目的:探讨移植肾动脉狭窄(TRAS)的早期诊断、治疗和预后,评价综合治疗TRAS的临床效果及安全性.方法:对6例TRAS患者的临床资料作回顾性分析,并将其临床特点、诊断、疗效、并发症及转归等进行总结.所有患者均采用彩色多普勒血流显像(CDFI)进行早期筛查,双源CT三维血管成像(DSCTA)确诊为TRAS,并判断移植肾动脉狭窄部位和程度;TRAS确诊后,所有患者立即实施经皮肾血管成形术(PTRA)治疗:采用股动脉穿刺Seldinger技术,数字减影血管造影(DSA)证实移植肾动脉狭窄的部位和程度,用4～6mm球囊导管,直径选择以邻近正常血管直径为标准,在透视下将球囊导管置入狭窄动脉处,反复扩张球囊至球囊壁上切迹消失,再放置内径5mm的Sreaker支架.然后,造影了解血管成形的效果.
