Quick Facts
Origin: Umbilical part of left branch of the hepatic portal vein.
Course: Travels anterior and slightly inferior from the left branch of the hepatic portal vein to enter segment IV of the liver.
Branches: None.
Structures Supplied: Segment IV of the liver.
Origin
The segmental IV vein originates from the umbilical part of the left branch of the hepatic portal vein.
Course
After branching from the umbilical part of the left branch of the hepatic portal vein, the segmental IV vein travels anteriorly and slightly inferior to enter segment IV of the liver. This vein continues to branch into smaller venous branches, which ultimately terminate as portal venules. These portal venules drain into the hepatic sinusoids.
Branches
There are no named branches.
Supplied Structures
The segmental IV vein supplies nutrient-rich venous blood from the digestive tract to segment IV of the left liver.
