Duplex ultrasound was performed on 21 patients with renal transplants to assess the feasibility of detection of complications and, in particular, acute rejection and vascular abnormalities. A comparison of the results of Doppler waveform analysis in the transplant renal artery and morphological features on real time scanning in the detection and follow up of acute rejection was made. It was noted that there were characteristic alterations of Doppler shift spectral pattern in acute rejection, and these characteristics were more accurate, appeared earlier and showed a more consistent response to anti-rejection treatment than morphological changes demonstrated by real time ultrasound. Three patients had vascular abnormalities correctly predicted by duplex ultrasound and confirmed by angiography. These findings suggest that duplex ultrasound should be the investigation of choice in the initial assessment and follow up of renal transplant.
对21例肾移植患者进行了双功超声检查，以评估检测并发症的可行性，尤其是急性排斥反应和血管异常。对移植肾动脉多普勒波形分析结果与实时扫描的形态学特征在急性排斥反应检测和随访中的情况进行了比较。结果发现，急性排斥反应时多普勒频移频谱模式有特征性改变，这些特征比实时超声显示的形态学改变更准确、出现更早，且对抗排斥治疗的反应更一致。3例血管异常经双功超声正确预测并经血管造影证实。这些发现表明，双功超声应作为肾移植初始评估和随访的首选检查方法。
