摘要(Abstract):
目的前降支(left anterior descend ing artery,LAD)口部病变介入治疗需用支架准确定位置入,回顾性分析本中心利用Szabo技术处理LAD口部病变数据,探讨Szabo技术治疗LAD口部病变的可靠性和疗效。方法自2009年5月至2011年2月,共对15例患者LAD口部病变运用Szabo技术治疗,其中男性11例,女性4例,年龄(58±10)岁。13例因支架定位于LAD口部时明显移位采取Szabo技术进行支架定位,2例因前三叉LAD根部与回旋支(left c ircum flex artery,LCX)根部重叠致LAD口部位置不能准确判断采用Szabo技术进行支架定位,其中1例患者术前、术后均采用血管内超声检查。8例患者术后6~9个月后造影复查。结果所有患者术中均未发生支架脱载,回旋支口部术前直径与术后直径对比为(3.41±0.36)mm比(3.21±0.65)mm。与支架术后即刻对比,造影复查显示左主干(leftm ain artery,LM)末段直径为(4.10±0.24)mm比(4.12±0.23)mm;LAD口部直径为(3.09±0.28)mm比(3.23±0.24)mm;LCX口部直径为(3.09±0.85)mm比(3.11±0.93)mm。15例患者术后均无心绞痛发作。结论 Szabo技术处理LAD口部病变可以实现支架准确定位,支架置入即刻不会对LCX口部形成明显挤压,支架的边缘效应不能引起LM末段、LCX口部再狭窄。
