Percutaneous endovascular treatment of peripheral aneurysms

Background. To evaluate the feasibility and efficacy of percutaneous endova scular 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/P assager 22, Corvita 21, Wallgraft 1, Endotex 1) 4 with non-covered stents a nd 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+/-2 1.3 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 a ll lesions in 20 cases. Results. Immediate technical success was 96% (48/50), In 1 case of long, to rtuous femoropopliteal aneurysm, it was impossible to cover the low part, d ue to rigidity of the device used, in 1 case of large iliac aneurysm there was incomplete immediate exclusion. No complication during the procedure. F our patients developed noninfectious fever/local pain. Eight thromboses occ urred: 2 at iliac, 1 at femoral and 5 at the popliteal level, All other ste nts remained patent, the aneurysms completely excluded over a mean follow-u p of 20.6+/-13.2 m, maximum 61 m, Primary patency: all lesions 82%, iliac 9 2%, femoropopliteal 78%, Secondary patency: all lesions 88%, iliac 96%, fem oropopliteal 86%, Conclusion, Percutaneous endoluminal treatment of peripheral aneurysms seem s safe and effective with high technical success and good long-term results , except for popliteal localization. It could be an alternative to surgery.
