Retrograde Pedal/Tibial Artery Access for Treatment of Infragenicular Arterial Occlusive Disease

Endovascular intervention has emerged as an accepted modality for treating patients with critical limb ischemia. However, this therapy poses multiple challenges to the interventionalist due to the presence of widespread multilevel disease, long and complex occlusive lesions, and the common involvement of the tibial vessels. Retrograde pedal/tibial access is a relatively new technique that allows the treatment of tibial occlusive lesions when conventional endovascular techniques fail. This article reviews the technical details and published data regarding this technique and evaluates its use in this difficult-to-treat patient population.
