摘要(Abstract)：
目的探讨左主干病变裸支架治疗后再狭窄的可能原因。方法回顾性分析自1997年到2004年间行无保护左主干病变介入治疗并进行冠状动脉造影随访的18例患者的病变情况及其远期疗效。结果(1)9例双支架置入患者中,药物支架V型支架术的6例患者中有4例发生了再狭窄,再狭窄均发生在前降支和回旋支血管开口处;裸支架T支架术的2例患者发生了再狭窄,其中1例弥漫性再狭窄,另外1例发生了回旋支开口的再狭窄。(2)9例置入单个支架的患者中,5例患者支架跨过了回旋支开口,即采取了Cross-over技术,复查时只有1例左主干支架发生了再狭窄;3例左主干体部支架的患者中1例发生了弥漫性再狭窄。(3)对两例V支架的患者进行了血管内超声检查,发现在开口处没有完全膨胀,亦没有完全贴壁。结论(1)左主干病变介入治疗(特别是双支架置入方法)的再狭窄率很高。(2)在左主干分叉病变治疗中,支架跨过回旋支患者的远期预后良好,即支架可以安全地跨过回旋支。
