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.

摘要

在4例肝硬化患者的多普勒超声检查中，左胃静脉显示出异常的往返波形。每位患者的往返波形模式各不相同：病例1中，单一波形内同时出现向肝血流和离肝血流；病例2中，观察到血流方向改变且血流中断；病例3和4中，分别观察到血流方向改变但无血流中断以及进食后血流方向改变。这些波形可能代表门静脉高压患者门静脉系统分流发展过程中的一个过渡阶段。
