摘要(Abstract):
目的研究切割球囊在冠状动脉介入治疗中的有效性和安全性。方法22例病人,23支病变冠状动脉,25处病变,其中支架内再狭窄17例、18支血管、18处病变,距前次介入治疗平均(7.6±3.5)个月,使用切割球囊对病变进行扩张,观察扩张效果并进行临床门诊随访。结果全部病变均取得成功,平均扩张次数(5.2±2.3)次,平均球囊总充盈时间(233.9±94.8)s,平均最大扩张压力(9.4±1.9)大气压,术后血管狭窄程度明显减轻[(89.6±8.7)%vs(17.6±17.1)%,P=0.001],无严重并发症发生,再狭窄病变中有3处需使用普通球囊补充扩张,1处因原支架出口处撕裂再次置入支架,初次介入治疗者,因明显内膜撕裂或残余狭窄需置入支架者3例。临床随访0.5-20(7.4±6.9)个月,有2例出现心绞痛复发。结论切割球囊对冠状动脉狭窄尤其是支架内再狭窄是有效、安全的介入治疗方法。
