Abstract
Unusual to-and-fro waveforms were demonstrated in the left gastric vein on Doppler sonograms in four patients with liver cirrhosis. The patterns of the to-and-fro waveforms were diverse in each of the patients: both hepatopetal and hepatofugal flow occurred in a single waveform in case 1, changes in the flow direction with flow interruption were noted in case 2, and changes in flow direction without observation of flow interruption and changes after meals were noted in cases 3 and 4, respectively. These waveforms may represent a transitional phase during the development of a portal systemic shunt in patients with portal hypertension.
