Late Type IIIb Endoleak after Low-Profile Endograft Implantation for Abdominal Aortic Aneurysm Treated by Hybrid Surgery

Abstract

Iliac artery rupture is a demanding complication that can occur during endovascular procedures, particularly when large-caliber introducers are required. We present the first case in the literature on the endobypass technique, a quick and effective reconstruction method for the iliofemoral axis. This clinical case highlights that thoracic endovascular aortic repair procedures require large-caliber introducers into the femoral and iliac arteries to allow passage of the delivery system. These arteries may be diseased, representing a high risk of rupture. In our case, placing a 20 Fr introducer, the iliac artery ruptured bilaterally. Therefore, we performed an endobypass deploying Viabahn stent-grafts into the common iliac artery and manually performed distal anastomosis on the femoral bifurcation.
