The aim of this study was to analyze the clinical results of endovascular treatment for occlusion of longsegment iliac artery (>10 cm). The clinical data of endovascular treatment for 20 patients (29 limbs) with occlusion of long-segment iliac artery were performed retrospective analysis during December, 2012 and December, 2015. 15 cases were performed direct balloon-expandable stent implantation, and 5 cases were performed balloon-expandable stent implantation after thrombolysis. All patients were performed outpatient follow-up and the follow-up rate of 15 cases (18 limbs) was 75%. The re-canalizing rate of iliac artery was 100%, the combined groin following lesion re-canalizing rate was 72.7%. The average ankle-brachial index (ABI) in preoperative and postoperative week were (0.28 ± 0.12) and (0.72 ± 0.21), the difference was statistically significant (P<0.05). The follow up rate of 15 cases (18 limbs) was 83.3%, up for 3-24 months. The re-canalizing rate of iliac artery in the first phase was 94.4% (17/18), and 100% for the second. The endovascular treatment for occlusion of long-segment iliac artery was minimally invasive, effective and safe, the recent re-canalizing rate and the limb salvage rate were high, which can be used as the preferred treatment for occlusion of long-segment iliac artery.
