Bilateral transpopliteal approach for treatment of complex SFA and iliac occlusions.

We present a successful case of percutaneous intentional extraluminal recanalization (PIER) of bilateral long superficial femoral artery (SFA) occlusions and a long iliac artery occlusion through ultrasound-guided retrograde popliteal artery punctures. To our knowledge, PIER of SFA occlusions via popliteal approach has been reported in only three cases, and subintimal recanalization of combined SFA and iliac occlusions has not been reported.
