Guided remote endarterectomy for superficial femoral artery occlusions: a technical note.

The aim of this paper was to describe a new modification of the remote endarterectomy for the treatment of long superficial femoral artery (SFA) occlusions and to present our preliminary results. Through a subinguinal incision and arteriotomy over the SFA origin, a hydrophilic guidewire was introduced into the subintimal plane of the SFA and advanced distally until reentry into the distal patent popliteal artery. The hydrophilic guidewire is exchanged for an Ablatz wire to provide support for the advancement of the single endarterectomy ring. The MollRing Cutter was introduced in the SFA after the removal of the single endarterectomy ring and it was advanced until the re-entry point. The atherosclerotic core was removed and a nitinol self-expanding stent was placed at the peripheral end of the endarterectomy. Arteriotomy was closed with a patch. Guided subintimally-assisted remote endarterectomy seems to be a successful and safe modification of the traditional technique in the treatment of SFA occlusion, in patients with critical limb ischemia.
