Exploring Prognostic Implications of Race and Ethnicity in Patients With Peripheral Arterial Disease.

INTRODUCTION: Significant health inequalities in major adverse limb events exist. Ethnically minoritized groups are more prone to have a major adverse event following peripheral vascular interventions. This systematic review and meta-analysis aimed to describe the postoperative implications of racial and ethnic status on clinical outcomes following vascular interventions for claudication and chronic limb-threatening ischemia. METHODS: Searches were conducted across seven databases from inception to June 2021 and were updated in October 2022 to identify studies reporting claudication or chronic limb-threatening ischemia in patients who underwent open, endovascular, or hybrid procedures. Studies with documented racial and ethnic status and associated clinical outcomes were selected. Extracted data included demographic and clinical characteristics, vascular interventions, and measured outcomes associated with race or ethnicity. Meta-analyses were performed using random-effect models to report pooled odds ratios (ORs) with 95% confidence intervals (CIs). RESULTS: Seventeen studies evaluating the impact of Black versus White patients undergoing amputation as a primary intervention were combined in a meta-analysis, revealing that Black patients had a higher incidence of amputations as a primary intervention than White patients (OR: 1.91, 95% CI: 1.61-2.27). Another meta-analysis demonstrated that Black patients had significantly higher rates of amputation after revascularization (OR: 1.56, 95% CI: 1.28-1.89). Furthermore, multiple trends were demonstrated in the secondary outcomes evaluated. CONCLUSIONS: Our findings suggest that Black patients undergo primary major amputation at a significantly higher rate than White patients, with similar trends seen among Hispanic and First Nations patients. Black patients are also significantly more likely to be subjected to amputation following attempts at revascularization when compared to White patients.

Endovascular treatment of an iatrogenic right subclavian artery pseudoaneurysm associated with an arteriovenous fistula.

This report describes the case of a frail 36-year-old patient who underwent an endovascular treatment of a right subclavian artery pseudoaneurysm (SAP) associated with an arteriovenous fistula secondary to a traumatic central venous catheter insertion. The deployment of a covered stent from the innominate to the right common carotid artery combined with coiling of the SAP and the internal mammary artery was performed. Two additional covered stents were deployed from the vertebral artery to the distal subclavian artery to preserve right upper extremity circulation. This case highlights the feasibility of an endovascular treatment of a complex SAP in a candidate unsuitable for open surgery.

A mycotic aneurysm of a jejunal branch treated by aneurysmectomy without bowel resection.

Jejunal artery pseudoaneurysms are extremely rare, accounting for <1% of all visceral artery pseudoaneurysms. Fewer than 50 cases were reported in literature during the previous century. This case report describes the case of a 72-year-old man who underwent aneurysmectomy to treat a 21-mm mycotic jejunal artery pseudoaneurysm found in the setting of endocarditis. This pseudoaneurysm was treated with laparotomy, and gentle dissection of the tissues surrounding the pseudoaneurysm was performed before ligation and resection. This allowed for vascular collateral branch preservation, which, thus, avoided concomitant bowel resection. This report highlights the feasibility of this technique.
