Objective To explore the technical main points of interventional treatment for occlusion of aorto-iliac-femoral artery. Methods Thirty-four patients with occlusion of aorto-iliac-femoral artery were observed after interventional treatment. There were 8 cases with the complete occlusion of inferior segment of abdominal aorta and bilateral iliac artery, including 3 cases with stenosis of renal artery. There were 23 cases with occlusion of single iliac artery, including 4 cases with occlusion of common femoral artery. There were 3 cases with occlusion of single superficial femoral artery only. They were all treated by combined interventional techniques, such as recanalization, local thrombolysis via catheter, percutaneous transluminal angioplasty (PTA), and implantation of stent. Results 8 abdominal aortas, 36 iliac arteries, 4 common femoral arteries and 3 superficial femoral arteries were all recanalized except 3 iliac arteries. The rate of patency was 94%. 46 naked stents and 3 coated stents were placed totally, including 6 abdominal aortas stents, 34 iliac artery stents, 2 common femoral artery stents, 4 superficial femoral artery stents, and 3 renal artery stents. In 31 successfully treated cases, there were 9 cases with relief of symptoms and signs and 21 cases with obvious improvement but 1 case died of long-term chronic renal failure at the 2 nd day after treatment. And complications were observed in 4 cases. All the patients were followed-up for 2-53 months (mean 21.5 months). Among them, 2 cases were treated again by interventional methods respectively at the 2 nd month and the 14 th month for reocclusion of inner stents, and symptoms in other cases showed no deterioration. Conclusion Comprehensive application of multiple-interventional techniques can be a safe and effective method in treating the occlusion of aorto-iliac-femoral artery and obtaining satisfactory clinical efficacy.
