Abstract

Spontaneous portosystemic shunt (SPSS) refers to collateral vessels that communicate between the portal vein system and systemic circulation. SPSS mainly includes esophageal varices, gastric varices, left gastric vein, recanalized paraumbilical vein, abdominal wall varices, and spontaneous splenorenal shunt. SPSS contributes to the development of hepatic encephalopathy caused by portal vein inflow bypassing and carries a higher risk of death in liver cirrhosis. Abdominal contrast-enhanced computed tomography is a major imaging approach to establish a diagnosis of SPSS and evaluate its location and feature. This review primarily describes the main contrast-enhanced CT features of SPSS in liver cirrhosis.

肝硬化自发性门静脉分流的计算机断层扫描图像
自发性门静脉分流(SPSS)是指门静脉系统与全身循环之间沟通的侧支血管。自发性门静脉分流主要包括食管静脉曲张、胃静脉曲张、胃左静脉、脐旁静脉再通、腹壁静脉曲张和自发性脾肾分流。自发性脾肾分流术会导致门静脉血流旁路引起的肝性脑病,并增加肝硬化患者的死亡风险。腹部造影剂增强计算机断层扫描是确定 SPSS 诊断、评估其位置和特征的主要成像方法。本综述主要介绍肝硬化 SPSS 的主要对比增强 CT 特征。
