Abstract

Peripheral artery disease (PAD) can often present with chronic limb threatening ischemia (CLTI), including ischemic rest pain and severe tissue loss. Progression of PAD can lead to "no option" or end-stage disease in which there are no traditional open or endovascular interventions available for revascularization. This cohort of patients have a poor prognosis, with a major amputation rate of 40% and mortality of up to 20% at six months. For this patient population, surgical deep vein arterialization (DVA) is offered as an attempt to provide blood flow to the distal preserved venous bed and reverse the ischemic process. Surgical DVA has traditionally been offered as an option and was pioneered by Herb Dardik. The evolution of endovascular technology has allowed for percutaneous DVA (pDVA). Using ultrasound and fluoroscopic guidance, an arteriovenous channel is created between a tibial artery and vein and reinforced with covered stent grafts to increase distal limb perfusion with the goals of improving wound healing and amputation-free survival. Lysis of venous valves with a valvulotome also aids with reversal of flow into the distal venous system. Investigations of percutaneous deep vein arterialization are underway with one device, the LimFlow System (LimFlow SA, Paris, France), which is undergoing feasibility trials. Here we present the current clinical indications, feasibility, results, and our institutional experience with the use of percutaneous deep vein arterialization.
