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.

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、可靠方法

Objective To analyze the value and pitfalls of color duplex ultrasound (US) in detecting renal artery stenosis (RAS) in native and transplant kidneys. Methods US results of suspected RAS in 30 native kidneys (17/30 positive and 13/30 negative) and 14 transplant kidneys (14/14 positive) were retrospectively compared with angiography and/or MRA. The renal artery velocity and intrarenal Doppler parameters (acceleration time [AT], acceleration index [AI], resistive index [RI]) were compared pre and post percutaneous...

Objective To analyze the value and pitfalls of color duplex ultrasound (US) in detecting renal artery stenosis (RAS) in native and transplant kidneys. Methods US results of suspected RAS in 30 native kidneys (17/30 positive and 13/30 negative) and 14 transplant kidneys (14/14 positive) were retrospectively compared with angiography and/or MRA. The renal artery velocity and intrarenal Doppler parameters (acceleration time [AT], acceleration index [AI], resistive index [RI]) were compared pre and post percutaneous transluminal renal artery angioplasty and stent placement (PTRAS). Results There were 2 false positive and 2 false negative US diagnoses of RAS in native kidneys. There was no false US diagnosis of RAS in transplant kidneys. The velocity of renal artery and parameters of the intrarenal arteries were remarkably changed after revascularization. Conclusion Even with its limitations, color duplex ultrasound is still a valuable initial imaging technique for suspected RAS. It is also useful for monitoring arterial reperfusion after correction of RAS. Combining all of quantitative measurements, qualitative Doppler waveform characteristics of the renal artery and intrarenal arteries and related clinical information would help us correctly interpret US study.[

目的 探讨彩色多普勒超声在检测自体肾和移植肾肾动脉狭窄 (RAS)中的价值和局限性。方法 回顾性对照分析了临床可疑RAS的 30例自体肾和 14例移植肾的彩色多普勒超声 (US)与磁共振动脉造影 (MRA)及动脉血管造影的结果。并将狭窄肾动脉扩张 /再通术前后的肾动脉血流速度 ,肾内小动脉多普勒波形特征 (升速时间 AT ,升速指数 AI ,阻力指数 RI)进行了比较。结果  30例自体肾RAS的超声诊断中有 2例假阳性和 2例假阴性。 14例移植肾RAS阳性的超声检查无误差。肾动脉血流速度和肾内小动脉的多普勒波形在RAS纠正术前后有显著改变。结论 尽管彩色多普勒超声在检测RAS中有局限性 ,其仍被列为对可疑RAS病例的初步影像检查 ,并在观测随访RAS纠正术后的肾血流灌注及狭窄复发中有重要作用。综合分析肾动脉及肾内动脉的血流速度和多普勒波形特征并参考有关临床资料有助于提高超声诊断RAS的准确性。

Objective To establish a new criterion about Color Doppler Ultrasound(CDUS) in the diagnosis of transplant renal artery stenosis(TRAS) by using multiple index.Methods Twenty TRAS patients were analyzed as TRAS group retrospectively verified by digital subtraction angiography(DSA).Four CDUS indexes,including the peak systolic velocity(PSV) in the renal artery,a ratio of the PSV in the renal artery to that in the external iliac artery(RIR),a ratio of the PSV in the renal artery to that in the interlobar arteries(the POST-PSV ratio) and the resistent index(RI) in the interlobar arteries were compared with those of the control group.Results Statistical significances were identified between all the 4 indexes of the two groups.Using this new criterion,CDUS had a sensitivity of 100% and a high specificity in the diagnosis of TRAS.Conclusion This new criterion can improve the validity of CDUS in the diagnosis of TRAS.

目的探讨运用多项彩色多普勒超声(CDUS)指标综合诊断移植肾肾动脉狭窄(TRAS)的的新标准。方法回顾性分析20例经数字减影血管造影(DSA)证实的TRAS的CDUS指标:移植肾肾动脉收缩期峰值血流速度(PSV)、肾动脉与髂外动脉PSV比值(RIR)、肾动脉与叶间动脉PSV比值(峰值流速后比)和叶间动脉阻力指数(RI);并与对照组相应指标对比。结果TRAS组与对照组的上述4项指标之间均存在显著统计学差异(P<0.001)。新标准具有良好的敏感性(100%)和较高的特异性。结论新标准能够提高CDUS对TRAS的诊断率。
