Extrahepatic portal vein aneurysm is a rare clinical entity. The two most common locations for aneurysmal formation are at the confluence of the superior mesenteric vein (SMV) and the splenic vein, and at main portal vein trunk, just above the SMV-splenic vein confluence. In this article, two cases of extrahepatic portal vein aneurysm and their surgical treatment are presented. One is a saccular aneurysm located at the truncus of the portal vein; the other is a fusiform aneurysm at the confluence of the superior mesenteric vein and the splenic vein.
肝外门静脉瘤是一种罕见的临床病症。动脉瘤形成的两个最常见部位是肠系膜上静脉（SMV）与脾静脉的汇合处，以及门静脉主干，就在SMV - 脾静脉汇合处上方。本文介绍了两例肝外门静脉瘤及其手术治疗情况。一例是位于门静脉主干的囊状动脉瘤；另一例是位于肠系膜上静脉与脾静脉汇合处的梭形动脉瘤。
