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.
