Porta hepatis

Last revised by Assoc Prof Craig Hacking on 18 Oct 2022

The porta hepatis, also known as the transverse hepatic fissure, is a deep fissure in the inferior surface of the liver through which all the neurovascular structures (except hepatic veins) and also hepatic ducts enter or leave the liver 1. It runs in the hepatoduodenal ligament and contains:

It also transmits the hepatic plexus of autonomic nerves:

From anterior to posterior, these structures lie in the order of duct-artery-vein thus the hepatic ducts are more accessible in surgery. The porta hepatis provides attachment for the lesser omentum. It lies between caudate lobe posteriorly and quadrate lobe anteriorly.
