Abstract

PURPOSE:

During endovascular grafting of an abdominal aortic aneurysm (AAA), iliac limb extension to the external iliac artery may be indicated when the common iliac artery is ectatic or aneurysmal. Preliminary or concomitant coil embolization of the internal iliac artery (IIA) is thus necessary to prevent potential reflux and endoleak. We sought to determine the safety of hypogastric flow interruption in this setting.

METHODS:

We retrospectively reviewed 156 patients who underwent stent-graft AAA repair at two institutions between February 1, 1998, and January 31, 1999. Coil embolization of one or both IIAs was undertaken when the diameter of the common iliac artery was more than 20 mm to enable limb endograft extension to the external iliac artery. Bilateral procedures were staged.

RESULTS:

Thirty-nine (25%) of 156 patients were selected for coil embolization of one (n = 28) or both (n = 11) IIAs. The interventions were performed before (n = 31) or during (n = 8) the stent-graft procedure. Complications included groin hematomas in 3 patients, iliac artery dissection in 1, failure to catheterize the IIA in 2, and transient rise in the serum creatinine level in 3. One patient had erectile dysfunction, and five patients (13%) had buttock claudication after unilateral occlusion. Serious ischemic complications were not observed.

CONCLUSION:

Coil embolization of one or both IIAs appears to be safe in the setting of endovascular grafting of AAA. Buttock claudication is a relatively significant problem and may limit applicability of this strategy to patients who are unfit for standard open repair.
