肾移植急性动脉狭窄的影像学表现及介入治疗

The Imaging Features and Interventional Therapy in the Acute Strictureof Artery of Renal Transplantation

目的探讨肾移植急性动脉狭窄的影像学表现及介入治疗的价值。资料与方法 15例肾移植动脉狭窄患者均有高血压和肾功能不良。均采用股动脉插管造影,明确诊断后行球囊扩张(PTA)和/或置入支架。结果15例中,6例行PTA治疗,9例行支架置入,操作全部成功。6例PTA治疗者中2例术后1个月出现再狭窄,行支架置入;9例支架置入者1年内有1例出现再狭窄。15例肾移植动脉狭窄患者介入治疗后均有血压下降和肾功能改善。结论肾移植动脉狭窄分为受体动脉狭窄、供体肾动脉狭窄和吻合口狭窄。血管造影是诊断肾移植动脉狭窄的金指标。介入治疗应作为肾移植急性动脉狭窄的首选疗法。

Objective To discusse the value of the imaging features and interventional therapy in acute stricture of artery of renal transplantation.Materials and Methods The symptom of 15 cases,aging from 22 to 67,was hypertension and the dysfunction of renal.After angiography through femoral artery cannulation,the balloon dilatation or/and stent was performed.Results The operations in all the 15 cases,6 cases with balloon dilatation and 9 cases with stent assistant were successful.Their blood pressure descended and the renal function improved.In 2 of the 6 cases with balloon dilatation,Restenosis occured after one month,and they had stent insertion then.In the 9 cases with stent therapy,1 cases had restenosis in one year.Conclusion The stricture of artery of renal transplantation could divided into the stricture of recipient artery,the stricture of the renal artery of donor and the stricture of the stoma.The angiography was the golden standard to diagnosis the stricture of the artery of renal transplantation.The interventional therapy should be the first choice.
