ResumoIliac aneurysms can occur concomitantly in 15 to 20% of abdominal aortic aneurysms. The common iliac arteries serve as the distal landing zones for the iliac limbs of abdominal aortic stent grafts, and for most currently available devices, the maximum treatable iliac size is 20 mm. When the iliac artery diameter exceeds this, alternative landing zones or adjunctive techniques are required to achieve an adequate distal seal and fixation, which typically involves occlusion of the hypogastric artery origin and extension to the external iliac artery. The clinical sequelae of acute hypogastric occlusion mostly involve symptoms of hip and buttock ischemia (claudication), which can occur in up to 40% of cases. In this article, a novel method of endovascular management of common iliac artery aneurysms in the setting of endovascular aortic aneurysm repair is described using an investigational (United States only) iliac branch device that preserves antegrade perfusion to the hypogastric artery to decrease the potential risks of pelvic ischemia.
