Abstract: Objective To evaluate the methods and efficacy of interventional treatment for subclavian arterial stenosis or occlusion retrospectively. Methods From Oct 2003 to Sop 2009,25 patients with subclavian arterial lesions , including stenosis in 13 cases and occlusion in 12 cases, underwent interventional treatment. Four patients received percutaneous transluminal angioplasty (PTA) alone, and concurrent 22 stents placement were performed in 20 cases. Results The technical success rate in stenotic lesions was 100% and in occluded lesions was 91.6% with a interventional failure in 1 case. Blood pressure increased significantly after interventional treatment. The diseased side/healthy side blood pressure index increased from 0.60 ±0.11 mm Hg preoperatively to (0.95 ±0.12) mm Hg postoperatively( t = 10.53 ,P ＜0.01 ). Clinical symptoms improved, and there were no complications with strokes and embolism. 20 cases were followed up for 30 months ( from 2 months to 69 months ). Restenosis was found in 2 cases and the restenosis rate was 8.3%. The cumulative primary patency rate was 92.5% and 81.3% at 1 and 3 years,respectively. Conclusions Intervention was a less invasive and safe, effective treatment for subclavian arterial lesions.
