PURPOSE: As many as 39% of patients who undergo aortic endografting for abdominal aortic aneurysm disease will have ectasia of the iliac arteries that will require intervention. Coil embolization of the internal iliac artery and extension of the graft to the external iliac artery is one solution to this problem. However, 19%-41% of these patients experience buttock claudication, which may be permanent, after unilateral embolization. The authors examined an alternative: The use of larger-sized aortic cuffs to seal the iliac limb. Outcomes and short-term results are presented in this article. MATERIALS AND METHODS: From October 1999 to August 2000, 144 AneuRx stent-grafts were placed at the authors' institution. Among the population receiving stent-grafts, 14 patients had 15 aortic cuffs placed across the distal iliac graft limbs to seal them and preserve flow to the internal iliac artery. One patient had bilateral cuffs placed. Five patients had embolization of the contralateral internal iliac artery because of bilateral disease. Patients were followed with computed tomography (CT) at 1, 6, and 12 months to evaluate for endoleaks. RESULTS: One- and 6-month endoleak rates, determined from only those patients with follow-up CT, were 0% and 10%, respectively. One type II endoleak was first discovered 9 months after graft placement. It sealed spontaneously at 15-month follow-up. One patient among the five who had internal iliac artery embolization had claudication. Mean CT follow-up was 7.8 months (range, 1-15). One patient declined CT but was alive and well 11 months after endografting. One patient moved across the country and declined follow-up. CONCLUSION: Placement of aortic cuffs in dilated iliac arteries can preserve flow to the ipsilateral internal iliac artery and provide an adequate seal. Additionally, the option of later treatment is maintained. Patients with bilateral iliac ectasia can undergo stent-graft placement without bilateral internal iliac artery embolization. Longer-term follow-up in larger numbers of patients will be important to determine the ultimate durability of this technique.
