We classified the Doppler waveform of the hepatic vein into three patterns according to their morphologic characteristics. Type 1 was presented as a pulsatile flow pattern with reversed phase. Type 2 was a pulsatile flow pattern without a reversed phase, and Type 3 revealed a continuous flow pattern with or without fluttering. We analyzed the Doppler waveform of the right hepatic vein (RHV) using Duplex Doppler equipment in 21 patients with chronic hepatitis (CH), 27 patients with liver cirrhosis (LC), and 18 normal subjects. Patients with CH and LC most frequently showed Type 2 and Type 3 waveform patterns of the RHV, while 16 cases (89%) of normal subjects showed Type 1. In addition, the three waveform patterns correlated with several liver function tests using indocyanogreen test, serum albumin, and cholinesterase. The retention rate of indocyanogreen at 15 minutes was significantly higher, and serum albumin and cholinesterase were lower in Type 2 and 3 patterns. In conclusion, it seems that the different Doppler waveform patterns of the RHV provide useful data, thereby assisting evaluation of chronic liver diseases.
