Abstract

Hepatic "hot spots" in anterior paraumbilical hepatic segments of patients suffering from superior vena cava syndrome may be revealed by angio-computed tomography. They may be due to a collateralizing system, the epigastric-paraumbilical venous system (EPVS), which enters the liver as a "third inflow". We report a typical case emphasizing the role of the ensiform and inferior Sappey's veins which constitute typical anatomic components of the EPVS.

摘要

经血管计算机断层扫描（angiocomputed tomography），上腔静脉综合征（superior vena cava syndrome）患者前脐旁肝段的肝脏“热点”可能会显现出来。这些热点可能是由于一个侧支循环系统，即胃脐静脉系统（epigastric-parau-mbilical venous system，EPVS）所致，该系统作为“第三流入”进入肝脏。我们报告了一个典型病例，强调了剑突和下方 Sappey 静脉的作用，它们构成了 EPVS 的典型解剖成分。
