There are no reports of perforation or bleeding of the SFA or the external iliac artery (EIA) during a popliteal approach, probably due to lack of flow in the occluded segment of the SFA. Some of the known complications encountered during this approach are arteriovenous fistula formation at the access site, occlusion of the popliteal artery if closure devices are used, and bleeding. A retrograde approach to chronic total occlusion (CTO) of the SFA through the ipsilateral popliteal artery has been used occasionally if an antegrade approach is not feasible or has failed. Different endovascular techniques are used successfully for revascularization of this artery. Peripheral arterial disease involvement of the superficial femoral artery (SFA) is common.
