Contemporary Management of Infrapopliteal Peripheral Arterial Disease

Abstract

Peripheral arterial disease (PAD) is a common manifestation of atherosclerotic vascular disease and the incidence of infrapopliteal PAD continues to rise in the population. The historical experience with surgical and endovascular interventions for infrapopliteal stenosis was disappointing as operators experienced high rates of early technical failures and procedural complications, coupled with high rates of restenosis in this vascular territory when compared with more proximal vascular beds. While patients with infrapopliteal PAD may be asymptomatic, the majority would ultimately develop intermittent claudication or may also present with critical limb ischemia. In this article, we review the current literature, and discuss some of the technical aspects of endovascular therapy in this vascular bed. We also emphasize the importance of adjunctive evidence-based therapies such as antiplatelet agents, statins, and lifestyle modification such as smoking cessation in this particularly high-risk cohort to optimize clinical outcomes.
