Encyclopedia
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:
Collectively, these structures are known as the portal triad

Running inside it are the following:
- hepatic artery properHepatic artery properThe hepatic artery proper , arises from the common hepatic artery and runs alongside the portal vein and the common bile duct to form the portal triad. The hepatic artery proper gives off a small supraduodenal artery to the duodenal bulb...
- hepatic portal veinHepatic portal veinThe hepatic portal vein is not a true vein, because it does not conduct blood directly to the heart. It is a vessel in the abdominal cavity that drains blood from the gastrointestinal tract and spleen to capillary beds in the liver...
- common bile ductCommon bile ductThe common bile duct is a tube-like anatomic structure in the human gastrointestinal tract. It is formed by the union of the common hepatic duct and the cystic duct . It is later joined by the pancreatic duct to form the ampulla of Vater...

Portal triad
A portal triad is a distinctive arrangement in the liver. It is a component of the hepatic lobule. It consists of the following five structures:* hepatic artery* hepatic portal vein* bile duct*lymphatic vessels...

Pringle manoeuvre
The Pringle manoeuvre is a surgical manoeuvre used in some abdominal operations. A large haemostat is used to clamp the hepatoduodenal ligament interrupting the flow of blood through the hepatic artery and the portal vein and thus helping to control bleeding from the liver.Should bleeding though...
