多普勒能量图监测移植肾急性排斥

Color Doppler energy in the monitoring of acute rejection after renal transplantation

为探讨彩色多普勒能量图（ＣＤＥ）在监测移植肾急性排斥中的应用价值，对７１例移植肾作ＣＤＥ及常规彩色多普勒血流成像（ＣＤＦＩ）等检查，其中２２例经临床及病理证实发生了急性排斥（ＡＲ）。结果表明：根据ＣＤＥ可以诊断急性排斥，其灵敏度比ＣＤＦＩ高。若ＣＤＥ与ＣＤＦＩ结合，则诊断ＡＲ的准确性更进一步提高。多次ＣＤＥ检查动态观察移植肾可预测ＡＲ的转归和监测抗排斥的效果。认为ＣＤＥ检查是目前肾移植术后较实用的一种监测手段。

Color Doppler energy (CDE) and conventional color Doppler flow imaging (CDFI) examinations of the renal allograft were performed for 71 patients after renal transplantation. Acute rejection (AR) was noted in 22 and was verified both clinically and pathologically. The sensitivity of CDE has been higher than that of CDFI in detecting AR and when the two were used combinedly the accuracy of detecting AR would be increased further. Furthermore, repeated evaluation of the transplanted kidney may help assessing the prognosis of AR and the effectiveness of antirejection treatment.
