Complex multilevel and multivessel endovascular revascularization through an occluded femoral-popliteal bypass in a patient with chronic limb threatening ischemia.

Abstract

Chronic limb-threatening ischemia (CLTI) represents the end stage of peripheral artery disease, a problem of growing prevalence and increased health care costs around the globe. CLTI is a highly morbid disease, incurring significant mortality, limb loss, pain, and diminished health-related quality of life. The major cause of non-traumatic lower extremity amputation are related to diabetes and CLTI. Between 2% to 3% of patients with peripheral artery disease present with a severe case of CLTI, a condition that is correlated with multilevel and multivessel arterial disease, calcification, and chronic total occlusions. Multiple technical strategies to successfully cross long occlusions in arterial segments have been described. Recanalization can be performed using endoluminal, subintimal, and retrograde techniques. We report a case of complex multilevel and multivessel endovascular revascularization through an occluded femoro-popliteal bypass in a patient with CLTI.
