronic medical record time for vascular surgery residents.

OBJECTIVE: Survey data suggests that surgical residents spend 20% to 30% of training time using the electronic medical record (EMR), raising concerns about burnout and insufficient operative experience. We characterize trainee EMR activity in the vascular surgery service of a quaternary care center to identify modifiable factors associated with high EMR use. METHODS: Resident activity while on the vascular surgery service was queried from the EMR. Weekends and holidays were excluded to focus on typical staffing periods. Variables including daily time spent, post-graduate year (PGY), remote access via mobile device or personal laptop, and patient census including operative caseload were extracted. Univariate analysis was performed with t tests and χ2 tests where appropriate. We then fit a linear mixed-effects model with normalized daily EMR time as the outcome variable, random slopes for resident and patient census, and fixed effects of PGY level, academic year, and fractional time spent using remote access. RESULTS: EMR activity for 53 residents from July 2015 to June 2019 was included. The mean daily EMR usage was 1.6 hours, ranging from 3.6 hours per day in PGY1 residents to 1.1 hours in PGY4 to 5 residents. Across all PGYs, the most time-consuming EMR activities were chart review (43.0%-46.6%) and notes review (22.4%-27.0%). In the linear mixed-effects model, increased patient census was associated with increased daily EMR usage (Coefficient = 0.61, P-value < .001). Resident seniority (Coefficient = -1.2, P-value < .001) and increased remote access (Coefficient = -0.44, P-value < .001) were associated with reduced daily EMR usage. Over the study period, total EMR usage decreased significantly from the 2015/2016 academic year to the 2018/2019 academic year (mean difference, 2.4 hours vs 1.78; P-value < .001). CONCLUSIONS: In an audit of EMR activity logs on a vascular surgery service, mean EMR time was 1.6 hours a day, which is lower than survey estimates. Resident seniority and remote access utilization were associated with reduced time spent on the EMR, independent of patient census. Although increasing EMR accessibility via mobile devices and personal computers have been hypothesized to contribute to poor work-life balance, our study suggests a possible time-saving effect by enabling expedient access for data review, which constitutes the majority of resident EMR activity. Further research in other institutions and specialties is needed for external validation and exploring implications for resident wellness initiatives.

Multidisciplinary Extremity Preservation Program Improves Quality of Life for Patients with Advanced Limb Threat.

BACKGROUND: The need for multidisciplinary care of patients with advanced limb threat is well established. We examined patient reported outcomes and health-related quality of life (HR-QoL) for those who completed a multidisciplinary extremity preservation program (EPP) at our institution. METHODS: Patients with advanced limb threat, who had previously failed standard management at a tertiary-care center, were referred to EPP for evaluation by a multidisciplinary panel of vascular, plastic, orthopedic and podiatric surgeons, along with infectious disease, prosthetics, orthotics, imaging, palliative care, social work and wound nursing specialists. HR-QoL was quantified before and after EPP participation with the RAND-36 questionnaire. The validated RAND-36 assesses physical function, role limitations caused by physical and emotional health problems, social functioning, emotional well-being, energy, pain and general health perceptions. RESULTS: From 2018 to 2020, 185 patients were referred to EPP. After review by the multidisciplinary panel, 120 were accepted into the program, 63 of whom completed their course of care; 9 were one-time consultations. The median number of EPP in-person care visits was 23 (13-54) per participant; 87.3% of patients received one or more surgical procedure, including operative debridement (73%), revascularization (44%), soft-tissue reconstruction or transplantation (46%), as well as hyperbaric oxygen therapy (11%) during their course of treatment. 85.7% of patients achieved complete wound healing, 41.5% occurring within 6 months. Ultimately, 14.3% required a major amputation. Graduates noted improvement in all categories of the HR-QoL upon completion, including those undergoing major amputation. On adjusted multivariate regression analysis, patients with immunocompromised status were more likely to show greater improvement in their social function (OR: 10.1; P < 0.044) and emotional role limitation (OR: 8.1; P = 0.042), while, patients with larger wound volume at presentation were more likely to have greater improvement in their general health (OR: 1.1; P < 0.049). Conversely, patients with a smoking history had less improvement in energy level (OR: 0.4; P = 0.044) and patients with dialysis-dependence had less improvement in social function (OR: 0.2; P = 0.034). CONCLUSIONS: Coordinated, multidisciplinary extremity preservation program improves HR-QoL of patients with complex limb threat, including those who are immunocompromised with impaired social function and emotional role limitations. Furthermore, study is warranted to better characterize the generalizability of this approach, including considerations of cost-effectiveness, wound recidivism, and limiting the number of in-person visits required to achieve complete healing.

How to build a limb salvage program.

Patients with chronic limb-threatening ischemia (CLTI) are medically complex and continue to experience high rates of amputation, despite improved diagnosis and treatment. Limb salvage programs and multidisciplinary teams provide comprehensive patient care and have been associated with reduced amputation rates. Recent societal guidelines suggest the adoption of limb salvage programs to improve care of patients with CLTI. In this article, we describe the critical components of a limb salvage program and outline the following steps to aid in their construction: community and institution assessment, formation of a multidisciplinary team, provision of patient care, and monitoring outcomes and processes refinement.

Utilization of lateral anterior lumbar interbody fusion for revision of failed prior TLIF: illustrative case.

BACKGROUND: The use of the lateral decubitus approach for L5-S1 anterior lumbar interbody fusion (LALIF) is a recent advancement capable of facilitating single-position surgery, revision operations, and anterior column reconstruction. To the authors' knowledge, this is the first description of the use of LALIF at L5-S1 for failed prior transforaminal lumbar interbody fusion (TLIF) and anterior column reconstruction. Using an illustrative case, the authors discuss their experience using LALIF at L5-S1 for the revision of pseudoarthrosis and TLIF failure. OBSERVATIONS: The patient had prior attempted L2 to S1 fusion with TLIF but suffered from hardware failure and pseudoarthrosis at the L5-S1 level. LALIF was used to facilitate same-position revision at L5-S1 in addition to further anterior column revision and reconstruction by lateral lumbar interbody fusion at the L1-2 level. Robotic posterior T10-S2 fusion was then added to provide stability to the construct and address the patient's scoliotic deformity. No complications were noted, and the patient was followed until 1 year after the operation with a favorable clinical and radiological result. LESSONS: Revision of a prior failed L5-S1 TLIF with an LALIF approach has technical challenges but may be advantageous for single position anterior column reconstruction under certain conditions.

Trends in annual open abdominal aortic surgical volumes for vascular trainees compared with annual national volumes in the endovascular era.

OBJECTIVE: A prior analysis predicted a shortfall in open abdominal aortic repair (OAR) experience for vascular trainees resulting from the rapid adoption, and increased anatomic suitability, of endovascular aortic aneurysm repair (EVAR) technology. We explored how EVAR has transformed contemporary open aortic surgical education for vascular trainees. METHODS: We examined the Accreditation Council for Graduate Medical Education case volumes of open abdominal aortic aneurysm (AAA) repair and reconstruction for aortoiliac occlusive disease via aortoiliac or femoral bypass (AFB) from integrated vascular surgery residents (VSRs) and fellows (VSFs) graduating from 2006 to 2017 and compared them to the national estimates of total OAR (open AAA repair plus AFB) in the Agency for Healthcare Research and Quality National Inpatient Sample using the International Classification of Diseases, 9th and 10th revision, procedural codes. Changes over time were assessed using the χ2 test, Student's t test, and linear regression. RESULTS: During the 12-year study period, the national annual total OAR and open AAA repair estimates had decreased: total OAR by 72.5% (estimate ± standard error: 2006, 24,255 ± 1185; vs 2017, 6690 ± 274; P < .001) and open AAA repair by 84.7% (estimate ± standard error: 2006, 18,619 ± 924; vs 2017, 2850 ± 168; P < .001). The AFB estimates had decreased by 33.0% (P < .001). The percentage of total OAR, open AAA repair, and AFB performed at teaching hospitals had significantly increased, from ∼55% to 80% (P < .001 for all). A 40.9% decrease was found for open AAA repairs performed by graduating VSFs (mean, 18.6 vs 11) but only a 6.9% decrease in total OAR cases (mean, 27.6 vs 25.7) owing to increasing AFB volumes (mean, 9.0 vs 14.7). The VSR graduates had consistently logged an average of ∼10 open AAA repairs, with a 31.0% increase in total OARs (mean, 23.2 vs 30.4), again secondary to increasing AFB volumes (mean, 11.4 vs 17.5). Although an absolute decrease was found in open aortic experience for VSFs, the rate of decline for the total OAR case volumes was not significantly different after VSR programs had been established (P = .40). CONCLUSIONS: As the incidence has decreased nationally, the use of OAR has been shifting toward teaching hospitals. Although open AAA procedures for trainees have been declining with the increased use of EVAR, open aortic reconstruction for aortoiliac occlusive disease has been increasing, playing an important role in ensuring that vascular trainees continue to have satisfactory OAR experience sufficient for meeting minimum graduation requirements. Strategies to maintain and maximize the education and experience from these cases should be the top priority for vascular surgery program directors.

Embolic Protection Devices are Not Associated with Improved Outcomes of Atherectomy for Lower Extremity Revascularization.

BACKGROUND: Atherectomy is associated with a risk of distal embolization, but the role of embolic protection devices (EPDs) during atherectomy is not well-defined. This study examines the utilization and impact of EPD on the outcomes of atherectomy during peripheral vascular interventions (PVIs). METHODS: The annual trend in utilization of EPD during atherectomy in the Vascular Quality Initiative PVI files (2010-2018) was derived. Patients with concomitant open surgery, acute limb ischemia, emergent-status, concomitant thrombolysis, missing indication, missing EPD use, and missing long-term follow-up data were excluded. The characteristics of patients undergoing atherectomy with and without EPD were compared. Propensity matching based on age, gender, race, chronic obstructive pulmonary disease, coronary artery disease, end-stage renal disease, prior PVI, indication, urgent-status, TransAtlantic interSociety Consensus classification, and anatomical location of lesion was performed. The perioperative and 1-year outcomes of the matched groups were compared. RESULTS: EPD was used in 23.3% of atherectomy procedures (n = 5,013/21,500). The utilization of EPD with atherectomy increased from 8.8% to 22.7% (P = 0.003) during the study period. Patients undergoing atherectomy without EPD were more likely to have ESRD (7.8% vs. 5.2%; P < 0.001), tissue loss (31% vs. 23.1; P < 0.001), tibial intervention (39.6% vs. 23.3%; P < 0.001), higher number of arteries treated (1.78 ± 0.92 vs. 1.68 ± 0.93; P = 0.001), and longer length of lesion (21.15 ± 21.14 vs. 19 ± 20.27 cm; P = 0.004). Conversely, patients undergoing atherectomy with EPD were more likely to be White (81.1% vs. 74%; P < 0.001), have a history of smoking (80.6% vs. 74.5%; P < 0.001), chronic obstructive pulmonary disease (24.8% vs. 21.6%; P < 0.037), coronary artery disease (38.5% vs. 33.2%; P = 0.002), prior percutaneous coronary intervention (24.3% vs. 19.9%, P = 0.005), prior coronary artery bypass grafting (32.3% vs. 24.9%; P < 0.001), and prior PVI (49.2% vs. 45.1%; P = 0.023). After propensity matching, there were 1,007 patients in each group with no significant difference in baseline characteristics. There was no significant difference in short-term outcomes including the rate of distal embolization, technical success, dissection, perforation, discharge to home, and 30-day mortality. The use of EPD was, however, associated with longer fluoroscopy time. At 1-year, there was also no difference in primary patency, ipsilateral minor or major amputation, ankle brachial index improvement, reintervention, or mortality rate between patients who underwent atherectomy with and without EPD. CONCLUSIONS: EPD has been increasingly used in conjunction with atherectomy especially in patients with claudication and femoropopliteal disease. However, the use of EPD during atherectomy does not seem to impact the outcomes. Further research is needed to justify the additional cost and fluoroscopy time associated with the use of EPD during atherectomy.

A gender-based analysis of predictors and sequelae of burnout among practicing American vascular surgeons.

OBJECTIVE: Surgeons report higher burnout and suicidal ideation (SI) rates than the general population. This study sought to identify the prevalence and gender-specific risk factors for burnout and SI among men and women vascular surgeons to guide future interventions. METHODS: In 2018, active Society for Vascular Surgery members were surveyed confidentially using the Maslach Burnout Index embedded in a questionnaire that captured demographic and practice-related characteristics. Results were stratified by gender. Univariate and multivariate logistic regression models were developed to identify predictors for the end points of burnout and SI. RESULTS: Overall survey response rate was 34.3% (N = 878) of practicing vascular surgeons. A higher percentage of women responded (19%) than compose membership in the Society for Vascular Surgery (13.7%). Women respondents were significantly younger, with fewer years in practice, and were less likely to be in private practice than the men who responded. Women were also less likely to be married/partnered, or to have children. The prevalence of burnout was similar for women and men (42.3% and 40.9%; P = nonsignificant); however, the prevalence of SI was significantly higher in women (12.9% vs 6.6%; P < .007). Whereas there was no difference in mean hours worked or call taken, women were more likely to have had a recent conflict between work and home responsibilities and to have resolved this conflict in favor of work. Although men and women had the same incidence of reported recent medical errors, women were less likely to self-report a recent malpractice suit or to think that a fair resolution was reached. There was no gender difference in reported work-related pain. Multivariable analysis revealed that not enough family time and work-related pain were predictors for burnout in both men and women. Additional factors were associated with burnout in men, such as malpractice and electronic medical record dissatisfaction. Multivariable analysis revealed that work-related pain was an independent predictor for SI for the entire cohort. CONCLUSIONS: The prevalence of burnout among vascular surgeons is high. Women vascular surgeons have double the rates of SI compared with male vascular surgeons. Taken together, this study demonstrated that many of the same factors are associated with burnout in women and men, which include not enough family time, conflict between work and personal life, and work-related pain. Additional factors in men included conflict between work and family, work-related pain, and electronic medical record dissatisfaction.

Interview experience, post-interview communication, and gender-based differences in the integrated vascular surgery residency match.

OBJECTIVE: Integrated vascular surgery residency (IVSR) applicant perspective about the match process has been rarely studied, yet this has important implications on trainee recruitment. We sought to better understand the nature of the interview process and post-interview communication and its impact on students' ranking choices. METHODS: A voluntary and anonymous survey was sent to students who matched to IVSR in 2020, inquiring about interviews, post-interview communications, and factors influencing students' rank lists. RESULTS: Seventy of the 73 matched students completed the survey (96% response rate; 23 female and 47 male respondents). Applicants reported they were asked questions about other programs of interest (81.4%), top choice programs (65.7%), marital status (32.9%), family planning (7.1%), and religion (1.4%) during interviews. Female applicants were more frequently asked questions about family planning (17.4% vs 2.1%; P < .01) and marital status (52.5% vs 23.4%; P < .01) compared with male applicants. After interviews, 92.9% of applicants notified their top choice program of their ranking preference. Of applicants, 61.4% received post-interview communication with regards to ranking from at least one program, initiated by program directors in 81.3% of instances. Among these applicants, 58.1% reported that the post-interview communication had an impact on their rank list, and 46.5% matched at a program by which they were contacted. Of applicants, 5.7% were asked by a program to reveal their ranking of the program, and 11.4% were promised by a program to be ranked first if the applicant reciprocally ranked them first. Female and male applicants weighed program culture, operative volume, mentorship, and prestige equally in making their rank list. Male applicants weighed the sub-internship experience more significantly; however, female applicants weighed the sub-internship experience, personal relationships in certain cities, dedicated professional development years, and large female representation in the program more heavily (P < .02). CONCLUSIONS: This study provides insight into the interview experience and impactful factors for the vascular surgery match. Both female and male applicants were asked a high number of questions about personal matters unrelated to medical school performance. Female applicants, however, experienced a higher proportion of these instances, particularly regarding family planning. These findings demonstrate the factors that are important to applicants in the match process and raises awareness of potential challenges in the interview and recruitment process.

Society for Vascular Surgery best practice recommendations for use of social media.

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.

Contemporary outcomes of traumatic popliteal artery injury repair from the popliteal scoring assessment for vascular extremity injury in trauma study.

OBJECTIVE: Traumatic popliteal artery injuries are associated with the greatest risk of limb loss of all peripheral vascular injuries, with amputation rates of 10% to 15%. The purpose of the present study was to examine the outcomes of patients who had undergone operative repair for traumatic popliteal arterial injuries and identify the factors independently associated with limb loss. METHODS: A multi-institutional retrospective review of all patients with traumatic popliteal artery injuries from 2007 to 2018 was performed. All the patients who had undergone operative repair of popliteal arterial injuries were included in the present analysis. The patients who had required a major lower extremity amputation (transtibial or transfemoral) were compared with those with successful limb salvage at the last follow-up. The significant predictors (P < .05) for amputation on univariate analysis were included in a multivariable analysis. RESULTS: A total of 302 patients from 11 institutions were included in the present analysis. The median age was 32 years (interquartile range, 21-40 years), and 79% were men. The median follow-up was 72 days (interquartile range, 20-366 days). The overall major amputation rate was 13%. Primary repair had been performed in 17% of patients, patch repair in 2%, and interposition or bypass in 81%. One patient had undergone endovascular repair with stenting. The overall 1-year primary patency was 89%. Of the patients who had lost primary patency, 46% ultimately required major amputation. Early loss (within 30 days postoperatively) of primary patency was five times more frequent for the patients who had subsequently required amputation. On multivariate regression, the significant perioperative factors independently associated with major amputation included the initial POPSAVEIT (popliteal scoring assessment for vascular extremity injury in trauma) score, loss of primary patency, absence of detectable immediate postoperative pedal Doppler signals, and lack of postoperative antiplatelet therapy. Concomitant popliteal vein injury, popliteal injury location (P1, P2, P3), injury severity score, and tibial vs popliteal distal bypass target were not independently associated with amputation. CONCLUSIONS: Traumatic popliteal artery injuries are associated with a significant rate of major amputation. The preoperative POPSAVEIT score remained independently associated with amputation after including the perioperative factors. The lack of postoperative pedal Doppler signals and loss of primary patency were highly associated with major amputation. The use of postoperative antiplatelet therapy was inversely associated with amputation, perhaps indicating a protective effect.

Factors influencing medical student choices in the integrated vascular surgery match: Implications for future post-pandemic residency matches.

OBJECTIVE: Integrated vascular surgery residency is among the most competitive specialties, but little is known about the applicant perspective. The coronavirus disease 2019 outbreak impacted the 2021 integrated vascular surgery residency match because of travel restrictions. We sought to better understand pre-pandemic applicant recruitment strategies, logistics of away rotations, and the residency interview process to identify areas for improvement in the application process. METHODS: An anonymous survey was sent to matched students in 2020, inquiring about motivations for pursuing vascular surgery (VS), logistic of away rotations and interviews, and factors influencing students' rank lists. RESULTS: Seventy of the 73 matched students completed the survey (95.9% response rate). The median age was 27 (range, 25-41); 32.9% were female, 91.4% were U.S. medical students, and 77.1% were from institutions with a VS training program. Factors most strongly influencing the decision to choose VS as a career were interest in open vascular procedures, endovascular procedures, perceived job satisfaction, emerging technologies, and influence of a mentor. The prospect of the job market, future salary, and competitiveness of the application process had the least impact. Of the matched students, 82.9% completed an away rotation (median, 2; range, 1-4), with 51.7% of students paying a total cost of more than $2500. Fifty percent of students matched either at their home institution or where they had performed an away rotation. Students reported application submissions to a median of 50 programs (range, 1-70) and interviewed at 17 (range, 1-28), with 40% of students paying a total of more than $4000 for interview costs. The most significant factors affecting students' rank lists included program culture, open aortic surgical volume, geography, and complex endovascular procedure volume. Tours of facilities, resident salary, and male/female distribution had the least importance. CONCLUSIONS: Successfully matched applicants in 2020 prioritized operative case volume and program collegiality when ranking programs. Despite their high cost, away rotations played an important role in the Match, suggesting that time spent at potential institutions allowed ideal assessment of factors for students. The high average number of away rotations and in-person interviews performed in 2019-2020 was limited for the 2021 Match due to coronavirus disease 2019 restrictions. Programs will have to continue developing creative alternatives or additions to away rotations and the application processes to assure continued success in future post-pandemic Match cycles.
