Single Center Outcomes of Percutaneous Deep Vein Arterialization in Patients with End-Stage Peripheral Artery Disease

Abstract

Background: Peripheral artery disease (PAD) can present as chronic limb threatening ischemia (CLTI) with ischemic pain and tissue loss. Progression of distal disease can lead to a “no option” or end-stage disease without traditional open or endovascular revascularization due to lack of pedal targets. Innovations in endovascular technology allow for the use of percutaneous deep vein arterialization (pDVA) to treat patients with CLTI. Purpose: We describe our experience and technique for treating four patients with end-stage PAD with pDVA. Research Design: Four patients with end-stage PAD were followed during and after pDVA creation. Technical success, complications, wound healing, and freedom from major amputation were analyzed. Data Collection and Analysis: Patient data and outcomes were collected via chart review and at time of follow up appointments in vascular surgery clinic. Results: Technical success was 100%, without post-procedural complications, and patients were continued on antiplatelet and anticoagulation. Three patients (75%) had successful wound healing, with 2 patients healing after transmetatarsal amputation (TMA), and 1 healing a distal foot ulceration that did not require surgery. One patient had worsening ischemic breakdown of a TMA, despite re-intervention on the pDVA, which required a below knee amputation (BKA). Freedom from major amputation was 75% overall, with an average follow-up time of 410 days post-procedure (Range: 113-563 days). Conclusions: Percutaneous deep vein arterialization attempts to provide blood flow to the preserved venous bed in patients with end-stage PAD. Exploration and utilization of this technique continues to expand in the modern vascular era. This case series highlights 4 patients with end-stage PVD who underwent pDVA, with 100% procedural success, and 75% limb salvage rate.
