Abstract:Objective:To study the therapy effect and review of the technique of endovascular treatment for iliac artery occlusion.
Methods :Thirty-four patients with occlusion of iliac artery were treated with endovascular therapy. The technical success rate, complication rate, the mid-term to long-term results were analyzed.
Results:The technical success rate was 100%. Iliac artery rupture in one case(2.94%) and no other major intraoperative complication occurred. Ankle-brachial index increased from (0.40±0.14) to (0.81±0.13) (t=2.67, P=0.02). All patients were followed up with mean time (19.32±2.22) months(range from 3 to 42 months). Iliac artery re-stenosis occurred in seven cases and re-occlusion in 3 cases. The primary, primary-assisted and secondary patency rate was 86.27%, 74.40%, 61.81%, 52.98%; 96.43%, 92.57%, 85.96%, 85.96% and 100%, 100%, 100%, 100% at 6m, 1, 2, 3 years after treatment, respectively.
Conclusions:Comprehensive application of “capturing guide wire” and other endovascular techniques can improve the success rate of recanalization of iliac artery occlusion. Maintenance of mid-term and long-term patency of endovascular treatment requires careful follow-up and prompt treatment of restenosis and reocclusion.
