Waveform analysis of arterial Doppler sonography signals is widely used in clinical practice. A characteristic, W-shaped diastolic waveform has been reported in the renal artery of renal transplant recipients in cases of renal vein thrombosis or severe acute rejection. Although Doppler sonography is widely used for the evaluation of liver transplants, we found no report of this waveform in cases of outflow block or severe acute rejection. We report the case of a patient with an adult living-donor liver transplant in whom the W-shaped sign occurred during severe acute rejection with massive liver parenchyma destruction.
动脉多普勒超声信号的波形分析在临床实践中被广泛应用。据报道，在肾移植受者发生肾静脉血栓形成或严重急性排斥反应时，其肾动脉会出现一种特征性的W形舒张期波形。尽管多普勒超声被广泛用于肝移植的评估，但我们未发现有关流出道梗阻或严重急性排斥反应时出现这种波形的报道。我们报告一例成人活体肝移植患者的病例，该患者在严重急性排斥反应伴大量肝实质破坏期间出现了W形征。
