Abstract

Purpose

To present a series of para-anastomotic iliac artery aneurysms treated with flow-diverting stents.

Case Reports

Three patients (2 men, 1 woman; ages 70, 73, and 78 years) with previous open aortoiliac reconstructions received a 12-mm-diameter Cardiatis Multilayer Stent to treat 4 para-anastomotic iliac artery aneurysms in an attempt to preserve their ipsilateral hypogastric arteries. After 1-year follow-up, all aneurysms were successfully excluded, with complete sac thrombosis in three and partial thrombosis in one. The diameter of the aneurysm was reduced in all by a median 6 mm. At 1 year, patency of the hypogastric artery was maintained in only the patient with partial sac thrombosis. No patient developed buttock claudication.

Conclusion

The use of flow-diverting stents for para-anastomotic iliac artery aneurysms resulted in reduction of iliac aneurysm diameter. However, intended patency of the ipsilateral hypogastric artery was not always observed. The feasibility of the technique has therefore not been shown for this specific indication.
