A systematic review and meta-analysis on the influence of sociodemographic factors on amputation in patients with peripheral arterial disease.

Objective: To identify disparities in sociodemographic factors that are associated with major lower limb amputation in patients with peripheral arterial disease (PAD).

Methods: A systematic review of the literature was performed to identify studies that reported major lower limb amputation rates in patients with PAD among different sociodemographic groups. Data that compared amputation rates on the basis of sex, race, ethnicity, income, insurance, geography, and hospital type were collected and described.

Outcomes of the Gore Excluder Iliac Branch Endoprosthesis Using Self Expanding or Balloon-Expandable Stent Grafts for the Internal Iliac Artery Component.

Objective: The GORE EXCLUDER Iliac Branch Endoprosthesis (IBE; W.L. Gore & Associates, Flagstaff, Arizona) was developed to be used in combination with a self-expanding stent graft (SESG) for the internal iliac artery (IIA) bridging stent.

Efficacy and safety of sonographer discretion to terminate a venous duplex ultrasound for diagnosis of deep vein thrombosis in coronavirus disease 2019 patients.

Objective: Sonographers performing venous duplex ultrasound (VDUS) of patients with coronavirus disease 2019 (COVID-19) have an increased risk of exposure owing to their close contact with these patients for an extended period. The objective of the present study was to evaluate the efficacy of a modified COVID-19 VDUS protocol to reduce sonographer exposure to COVID-19 patients.

Methods: We performed a single-center retrospective review.

Peripheral artery reconstructions using cryopreserved arterial allografts in infected fields.

Objective: Cryopreserved human arterial allografts are a recognized acceptable alternative for vascular reconstruction when other traditional conduits are either unavailable or contraindicated. We reviewed our experience using cryopreserved arterial allografts for peripheral artery reconstructions in contaminated and infected surgical fields.

Methods: A single-center, retrospective review was conducted of 57 patients who underwent a peripheral vascular reconstruction using a cryopreserved arterial allograft from January 2002 through July 2017.

Impact of Body Mass Index on Outcomes after Mesenteric Revascularization for Chronic Mesenteric Ischemia.

Background: Historically, patients with chronic mesenteric ischemia (CMI) are underweight with a low body mass index (BMI). However, with the recent obesity epidemic many of these patients now are overweight with a high BMI. We evaluated the impact of BMI on outcomes after mesenteric revascularization for CMI.

Implications of Intraoperative Vascular Surgery Assistance for Hospitals and Vascular Surgery Trainees.

Importance: Vascular surgeons possess a skill set that allows them to assist nonvascular surgeons in the operating room. Existing studies on this topic are limited in their scope to specific procedures or clinical settings.

Objective: To describe the broad spectrum of cases that require intraoperative vascular surgery assistance.

Two Cases of Aortic Intimal Intussusception During Endovascular Repair of an Acute Type B Dissection.

Purpose: To raise awareness of a previously undescribed complication of thoracic endovascular aortic repair (TEVAR) for aortic dissection that can lead to acute aortic occlusion and to highlight that early recognition, excision of the intimal flap, and open aortic repair can be lifesaving.

Case Report: Two patients underwent TEVAR for acute type B dissections complicated by abdominal malperfusion syndrome. During stent-graft deployment, the intimal flap circumferentially detached from its origin proximally with subsequent intussusception, leading to acute aortic occlusion.
