AIM: The aim of this retrospective, single institution study was to describe our 4-year experience with the endovascular repair of isolated iliac artery aneurysms.
METHODS: Between May 1997 and June 2001, 16 patients (15 males; mean age 64+/-9 years), were treated with covered stent grafts. Twelve of the endovascular procedures were performed under epidural and 4 under local anaesthesia. The percutaneous approach was employed in 13 cases and the femoral artery had to be exposed in 3 cases that demanded simultaneous revascularization of the peripheral circulation (n=2) or required a 16 F sheath to employ a Baxter Lifepath stent graft (n=1). The mean size of the iliac aneurysms was 4.5 cm (range 3.5 to 5.2 cm). Four aneurysms involved the hypogastric ostium in absence of any distal neck.
RESULTS: All the patients underwent initially successful endovascular treatment of isolated iliac aneurysms and were followed from 3 to 52 months (mean 18 months). No procedural deaths and no acute or late graft thrombosis occurred. The perioperative complications included 1 dissection of the external iliac artery that required a further endovacular procedure and 1 case of endovascular leak fed to the hypogastric artery. A CT scan 4 months later showed spontaneous thrombosis of aneurysm and no further leakage. Two patients had undergone combinated femoro-popliteal arterial bypass.
CONCLUSION: In our early clinical experience the use of self-expandable covered stent graft successful treated isolated iliac artery aneurysms. Endovascular repair is a safe and effective technique with good midterm results in patients at standard and high risk.
