Abstract

Objectives : To evaluate the long-term results of recanalization with primary stenting for long and complex iliac artery occlusions.

Design : Retrospective non-randomized study.

Methods : Between 1996 and 2004, 38 patients underwent recanalization of an occluded iliac artery with subsequent stenting for TASC B lesions in 12 patients, TASC C in 10 and TASC D in 16. Thirty-one patients had Fontaine stage 2 B, four patients had stage 3 and one patient had stage 4. Two patients (5.4%) presented with acute ischemia and received trombolysis before recanalization. Patency results were calculated using Kaplan and Meier analysis. The mean follow-up was 26 months.

Results : Technical success was 97.4%. Thirty-day mortality was 2.7%. The primary patency rate was 94%, 89% and 77% at 1, 3 and 5 years respectively. Three re-occlusions (8.1%) and one restenosis (2.7%) were observed during follow-up. The secondary patency (SP) rate was 100%, 94% and 94% after 1, 2 and 3 years. Fifteen patients underwent an associated procedure. A kissing stent procedure in three patients, a contralateral PTA of an iliac stenosis in 8, a femorofemoral bypass in 2, a femoropopliteal bypass in 1 and an femoral endarterectomy in 2. The procedure related complication rate was 5.4%.

Conclusion : Long-term results of iliac recanalization are excellent without major complications if the procedure is technically successful. The endovascular procedure can be an alternative to an iliofemoral or aortobifemoral bypass in a high risk population.
