The Geographic Distribution of Vascular Surgeons and Trainees by State in 2023.

Background: Approximately 1.4 vascular surgeons/100,000 persons are estimated to fulfill current patient needs in the United States (US), but an ongoing shortage exists. The aims of this study are to provide an updated nationwide state-by-state workforce analysis and compare the distribution of practicing vascular surgeons and training opportunities.

Analysis of Oklahoma amputation trends and identification of risk factors to target areas for limb preservation interventions.

Objective: Annual trends of lower extremity amputation due to end-stage chronic disease are on the rise in the United States. These amputations are leading to massive expenses for patients and the medical system. In Oklahoma, we have a high-risk population because access to care is low, the number of uninsured is high, cardiovascular health is poor, and our overall health care performance is ranked 50th in the country.

Creating hemodialysis autogenous access in children and adolescents.

Objective: End-stage renal disease (ESRD) in childhood and adolescence is rare, with relatively few published reports of pediatric ESRD vascular access. This study analyzes a 10-year experience creating arteriovenous fistulas (AVFs) in children and adolescents. Our goal is to review our strategy for creating functional autogenous vascular access in younger patients and report our results.

Vascular surgeons are positioned to fight healthcare disparities.

Comprehensively managing vascular disease in the United States can seem overwhelming. Vascular surgery providers encounter daily stress-inducing challenges, including caring for sick patients who often, because of healthcare barriers, struggle with access to care, socioeconomic challenges, and a complex medical system. These individuals can present with advanced disease and comorbidities, and many have limited treatment options.

Vascular Surgery Training Positions and Applicant 10-Year Trends with Consideration for Further Expansion.

Background: There is a significant shortage of vascular surgeons in the United States and projections for these practicing surgical specialists continue to worsen. Annual appraisal of our workforce recruitment and growth is imperative.

Materials And Methods: Retrospective data were analyzed using the National Resident Matching Program from 2012-2022 applicant appointment years (specialty code for vascular surgery 450).

The association of racial and ethnic disparities and frailty in geriatric patients undergoing revascularization for peripheral artery disease.

Frailty is defined as a state of decreased physiologic reserve contributing to functional decline and adverse outcomes. Racial disparities in frail patients have been described sparsely in the literature. We aimed to assess whether race influences frailty status in geriatric patients undergoing revascularization for peripheral artery disease (PAD) with chronic limb-threatening ischemia (CLTI).

Community-engaged research in vascular surgery: An approach to decrease amputation disparities and effect population-level change.

Community-engaged research (CEnR) is a powerful tool to create sustainable and effective change in health outcomes. CEnR engages community members as equal partners, amplifying their voices and priorities by including them throughout the research process. Such engagement increases the relevance and meaning of research, improves the translation of research findings into sustainable health policy and practice, and ultimately enhances mutual trust among academic, clinical, and community partners for ongoing research partnership.

Venous thromboembolism as the first sign of malignancy.

Background: Venous thromboembolism (VTE) is commonly associated with hypercoagulability in patients with cancer; however, there have been few investigations of VTE as the first sign of malignancy and even fewer performed in the United States. The aim of our study was to evaluate the incidence and predictors of unrecognized malignancy in patients presenting with VTE.

Methods: We performed a 1-year retrospective analysis of the Nationwide Readmission Database, including patients aged 18 years or older, presenting with a primary diagnosis of deep vein thrombosis (DVT) or a pulmonary embolism (PE).

Recruitment & Retainment of Vascular Surgeons: Prophylactic Measures to Improve the Current Workforce Crisis.

Background: The vascular surgery workforce is in jeopardy with the current and increasing shortages. This study explores target populations for recruitment and aims to identify potential modifiable and nonmodifiable risk factors associated with reduced job satisfaction among practicing vascular surgeons to improve retention and prevent early retirement.

Methods: A cross-sectional national survey of surgeons (n = 1,043) was conducted from September 2016 to May 2017.

Autogenous Vascular Access in American Indians.

Background: American Indians (AI) or Alaska Natives, or in combination with another race, comprised 6.8 million individuals in 2010 and the population is expected to exceed 10 million in the current census. Diabetes is more common in AIs than in other races in the United States and is responsible for 69% of new onset end stage renal disease in AI patients.

Analysis of Early Lower Extremity Re-amputation.

Background: Data is scarce regarding the need for early re-amputation to a higher anatomic level. This study seeks to define outcomes and risk factors for re-amputation.

Methods: Patients undergoing primary major lower extremity amputation were identified within the 2012-2016 ACS-NSQIP database.

Creating reverse flow arteriovenous fistulas with a forearm cannulation target.

Background: Establishing a forearm arteriovenous fistula (AVF) offers preferred cannulation sites and preserves proximal access opportunities. When a radiocephalic AVF at the wrist is not feasible and the upper arm cephalic and median cubital veins are inadequate, an AV graft or more complex access procedure is often required. Creating a retrograde flow forearm AVF (RF-AVF) is a valuable alternative where the mid-forearm median antebrachial or cephalic vein is adequate, offering forearm cannulation zones with AVF outflow through deep and superficial collaterals.

Recruitment of General Surgery Residents into Vascular Surgery.

Background: Vascular surgery fellowship applications among general surgery residents have declined. Given this steady downward trend in vascular applicants in conjunction with a predicted critical shortage of vascular surgeons, a call to action for increased recruitment is needed. To improve recruitment efforts, a subgroup analysis of general surgery residents was performed to explore factors that influence interest in vascular surgery.

Frailty Syndrome in Patients With Lower Extremity Amputation: Simplifying How We Calculate Frailty.

Background: Frailty syndrome is an established predictor of adverse outcomes after surgical procedures. Our study aimed to compare the simplified National Surgical Quality Improvement Program 5-factor-modified frailty index (mFI-5) to its prior 11-factor-modified frailty index (mFI-11) with respect to the predictive ability for mortality, postoperative complications, and unplanned 30-d readmission in patients undergoing lower limb amputation.

Methods: The National Surgical Quality Improvement Program (2005-2012) databank was queried for all geriatric patients (>65 y) who underwent above-knee and below-knee amputations.

Racial and ethnic disparities in lower extremity amputation: Assessing the role of frailty in older adults.

Background: Frailty is a state of decreased physiologic reserve contributing to functional decline and is associated with adverse surgical outcomes, particularly in the elderly. Racial disparities have been reported previously both in frail individuals and in limb-salvage patients. Our goal was to assess whether race and ethnicity are disproportionately linked to frailty status in geriatric patients undergoing lower-limb amputation, leading to an increased risk of complications.

Present-day analysis of early failure after forefoot amputation.

Background: Forefoot transmetatarsal amputation is performed commonly to achieve limb salvage, but transmetatarsal amputations have a high rate of failure, requiring more proximal amputations. Few contemporary studies have examined the incidence of major amputation (transtibial or transfemoral) after transmetatarsal amputation. The goal of this study is to determine risk factors and outcomes for a more proximal amputation after forefoot amputation.

Avoiding hemodialysis access-induced distal ischemia.

Timely creation and maintenance of a safe and reliable vascular access is essential for hemodialysis patients with end-stage renal disease. Hemodialysis access-induced distal ischemia (HAIDI) is a recognized complication of arteriovenous fistulas and grafts that may result in serious or even devastating consequences. Avoiding such complications is clearly preferred over treatment of HAIDI once established.

Thirty-day outcomes after fenestrated endovascular repair are superior to open repair of abdominal aortic aneurysms involving visceral vessels.

Objective: Although few studies have reported outcomes after branched or fenestrated endovascular aortic aneurysm repair (FEVAR) of abdominal aortic aneurysms involving visceral vessels (AAA-Vs), no multi-institutional study has compared FEVAR with open surgery (OS) for AAA-Vs. Our objective was to compare 30-day outcomes after FEVAR vs OS for AAA-Vs.

Methods: Patients who underwent FEVAR (n = 535) and OS (n = 1207) for elective AAA-Vs were identified from the American College of Surgeons National Surgical Quality Improvement Program (NSQIP) 2008 to 2013 database.

Outcomes After Use of Aortouniiliac Endoprosthesis Versus Modular or Unibody Bifurcated Endoprostheses for Endovascular Repair of Ruptured Abdominal Aortic Aneurysms.

Objectives: Outcomes after endovascular repair (EVAR) of ruptured abdominal aortic aneurysms (rAAAs) have been widely published. There is, however, controversy on the role of the use of aortouniiliac endoprosthesis (AUI) versus modular or unibody bifurcated endoprosthesis (MUB) for repair of rAAAs. We study and compare 30-day outcomes after use of AUI and MUB for all rAAAs focusing specifically on patients with instability.

Superior Lower Extremity Vein Graft Bypass Patency among Married Patients with Peripheral Artery Disease.

Background: Outcome disparities associated with lower extremity bypass (LEB) for peripheral artery disease (PAD) have been identified but are poorly understood. Marital status may affect outcomes through factors related to health risk behaviors, adherence, and access to care but has not been characterized as a predictor of surgical outcomes and is often omitted from administrative data sets. We evaluated associations between marital status and vein graft patency following LEB using multivariable models adjusting for established risk factors.

Gender-specific Differences in Great Saphenous Vein Conduit. A Link to Lower Extremity Bypass Outcomes Disparities?

Background: Inferior lower extremity bypass (LEB) outcomes have been reported among women with peripheral arterial disease (PAD), but the mechanisms responsible for this disparity are unknown. Great saphenous vein (GSV) is considered the conduit of choice for LEB; GSV diameter is associated with graft patency and therefore is often used as a criterion for suitability for use as bypass conduit. We hypothesized that gender-based differences in GSV may contribute to LEB outcomes disparities.

Results of surgical management of acute thromboembolic lower extremity ischemia.

Objective: Acute lower extremity ischemia secondary to arterial thromboembolism is a common problem. Contemporary data regarding this problem are sparse. This report examines a 10-year single-center experience and describes the surgical management and outcomes observed.

Survival of a patient with trauma-induced mucormycosis using an aggressive surgical and medical approach.

Background: Mucormycosis is a deadly angioinvasive fungal infection that is increasing in incidence. Gastrointestinal and abdominal involvement is rare, has higher mortality rates, and is frequently diagnosed late.

Methods: We report a patient who sustained multiple gunshot wounds to the chest and abdomen and subsequently developed omental and hepatic mucormycosis.
