同种异体肾移植术后移植肾动脉狭窄 介入治疗的临床疗效分析

目的探讨同种异体肾移植术后移植肾动脉狭窄（TRAS）介入治疗的临床疗效。方法介入治疗同种异体肾移植术后TRAS患者22例,其中单纯球囊扩张治疗10例（球囊组）,内支架治疗12例（支架组）。对所有患者术前及术后2年内血压、肾功能以及生活质量进行评估,并与同期接受单纯药物治疗的6例TRAS患者（药物组）进行比较。结果球囊组技术成功率90.00%,支架组技术成功率100%。术后在血压及肾功能改善方面,球囊组和支架组均取得显著疗效,两组近期疗效未见明显差异,药物组疗效不满意。术后随访6个月～2年,支架组再狭窄率16.67%,除1例不明原因治疗无效外,其余11例均能比较健康的生活和工作。球囊组手术失败1例,再狭窄率达40.00%。结论内支架植入术可作为TRAS特别是I型及Ⅱ型狭窄的首选治疗方法。
