A study of 187 consecutive patients undergoing upper abdominal ultrasound was conducted to evaluate the size and the ending of the left gastric vein (LGV) into the portal system and its relation to the coeliac axis and tributaries. The LGV was identified in 86 (46%) of these patients; the mean size of the LGV was 2.4 mm, 30% terminating in the portal vein, 33% at the splenoportal junction and 37% in the splenic vein. The LGV was anterior to the coeliac trunk and its branches in 45%, two thirds of these ending in the splenic vein and posterior in 51% of the cases, 86.3% of which ended at or to the right of the splenoportal junction. In conclusion, the variation in the site of termination of the LGV has a significant correlation with the course of the LGV in relation to the adjacent vessels. The LGV tends to cross superficial to the splenic artery when it enters the splenic vein and deep to the common hepatic artery when draining in the portal vein.
对187例连续接受上腹部超声检查的患者进行了一项研究，以评估胃左静脉（LGV）进入门静脉系统的大小、终点及其与腹腔干和属支的关系。在这些患者中，86例（46%）识别出了LGV；LGV的平均大小为2.4mm，30%汇入门静脉，33%在脾门处汇入，37%汇入脾静脉。45%的LGV位于腹腔干及其分支前方，其中三分之二汇入脾静脉；51%位于后方，其中86.3%在脾门处或其右侧汇入。总之，LGV终点部位的变异与LGV相对于相邻血管的走行具有显著相关性。LGV汇入脾静脉时倾向于从脾动脉浅面穿过，汇入门静脉时则从肝总动脉深面穿过。
