OBJECTIVE: Hybrid lower extremity revascularization has been well described, typically consisting of common femoral endarterectomy (CFE) followed by direct patch puncture and endovascular treatment of any distal disease. We describe a modified technique that obviates the need for endovascular re-entry and simplifies treatment at the proximal and distal endpoints.
METHODS: The REWIRE technique begins with retrograde arterial access via a patent tibial, pedal or femoropopliteal vessel. The diseased segment is crossed in the subintimal plane. Once the wire reaches the common femoral artery (CFA), the vessel is surgically exposed. Arteriotomy is performed and the wire is externalized during standard CFE. With through-wire access achieved, a sheath is inserted and the distal disease is treated. The proximal extent of the endovascular revascularization is incorporated into a standard CFE with patch angioplasty.
RESULTS: Seven patients with chronic limb-threatening ischemia were treated with this approach, all with long segment occlusions of the SFA and significant CFA disease. The SFA disease was stented and bovine pericardial patch was used for CFE in all. Technical success was achieved in all patients. There were no complications related to the retrograde puncture site, which was controlled with manual pressure (4) or excluded with a covered stent (3). Thirty-Day freedom from major adverse limb events was 100%.
CONCLUSIONS: The REWIRE technique is an effective approach to hybrid revascularization involving the CFA. By crossing the occluded segment in a retrograde fashion and surgically externalizing the wire during CFE, the proximal and distal endpoints can be addressed with ease, the profunda femoris is protected under direct visualization, and the need for endovascular re-entry is eliminated.
