To evaluate the immediate and long-term results of primary stent placement for complex iliac artery occlusive disease compared with simple disease.

Between 1989 and October 2004, 329 patients with iliac artery occlusive disease were treated with primary stent placement. Lesion severities were classified according to TransAtlantic Inter-Society Consensus (TASC). They consisted of 98 TASC A lesions, 117 TASC B lesions, 57 TASC C lesions, and 57 TASC D lesions in this retrospective study. Technical success rates, procedure time, and cumulative primary patency rates were compared between the complex lesion group (TASC C and D) and the simple lesion group (TASC A and B).

Technical success rates of the complex lesion group and the simple lesion group were 100% and 99%, respectively. There was no significant difference between the complex lesion and simple lesion group. The procedure time was significantly longer in complex lesion group (149±62 minutes) when compared with that in the simple lesion group (99±27 minutes) (p<0.001; Unpaired t-test). The cumulative primary patency rates at 1, 3, 7 years in complex lesion group were 92%, 90%, and 90%, respectively. The cumulative primary patency rates at 1, 3, 7 years in the simple lesion group were 99%, 94%, and 93%, respectively. There was no significant difference between the complex and simple lesion group (p=0.18; Kaplan-Meier method, Logrank test).

Primary stent placement as treatment of complex iliac artery occlusive disease provides durable long-term effectiveness, although it takes longer time compared with that of simple lesions.
