摘　　要：目的 :探讨彩色多普勒血流显像技术 (CDFI)评估移植肾动脉狭窄经皮血管成形术 (PTRA)和支架植入术 (PTRAS)疗效的应用价值。方法 :对 11例移植肾肾动脉狭窄者于介入治疗前、后行 CDFI检查并每隔 3～4个月随访复查 ,取多普勒参数肾内段动脉血流加速度 (Ac)和主肾动脉峰速度 (Vp)进行统计学分析。结果 :介入治疗后 Ac显著增加 ,Vp明显减低 ,治疗前后差异有显著性意义 (P<0 .0 1)。植入的支架呈并行相间的线样回声 ,支架出、入口血流速度最高 ,依次大于支架内、大于支架外流速。术后并发症包括支架脱落、假性动脉瘤、静脉血栓和再狭窄 ,均经 CDFI准确诊断从而得以及时处理。结论 :CDFI检查是评价移植肾动脉狭窄介入治疗近、远期疗效和诊断并发症的理想。Objective:To ivestigate the applicational value of color Doppler flow imaging(CDFI)technique,which was used to assess the effects of percutaneous transluminal renal angioplasty(PTRA)and percutaneous transluminal renal stenting(PTRAS)for transplant renal stenosis.Methods:Eleven cases with transplant renal artery stenosis underwent CDFI examination before and after interventional treatment followed up every 3～4 months.Statistic method was used to analyse the acceleration of the intrarenal segmental artery(Ac)and the peek velocity of the main renal artery(Vp).Results:There was a significant increase in Ac and decrease in Vp after the interventional treatment.There were signficant differences before and after treatment( P <0 01).The implant stent showed parallel intermittent string like echoes.The speed of the blood flow was the highest at the inlet and outlet,and was sequentially higher than that within and out of the stent.Complications of the operation including stent escape,pseudoaneurysm,vein thrombosis and restenosis,which were diagnosed accurately by CDFI technique were treated exactly in time.Conclusions:CDFI technique is one of the ideal and reliable methods used to assess the near and far effecs and to diagnose the complications of interventional treatment for transplant renal artery stenosis.
