早在19世纪就有人对脐静脉和副脐静脉进行研究,然而至今对成人中脐静脉的开放率,副脐静脉的起源、分布、与门静脉的从属关系以及脐静脉与副脐静脉间的连接仍有争议。面对门脉系统高压时左肝门静脉和腔静脉间的侧支循环,大多数放射学工作者不能肯定其为再开放的脐静脉抑为副脐静脉。为此作者取22具生前无门脉高压,连同肝圆韧带的新鲜尸体肝脏,用彩色液体硅橡胶(Microfil)灌注左肝门静脉或分别灌注左肝门静脉和左肝动脉,继而用甲基水杨酸组织透明技术使组织透明后在立体显微镜下研究脐静脉、副脐静脉的解剖及其与门静脉的关系。 22例中硅橡胶充盈脐静脉者7例,后者在肝圆韧带内笔直行走,终止于左肝门静脉主干。脐静脉充盈率
As early as the 19th century, studies on umbilical and accessory umbilical veins have been conducted. However, to date, the open rate of umbilical veins in adults, the origin and distribution of accessory umbilical veins, the subordinate relationship with portal veins and the connection between umbilical and accessory umbilical veins Still controversial. Facing the collateral circulation between the left hepatic veins and vena cava when the portal system is under high pressure, most radiologists can not be sure that it is a re-umbilical vein that is reopened for the umbilical vein. To do this, the authors took 22 non-portal hypertension patients, together with fresh liver ligaments of the liver, perfusing the left hepatic vein with Microfil or perfusing the left hepatic vein and left hepatic artery, The transparent texture of acid tissue makes the tissue transparent and the anatomy of umbilical vein and accessory umbilical vein under stereomicroscope and its relationship with portal vein. Twenty-two cases of silicone rubber filled umbilical vein in 7 cases, the latter within the round ligament straight walk, terminating in the left hepatic vein trunk. Umbilical vein filling rate
