目的总结逆行锁骨下动脉支架植入治疗重度锁骨下动脉狭窄和闭塞的初步临床经验方法1999年9月至2003年7月采取经肱动脉逆行植入支架治疗锁骨下动脉重度狭窄和闭塞共19例术前诊断包括彩色多普勒超声检查和动脉造影确诊手术方法是经患侧上肢肘部小切口解剖肱动脉，逆行造影和支架植入。结果本组支架植入成功18例，支架植入满意，无移位。失败1例．因病变闭塞完全，导丝无法通过闭塞部位而转行手术治疗。治疗成功的18例中随访16例，随访时间2～48个月，平均24个月失访2例。随访率88.9％一有2例分别于术后11个月和14个月出现再狭窄，1例再次行球囊扩张成功，1例转行手术治疗结论逆行锁骨下动脉支架植入是治疗锁骨下动脉重度狭窄和闭塞安全有效的方法

Preliminary assessment of retrograde endovascular stenting for subclavian artery Occlusion

Objective To investigate the preliminary clinical results of retrograde endovascular stenting for subclavian artery severe stenosis or occlusion. Methods From September 1999 to July 2003, retrograde endovascular balloon angioplasty and stent placement were performed on 19 patients suffering from severe stenosis or occlusion of subclavian artery.The retrograde endoluminal stenting procedure were performed through the brachial artery. ResultsThe procedures were technically successful in 18 of 19 patients.One case was failed and changed to bypass surgery.16 of 18 patients were followed up. The mean follow-up was 24 months (range 2-48months). During the follow-up period,2 cases developed restenosis after 11 months and 14 months, respectively. One was performed with PTA and one was treated by surgery. ConclusionRetrograde endovascular stenting for severe stenosis or occlusion of the subclavian arteries appears to be feasible and safe.
