摘要:
目的探讨移植肾动脉狭窄(TRAS)的介入治疗。方法35例TRAS患者从肾移植到出现肾动脉狭窄症状平均6.9个月(3~18个月),记录经皮血管成形术(PTA)前后血压变化和血肌酐水平。经对侧股动脉或左肱动脉入路,使用普通球囊导管(5F,直径4~6mm,长度20~30mm)和微球囊导管(2.6F,直径3mm,长度36mm)分别对35例TRAS行PTA术,其中11例放置支架。结果35例TRAS患者共行46次PTA(行1次PTA20例,2次12例,3次3例),其中26次经对侧股动脉,20次经左肱动脉穿刺插管。PTA治疗前肾动脉狭窄率为75%~98%,PTA后狭窄率降为10%~30%。PTA前收缩压150~210mmHg (1mmHg =0.133kPa),平均170mm Hg ,舒张压90~145mmHg ,平均120mm Hg ;PTA后收缩压降为100~190mmHS ,平均135mmHg ,舒张压降为80~125mmHg ,平均85mmHg 。首次PTA后再狭窄率39%,再次PTA后狭窄率15%。46次PTA共使用普通球囊导管26个,微球囊导管20个。11枚支架8枚为自膨式支架,3枚为球囊扩张式。术后随访3~60个月(平均23个月)。35例中最终治愈11例,改善15例,好转7例,无效2例。除1例肱动脉入路发生术后穿刺点血肿外无其他并发症。结论TRAS的PTA治疗安全有效,配合肱动脉入路和微球囊导管有助于提高手术成功率;合理选用支架能降低再狭窄率。
