Abstract
About 20% of patients with abdominal aortic aneurysms have associated iliac aneurysms. Distal sealing during the endovascular treatment of aortic-iliac aneurysms is a challenge that has led to the emergence of several technical options to achieve this goal over the years. Internal iliac artery embolization is associated with the risk of ischemic complications, such as gluteal necrosis, lower limb neurological deficit, colonic ischemia, impotence and gluteal claudication. This article summarizes the technical options for endovascular treatment of aortoiliac aneurysms with different approaches to preserving the patency of internal iliac arteries.
Highlights
The involvement of common iliac arteries occurs in 20% of patients with abdominal aortic aneurysms (AAA) and is a challenge to endovascular treatment because it compromises sealing and distal fixation of endoprostheses[1]
The purpose of this review is to discuss the endovascular techniques for preserving internal iliac artery patency in the treatment of aortoiliac aneurysms (AIA)
Occlusion coils are implanted in the IIA prior to the implantation of an endoprosthesis to cover its origin and to extend to the external iliac artery (EIA)[3,4]
