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 an aortoiliac aneurysm or common iliac artery aneurysm and general health of the patient will determine how the aneurysm should be treated. In some cases, the physician may choose to block blood flow to (embolize) and cover the internal iliac artery to treat the aneurysm. While this is at times necessary, it often results in complications including buttock claudication and new onset sexual dysfunction.
SVS Clinical Practice Guidelines for patients with AAA2 include recom‐ mendations pertaining to internal iliac artery 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.
The GORE® EXCLUDER® Iliac Branch Endoprosthesis is the only FDA-approved branch endograft designed for endovascular repair of aortoiliac or common iliac aneurysms while preserving flow to the internal iliac artery. It is used in conjunction with the GORE® EXCLUDER® AAA Endoprosthesis or GORE® EXCLUDER ® Conformable AAA Endoprosthesis.
