We present a case of Viabahn (W. L. Gore & Associates, Flagstaff, Ariz) collapse during popliteal artery aneurysm treatment. An elderly man with severe comorbidities presented with a 34-mm popliteal artery aneurysm. Proximal and distal landing sites of 11 and 9 mm, respectively, demonstrated by preoperative computed tomography angiography were confirmed by intraoperative angiography. After Viabahn deployment, angiography revealed a filling defect in the distal popliteal graft with poor flow. Balloon dilatation failed. A femoropopliteal bypass with aneurysm ligation was performed. Transection of the distal popliteal vessel demonstrated complete infolding. Our choice of grafts represented 15% to 18% proximal and distal oversizing. Focal areas of relative vessel narrowing may lead to incomplete graft unfolding and graft failure.
