Objective To evaluate the effi cacy of interventional treatment for stenosis-occlusion in aorta (ASO). Methods Twenty-three patients with stenosis-occlusive pathological changes in aorta were included. Among them, 14 patients were with stenosis in aorta, and 9 with occlusion in aorta. They were all treated by combined interventional techniques, such as recanalization, local thrombolysis via catheter, percutaneous transluminal angioplasty (PTA), implantation of stent, and percutaneous fenestration of intimal flap (FIF). Results The universal successful rate of the 23 cases with ASO was 96.7%. Among the 9 cases with occlusive pathological changes in aorta, the successful rate of recanalization and local thrombolysis was 100 0%. 17 cases were treated with PTA after thrombolysis, the successful rate was 91 7% (one case died of rupture of aorta during the procedure). 11 ca ses were treated with implantation of stent after PTA, the successful rate was 100 0%. One case was successfully treated with FIF and implantation of stent. Among the group, one case was dead, 18 cases′ symptom disappeared, and 4 cases′ symptom was improved. All the patients were followed-up for 1-113 months (mean 31.0 months). Among them, one case was misfollowed after 48 months, one case died of combined dissected aorta rupture after 18 months. Restenosis occurred in one case. The therapy efficacy of the other cases was stable and there was no relapse. Conclusions Comprehensive application of multi-interventional techniques can obtain a satisfactory clinical effect in treating ASO.
