The hepatoduodenal ligament is a thick anatomical structure wrapped in the peritoneum that constitutes part of the lesser omentum. The hepatoduodenal ligament runs from the porta hepatis to the proximal 2 cm of the duodenum. The hepatic artery proper, common bile duct, and portal vein run through the ligament near its free edge to reach the liver. These 3 structures are often referred to as the portal triad. The hepatic artery proper is a branch of the common hepatic artery originating from the celiac trunk. The hepatic portal vein is the main drainage site of the spleen and the small and large intestines. It brings nutrient-rich but oxygen-poor blood from these organs via the splenic, superior, and inferior mesenteric veins. The common bile duct is a tube-like structure that helps carry bile from the gallbladder to the lumen of the duodenum. It forms from unifying the cystic duct from the gallbladder and the common hepatic duct. These 3 important structures exist within the hepatoduodenal ligament. Understanding the location, content, and function of the hepatoduodenal ligament is important when pathology arises or performing surgery in surrounding structures. See Abdominal Cavity Organs.
肝十二指肠韧带是包裹在腹膜内的一个厚实的解剖结构，构成小网膜的一部分。肝十二指肠韧带从肝门延伸至十二指肠近端2厘米处。肝固有动脉、胆总管和门静脉在韧带的游离缘附近穿过韧带以到达肝脏。这三个结构常被称为肝门三联。肝固有动脉是发自腹腔干的肝总动脉的分支。肝门静脉是脾脏以及小肠和大肠的主要引流部位。它通过脾静脉、肠系膜上静脉和肠系膜下静脉从这些器官输送富含营养但缺氧的血液。胆总管是一个管状结构，有助于将胆汁从胆囊输送到十二指肠腔。它由胆囊的胆囊管和肝总管汇合而成。这三个重要结构存在于肝十二指肠韧带内。当周围结构出现病变或进行手术时，了解肝十二指肠韧带的位置、内容物和功能很重要。见腹腔器官。
