摘要(Abstract)：
目的 评估经皮支架置入术治疗主动脉缩窄的疗效。方法 5例 [男性 3例 ,平均年龄(33± 9)岁 ]胸主动脉缩窄患者行经皮主动脉球囊成形术及支架置入术。结果 各例支架置入后即刻压力阶差显著减低为 (8± 2 )mmHg(1mmHg =0 133kPa) ,与术前 (73± 6 )mmHg比较 ,差异有显著性(P <0 0 0 1)。平均随访 (2 7± 12 )月 ,各例无需多种药物治疗但血压控制良好 ,收缩压平均为 (15 2± 7)mmHg ,舒张压 (91± 5 )mmHg ,与术前收缩压 (2 0 1± 8)mmHg、舒张压 (12 0± 8)mmHg比较 ,差异有显著性 (P <0 0 0 1) ,无不良事件发生。结论 经皮支架置入术治疗主动脉缩窄安全可行 ,且对患者血压控制具有长期疗效。
