Doppler waveform pattern changes in a patient with primary Budd-Chiari syndrome before and after angioplasty.
A 34-year-old woman was admitted for treatment of esophageal varices. Seven years earlier, she had been diagnosed with Budd-Chiari syndrome, and percutaneous transluminal angioplasty (PTA) for right hepatic vein (RHV) stenosis was done. On admission, Doppler sonography showed a flat waveform in the RHV. RHV re-stenosis was confirmed on X-ray sonography. After PTA, the stenosis improved. Heterogeneous liver enhancement on enhanced computed tomography became homogeneous, her esophageal varices became inconspicuous, and the flat Doppler waveform pattern changed to a triphasic pattern. Doppler sonography was very useful for evaluating the effect of angioplasty and to diagnose re-stenosis.
