摘要(Abstract):
目的评价冠状动脉西罗莫司洗脱支架治疗小直径肾动脉狭窄的长期疗效。方法 26例患者共置入32个冠状动脉西罗莫司洗脱支架(3.0~4.0mm),中位数随访时间12个月(6~36个月)。随访内容包括血压、血尿素氮、血肌酐、肌酐清除率、肾动脉造影和肾动脉彩色多普勒超声检查。结果末次随访与术前相比,23.1%的患者(6例)血压改善,11.5%的患者(3例)肾功能改善,11.5%的患者(3例)肾功能减退。26例患者中出现了2例再狭窄。该2例患者于支架术后6个月时作肾动脉彩色多普勒超声检查并未发现有支架内再狭窄,但在术后10个月和16个月时分别作血管造影和肾动脉彩色多普勒超声检查发现有支架内再狭窄。结论对于小直径肾动脉狭窄患者,置入西罗莫司洗脱支架可能会减少再狭窄。术后6个月的随访不能发现所有再狭窄病例,所以随访时限应在1年以上。
