Caudate lobe

The caudate lobe is a section of the liver located on the posterior side of the right lobe. It is situated between the inferior vena cava and the fissure for the ligamentum venosum.

Anatomy

The caudate lobe is a small lobe of the liver that is anatomically distinct from the right and left lobes. It is bordered by the inferior vena cava on the right, the fissure for the ligamentum venosum on the left, and the porta hepatis below. The caudate lobe is sometimes considered part of the right lobe of the liver, but it has its own blood supply and venous drainage, making it functionally distinct.

Function

The caudate lobe, like the rest of the liver, plays a role in various metabolic processes, including the detoxification of blood, protein synthesis, and the production of biochemicals necessary for digestion. It also stores glycogen, decomposes red blood cells, and produces hormones.

Clinical significance

The caudate lobe can be involved in various liver diseases, including cirrhosis and hepatocellular carcinoma. Its unique position and blood supply can make surgical interventions challenging. In cases of liver transplantation, the caudate lobe may be considered separately due to its distinct vascularization.
