冠状动脉内Palmaz－Schatz支架植入术70例分析

ClinicalevaluationofintracoronaryPalmaz┐Schatzstenting(70cases)

为评价冠状动脉内Ｐａｌｍａｚ－Ｓｃｈａｔｚ支架的临床效果，我们回顾性总结分析了７０例冠心病患者７４支冠状动脉血管８０个Ｐａｌｍａｚ－Ｓｃｈａｔｚ支架植入的临床成功率、并发症及远期疗效。结果：ＤｅＮｏｖｏ支架植入６３个，Ｓｕｂｏｐｔｉｍａｌ支架植入１１个，Ｂａｉｌ－ｏｕｔ支架植入４个，再狭窄病变支架植入２个。左前降支３７处病变植入４１个支架，左回旋支１１处病变植入１１个支架，右冠状动脉２５处病变植入２７个支架，１处病变植入１个支架。支架植入的成功率为９８．７％。术中１例ＳＶＧ支架植入术中近端血管血栓形成。住院期间无亚急性支架血栓形成或严重出血性并发症。术后３～２４个月３０例患者共３３个支架接受冠状动脉造影随访，６例６个支架节段血管有再狭窄，再狭窄率为１８．７％。结果提示：冠脉内Ｐａｌｍａｚ－Ｓｃｈａｔｚ支架是一种安全有效的介入性治疗技术，其成功率高，并发症率低。
