Where does the hepatoduodenal ligament attach?
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.
Where is the ligamentum venosum located?
liver
The ligamentum venosum lies within a fissure on the inferior surface of the liver between the caudate lobe posteriorly and the left lobe anteriorly, where it is also invested by the peritoneal folds of the lesser omentum (gastrohepatic ligament).
Which artery can be used as a landmark to identify the hepatoduodenal ligament?
The hepatoduodenal ligament is the portion of the lesser omentum extending between the porta hepatis of the liver and the superior part of the duodenum. Running inside it are the following structures collectively known as the portal triad: hepatic artery proper….

What 3 structures run in the free edge of the lesser omentum?
Contents. Between the two layers of the lesser omentum, close to the right free margin, are the hepatic artery proper, the common bile duct, the portal vein, lymphatics, and the hepatic plexus of nerves—all these structures being enclosed in a fibrous capsule (Glisson’s capsule).
What is the hepatoduodenal ligament?
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.
What is in the Hepatogastric ligament?
The hepatogastric ligament or gastrohepatic ligament connects the liver to the lesser curvature of the stomach. It contains the right and the left gastric arteries. In the abdominal cavity it separates the greater and lesser sacs on the right. It is sometimes cut during surgery in order to access the lesser sac.
What is the ligamentum venosum?
The ligamentum venosum is a fibrous remnant which travels superiorly from the porta hepatis of the liver to the inferior vena cava. It is often obliterated in adults.
What is ligamentum teres and ligamentum venosum?
The ligamentum venosum 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 (gateway to theliver). It may be continuous with the round ligament of liver (ligamentum teres hepatis).
What is behind the hepatoduodenal ligament?
The opening behind the free edge of the hepatoduodenal ligament is the omental foramen (foramen of Winslow), the only opening of the lesser sac, and the sole connection between the lesser sac and the greater peritoneal cavity.[5] To locate the hepatoduodenal ligament, one may start from the hepatogastric ligament and …
What is a caudate lobe?
The caudate lobe represents the only part of the liver that is in contact with the vena cava, except at the entrance of the main hepatic veins into the vena cava, and provides an anastomosis between the hepatic veins and vena cava.
Is lesser omentum part of peritoneum?
The lesser omentum, also called the small omentum or gastrohepatic omentum, is the double layer of peritoneum that extends from the liver to the lesser curvature of the stomach (hepatogastric ligament) and the first part of the duodenum (hepatoduodenal ligament).
What makes up lesser omentum?
The lesser omentum consists of two ligaments: medially located hepatogastric ligament, and laterally located hepatoduodenal ligament. The hepatogastric ligament connects the lesser curvature of the stomach to the visceral surface of the liver.
