Abstract
PURPOSE: To report a percutaneous technique for endovascular repair of iliac artery aneurysms using commercially available materials. METHODS: Ten patients (9 males; mean age 65 +/- 11 years) presented with 11 isolated iliac artery aneurysms; 3 patients were asymptomatic. Stent-grafts were customized for each patient from polytetrafluoroethylene grafts with Palmaz stents sutured at either end of the tube. The devices were delivered percutaneously through standard 14F sheaths and deployed by balloon dilation. RESULTS: All iliac aneurysms were excluded without procedural incident. One patient with chronic renal insufficiency (baseline serum creatinine 1.9 mg/dL) experienced transient contrast-induced renal failure inhospital. The average hospital stay was 2.5 days (range 1 to 7). One vessel thrombosed 2 weeks following the procedure; the culprit stenosis at the site of arterial cannulation was dilated. One patient died of myocardial infarction at 6 weeks. The remaining eight grafts are patent and free of endoleak at a mean 14-month follow-up. CONCLUSIONS: This percutaneous technique appears to be an acceptable alternative to open surgical repair.
