Bilateral Isolated Common and Internal Iliac Artery Aneurysms Treated with Iliac Branch Endoprostheses Using the Gluteal Arteries as Distal Landing Zones.

A 52-year-old male presented with bilateral isolated type III, 45-mm common and internal iliac artery (CIA and IIA) aneurysms (Fig. 1, 2) [1]. Both the CIAs exhibited an adequate proximal non-aneurysmatic segment, whereas the IIAs were aneurysmatic throughout their length (Fig. 3, 4). The patient underwent percutaneous endovascular treatment using iliac branch endoprosthesis (IBE) systems bilaterally (W. L. Gore and Associates, Inc.). The right superior and left inferior gluteal arteries were used as distal landing zones, as these presented lesser tortuosity than did the right inferior and left superior gluteal arteries, which were embolized before IBE deployment with 7-mm coils. Initially, self-expandable covered stents (Viabahn 9×100 mm; W. L. Gore & Associates, Inc.) were placed distally within the target vessels to better conform their anatomy. Subsequently, these stents were connected to the internal iliac leg of the IBE with balloon-expandable covered stents (VBX 11×79 mm; W. L. Gore & Associates, Inc.). The patient’s postoperative course was uneventful, with immediate mobilization Im ge of Vacular Srgery Bilateral Isolated Common and Internal Iliac Artery Aneurysms Treated with Iliac Branch Endoprostheses Using the Gluteal Arteries as Distal Landing Zones
