Staged endovascular repair of bilateral internal iliac artery aneurysms

Internal iliac artery (IIA) aneurysms present several challenges to the vascular surgeon: They are uncommon, and the often difficult repair is associated with relatively high morbidity/mortality. Bilateral internal iliac disease adds technical complications secondary to ischemic complications. In this case, a 76-year-old male with bilateral IIA aneurysms underwent staged endovascular coil embolization, resulting in exclusion of flow to the aneurysms and avoidance of ischemic postoperative complications. Angiography during the procedure verified complete bilateral IIA occlusion, which remained intact at 6-week and 1 year follow-up (computed tomography). This case illustrates successful repair of bilateral IIA using endovascular techniques.
