Ipsilateral Iliac Branch Repair Using A Looped Wire, Precannulated Gate Technique

PurposeTo describe a novel, entirely ipsilateral femoral technique for distal endograft extension using the Gore Iliac Branch Endoprosthesis.TechniqueFemoral arterial access is obtained on the side of the intended repair, and a 16F sheath is inserted over a stiff wire. A looped wire is used to pre-cannulate the internal gate of the IBE device prior to insertion, and the device is then positioned and deployed. This through-wire guides access over the IBE flow divider and into the internal gate with a steerable sheath. The internal iliac artery is then selected, and a Viabahn VBX balloon-expandable stent (W.L. Gore, Flagstaff, AZ) is advanced into position and deployed. We present the successful completion of this technique in 4 patients.ConclusionThis novel technique allows distal endograft extension with an IBE device using only ipsilateral femoral access and is particularly useful for patients with aneurysmal iliac degeneration in the setting of prior open or endovascular aneurysm repair. This eliminates the need for upper extremity access or contralateral femoral access and navigation across the steep flow divider.
