BACKGROUND: To evaluate the feasibility and efficacy of percutaneous endovascular treatment of peripheral aneurysms. METHODS: Forty-eight patients, M: 41, F: 7, mean age: 65.7 +/- 10.1 years (47-85 years), with 50 aneurysms were treated: 45 with covered stents (Cragg/Passager 22, Corvita 21, Wallgraft 1, Endotex 1) 4 with non-covered stents and 1 with stent graft. Twenty-six aneurysms located at the iliac artery, 12 at the femoral and 12 at the popliteal artery. Mean lesion length: 61.1 +/- 21.3 mm. Percutaneous approach used in all cases, femoral antegrade (n=24), retrograde (n=23), contralateral (n=2), popliteal (n=1). Stents used were 6-12 mm in diameter and 30-120 mm in length. Multiple stents used to cover all lesions in 20 cases. RESULTS: Immediate technical success was 96% (48/50). In 1 case of long, tortuous femoropopliteal aneurysm, it was impossible to cover the low part, due to rigidity of the device used, in 1 case of large iliac aneurysm there was incomplete immediate exclusion. No complication during the procedure. Four patients developed non-infectious fever/local pain. Eight thromboses occurred: 2 at iliac, 1 at femoral and 5 at the popliteal level. All other stents remained patent, the aneurysms completely excluded over a mean follow-up of 20.6 +/- 13.2 m, maximum 61 m. Primary patency: all lesions 82%, iliac 92%, femoropopliteal 78%. Secondary patency: all lesions 88%, iliac 96%, femoropopliteal 86%. CONCLUSION: Percutaneous endoluminal treatment of peripheral aneurysms seems safe and effective with high technical success and good long-term results, except for popliteal localization. It could be an alternative to surgery.
