In approximately 25 percent of patients with an abdominal aortic aneurysm (AAA), the aneurysm extends into at least one of the common iliac arteries.1 These are referred to as aortoiliac aneurysms. Additionally, the aneurysm may be isolated to the common iliac artery, which are referred to as common iliac artery aneurysms.
The size and location of the aortoiliac aneurysm, or common iliac artery aneurysm, and general health, will determine how the aneurysm should be treated. Methods such as "coil and cover" or embolization of the internal iliac artery often result in complications, including buttock claudication and new onset sexual dysfunction.
SVS Clinical Practice Guidelines for Abdominal Aortic Aneurysm2 (AAA) include recommendations pertaining to hypogastric preservation during EVAR treatment. These recommendations include using a Food and Drug Administration (FDA) approved branch endograft in anatomically suitable patients to maintain perfusion to at least one internal iliac artery.
GORE® EXCLUDER® Iliac Branch Endoprosthesis is the only FDA-approved device designed for the treatment of common iliac artery aneurysms or aortoiliac aneurysms. It is used in conjunction with the GORE® EXCLUDER® AAA Endoprosthesis and allows for endovascular repair.
