WebJan 9, 2009 · Color Doppler examination of changes in hepatic venous waveforms is being evaluated as a means of prediction of severity of portal hypertension and presence of esophageal varices. Normal hepatic venous waveform shows a triphasic pattern. In cirrhosis, this pattern changes to a biphasic or monophasic pattern. WebJan 8, 2014 · “Triphasic: having three phases or variations; commonly referred to as a normal arterial waveform, forward flow in systole, brief reverse flow, and a third forward component (multiphasic)” “Monophasic: a monophasic pattern as a readily distinguishable systolic pulse but lack of oscillatory activity during diastole. express js library
