Endovascular Revascularization of a Chronic Occluded Aortobifemoral Bypass

Abstract

Bilateral limb occlusion after aortobifemoral (ABF) prosthesis occurs in 1-3% patients. Multiple remedial choices are known in literature to manage a bilateral occluded ABF such as "redo" ABF bypass, axillobifemoral bypass, endovascular recanalization of the native aortoiliac system, and thrombectomy. We present a patient with an occluded ABF bypass since 2001. A new minimal invasive treatment strategy was performed by traversing the occluded limbs with aortic re-entry using stiff Terumo wires. To make way for safe passing of the stents, kissing balloon angioplasty was performed of the entire ABF bypass. Kissing Viabahn (W. L. Gore & Associates, Flagstaff, AZ) balloon-expandable stents were placed in the proximal part of the ABF bypass and extended with a Viabahn self-expandable stent (standard Viabahn). This option should be added to the known multiple remedial choices in case of bilateral limb occlusion of an ABF.
