Department of Tropical Medicine and Gastroenterology, Faculty of Medicine, Assiut University, Assiut, Egypt

View larger version (54K): [in a new window]   Figure 1. Portal vein waveform patterns. (a) PV0 with a slightly pulsatile envelope. (b) PV1 with a flat envelope.

(a) A triphasic HV0 pattern (two antegrade waves below the baseline and one pre-systolic retrograde wave above the baseline) with a narrow spectrum and a visible window. (b) HV1 with absent reversed pre-systolic wave. (c) HV2 with a flat pattern.
