Importance of diversity, equity, and inclusion in the community practice setting.

Vascular surgeons of all backgrounds play an important role in providing high quality vascular surgical care in their communities. In America, with our diverse population and communities, patients presenting with vascular disease are very common and could pattern the community demographic. Often faced with the challenges of community hospital politics and demand, the vascular surgical workforce has continued to be active members in their communities, focusing on their strengths to lead vascular surgery healthcare in an environment of high patient demand. Having a varied vascular surgery workforce provides all patients afflicted by vascular disease a comfortable opportunity for compassionate and empathic vascular care. This is a significant strength of vascular care when diversity, equity, and inclusion are supported by the leadership.

Repair of an Anastomotic Pseudoaneurysm with a Novel Hybrid Technique.

INTRODUCTION: Anastomotic false aneurysms are a late complication of aortic grafting. Treatment usually consists of débridement of the degenerated tissue and placement of a short interposition graft. In infectious situations, graft excision is required. PATIENT HISTORY: An 80-year-old frail man with numerous comorbidities presented to clinic with an anastomotic pseudoaneurysm (PSA) between the left limb of an aortobifemoral Dacron graft and the common femoral artery (FA). TECHNICAL DETAILS: The superficial FA (SFA) and deep FA (PFA) were exposed and controlled from an anterior thigh approach. Sheaths were inserted in each artery. An Amplatzer II vascular plug (Abbott, Abbott Park, IL) was deployed in the PFA. A Viabahn (Gore, Flagstaff, AZ) was first deployed in the left limb of the Dacron graft and into the proximal SFA. A Viabahn VBX stent (Gore, Flagstaff, AZ) was then deployed from inside the Viabahn and going proximally further into the limb of the bifurcated Dacron graft. The proximal end of the Viabahn VBX was flared with a larger balloon. The arteriotomies in the SFA and PFA were then used to create a side-to-side anastomosis. There were no immediate complications. On 6 months follow-up, the PSA sac was noted to have decreased in size, and the stents to be patent with no endoleak. DISCUSSION: Elective surgical repair of anastomotic PSAs is preferred since emergent repair has significantly higher morbidity and mortality. Still, open elective repair has its own mortality and limb loss risks in addition to postoperative wound infection, seroma, hematoma, and recurrence, along with myocardial infarction and stroke. The novel procedure we performed eliminated the risk factors of redo groin incision and added easier-to-control vessels in a clean field. With this procedure being performed more often in the future, these changes will hopefully prove to reduce complications while preserving flow in both the SFA and PFA.

Predictors of wound complications following major amputation for critical limb ischemia.

OBJECTIVES: For patients with end-stage critical limb ischemia (CLI) who have already suffered over an extended period of time, a major amputation that is free of wound complications remains paramount. Utilizing data from the American College of Surgeons, National Surgical Quality Improvement Program (ACS-NSQIP), the objective of this report was to determine critical factors leading to wound complications following major amputation. METHODS: ACS-NSQIP was used to identify patients ≥ 50 years, with CLI, and having an ipsilateral below-(BKA) or above-knee amputation (AKA). The primary outcome was wound occurrence (WO) defined by affirmative findings of superficial infection, deep infection, and/or wound disruption. The secondary outcome was 30-day mortality. Following univariate analyses, a multiple logistic regression was performed to identify predictive factors. RESULTS: Between January 1, 2005 and December 31, 2008, 4250 patients fulfilled inclusion criteria (2309 BKAs and 1941 AKAs). WOs were 10.4% for BKAs and 7.2% for AKAs. For BKAs, increasing elevation in international normalized ratio (INR) predicted more WOs (P = .008, odds ratio [OR] 1.5 for every integral increase in INR) as did age 50 to 59 compared with older patients (P = .002, OR 1.9). For AKAs, being a current smoker predicted more WOs (P = .0008, OR 1.8) as did an increasing body mass index (BMI) (P = .02, OR 1.3 for every 10 kg/m(2) increase in BMI). Mortality was 7.6% for BKAs and 12% for AKAs. Complete functional dependence was most predictive of mortality following AKA (P < .0001, OR 2.5). Medical comorbidities such as history of myocardial infarcation (MI) (OR 1.8), congestive heart failure (CHF, OR 1.6), and chronic obstructive pulmonary disease (COPD, OR 1.6) predicted mortality following BKA, while dialysis use (OR 2.4), CHF (OR 2.3), and COPD (OR 2.1) predicted mortality following AKA. CONCLUSIONS: Wound occurrences and mortality rates after major amputation for CLI continue to be a prevalent problem. Normalization of the INR prior to BKA should decrease WOs. Heightened awareness in higher risk patients with improved preventive measures, earlier disease recognition, better treatments, and increased education remain critical to improving outcomes in an already stressed patient cohort.

Predictors of Groin Access Pseudoaneurysm Complication: A 10-Year Institutional Experience.

OBJECTIVE: In clinical practice, the incidence of femoral pseudoaneurysms requiring repair is small, but at a tertiary care center, the repair rate is higher due to referrals. We sought to specifically study patients who suffered postcatheterization pseudoaneurysms requiring thrombin injection or operative repair and compare them to our routine transfemoral endovascular patients to identify predictors of clinically significant pseudoaneurysms. The underlying goal would be to identify what makes these patients that develop pseudoaneurysms different. METHODS: A search of our billing records for Current Procedural Technology (CPT) codes of these 2 procedures between January 2008 and April 2018 was combined with our institution's Peripheral Vascular Intervention Vascular Quality Initiative database spanning from January 2013 to December 2017. A comparison was then performed between patients who had the outcome of operative intervention for a pseudoaneurysm complication and those who did not, with the goal of elucidating patient demographics and periprocedural factors that would predict pseudoaneurysm formation using univariate and multivariate analyses. RESULTS: There were 77 patients who required thrombin injection or open repair for access-related pseudoaneurysms and 324 patients who did not. Complications occurred more often in patients who were older than 75 (40.2% vs 21.9%; P = .0009), female (57.1% vs 38.6%; P = .003), obese (59.7% vs 33.3%; P < .001), hypertensive (96.1% vs 79.3%; P = .0005), who received a sheath >6F (32.4% vs 13%; P < .0001), intraoperative and postoperative anticoagulation (77.3% vs 32.7% and 52.1% vs 24.2%, respectively; P < .0001), and periprocedural P2Y12 inhibitors (48.7% vs 28%; P = .0005). Less complications were observed in patients who had a closure device used (42.9% vs 8.45%; P < .0001) and protamine reversal (26.5% vs 13.3%; P = .0163). CONCLUSIONS: Our findings validate published reports that incriminate a larger sheath size, perioperative anticoagulation, and female gender as increasing the rate of access site complications, with the use of a closure device being protective.

Computed tomography angiography to evaluate thoracic outlet neurovascular compression.

The objective was to evaluate the efficacy of computed tomography angiography with upper extremity hyperabduction to diagnose thoracic outlet syndrome. Over 5 years, 21 patients were treated surgically for neurogenic symptoms of thoracic outlet syndrome. For patients whose diagnosis was unclear after history and physical examination, adjunctive tests (duplex, magnetic resonance angiography, or computed tomography angiography) were performed to help establish the diagnosis. Five of the 6 computed tomography angiograms were positive. The sixth computed tomography was deemed to be an incomplete study. With mean follow-up of 9.4 months, 95% (n = 19) of patients with a positive hyperabduction test on physical examination were free of symptoms postoperatively. All patients with a positive computed tomography angiogram, with their neurovascular compression localized to the thoracic outlet, had successful operative decompression. Computed tomography angiogram with abduction of the arm can be used as an adjunct to confirm the diagnosis of neurovascular compression and then predict successful operative decompression.

The extent of lower extremity occlusive disease predicts short- and long-term patency following endovascular infrainguinal arterial intervention.

BACKGROUND: Endovascular revascularization of the femoral-politeal arterial segment has gained acceptance despite lower patency than surgical bypass due to lower morbidity. Choosing patients that are ideal candidates for endovascular therapy remains controversial. We have assessed hemodynamic factors that might predict longer primary patency after endovascular therapy. METHODS: Ninety-nine limbs were treated with endovascular therapy from January 2001 to January 2005 with a mean and median follow-up of 338 and 293 days. Primary patency was considered lost when recurrent symptoms developed, ankle-brachial index (ABI) decreased following initial improvement, or a subsequent procedure was required. Kaplan-Meier analysis was used to evaluate patency. RESULTS: Patients with an ABI > or =.5 prior to intervention had longer primary patency compared to those with an ABI less than .5 (P = .043). Having 1 or more patent tibial runoff vessels was associated with improved patency for the first 24 months post-procedure (P = .001). CONCLUSIONS: Patients with an ABI > or =.5 or at least 1 patent tibial vessel runoff have significantly higher hemodynamic and clinical success following endovascular therapy of the femoral-popliteal arterial segment.
