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. © 2007 Wiley Periodicals, Inc.
