What does hepatoduodenal ligament contain?
[7] The hepatoduodenal ligament has lymphatic pathways, which will flow into the Pecquet cistern at a sub-diaphragmatic level. It also has the name “pars tensa” of the small omentum; its thickness contains the portal triad, that is, the portal vein, the hepatic artery, and the common bile duct.
What goes through the hepatoduodenal ligament?
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 three structures are often referred to as the portal triad.
What is the name of the space deep to the hepatoduodenal ligament?
The porta hepatis is a deep fissure in the inferior surface of the liver through which all the neurovascular structures (except hepatic veins) and hepatic ducts enter or leave the liver 1. It runs in the hepatoduodenal ligament and contains: common hepatic ducts (anterior to the right)
What is the importance of hepatoduodenal ligament?
It connects the porta hepatis of the liver to the upper border of the first part of the duodenum. Held within the hepatoduodenal ligament are the bile duct, proper hepatic artery and the hepatic portal vein; collectively known as the portal triad.
Is the hepatoduodenal ligament part of the lesser omentum?
The part of the lesser omentum running between the liver and the stomach is the hepatogastric ligament and the part between the liver and duodenum is the hepatoduodenal ligament.
What is gastrosplenic ligament?
The gastrosplenic ligament is a rather thin delicate structure that connects the superior third of the greater curvature of the stomach to the splenic hilum. This ligament contains the left gastroepiploic and short gastric vessels and their associated lymphatics.
Why is the ligament of Treitz an important surgical landmark?
Helps anchor the duodenum (first part of the small intestine, just after the stomach). Is an important landmark in human anatomy, especially for surgeons. It forms the boundary between the upper GI tract to the lower GI tract and helps define what classifies as an upper or lower gastrointestinal bleed.
What is ligamentum venosum derived from?
The ligamentum venosum, also known as Arantius’ ligament, is the fibrous remnant of the ductus venosus of the fetal circulation. Usually, it is attached to the left branch of the portal vein within the porta hepatis. It may be continuous with the round ligament of liver.
