Two children with clinically suspected renal vein thrombosis were evaluated by duplex Doppler sonography and colour flow imaging. Both cases presented unspecific findings with an enlarged kidney and loss of cortico-medullary delineation on gray-scale ultrasound, but an unusual flow pattern with retrograde plateau-like frequency shifts during diastole. No venous signal could be obtained. By colour flow imaging only the main renal artery and its proximal branches could be visualised with a reverberating oscillation of blood flow. In addition, partial thrombosis of inferior vena cava in one patient and iliac vein thrombosis in the other could be demonstrated. Clinical improvement during fibrinolytic therapy in one case and nephrectomy in the other case confirmed the diagnosis.
对两名临床怀疑肾静脉血栓形成的儿童进行了双功多普勒超声和彩色血流成像评估。两例病例在灰阶超声上均表现为非特异性表现，即肾脏增大且皮髓质分界消失，但舒张期出现逆行平台样频移的异常血流模式。未获得静脉信号。通过彩色血流成像，仅能看到主肾动脉及其近端分支有血流的混响振荡。此外，一例患者显示下腔静脉部分血栓形成，另一例显示髂静脉血栓形成。一例患者在溶栓治疗期间临床症状改善，另一例患者进行了肾切除术，均证实了诊断。
