摘要 目的研究比较非顺应高压球囊与普通球囊在中重度冠脉钙化病变介入治疗中作用。方法收集2005~2006年间普通球囊预处理中重度冠脉钙化病变35例与2007~2008年间非顺应高压球囊预处理中重度冠脉搏钙化病变32例,两组的性别、年龄、危险因素基本一致,前者用普通球囊预处理,球囊直径参照病变血管直径,通常为2.0~2.5mm,长度不超过病变范围,压力常为8~14atm。后者用非顺应性高压球囊压力滴定(压力以2atm渐增)序贯预处理,球囊直径参照病变血管直径,通常为3.0mm,长度为10~15mm,压力为8~14atm;如大直径球囊不能通过,可先用小球囊预扩。预扩的终止标准以充分预扩张、支架能顺利通过为准。两组支架置入后根据情况再行高压后扩张。结果非顺应性高压球囊预处理组手术成功率高于普通球囊预处理组(97%vs83%,P<0.05),而且残余狭窄、并发症(球囊破裂、冠脉夹层、无复流)较普通组也有降低趋势。结论我们认为对冠脉中重度钙化病变预处理时,如果没有旋磨装置,应用非顺应性高压球囊预处理,可以提高手术成功率,增加手术安全性。
