The quadrate lobe is a rectangular area on the underside of the liver, bounded by the gallbladder fossa on the right, the fissure for the ligamentum teres on the left and the porta hepatis behind. Although it lies to the right of the falciform ligament, its blood supply and bile drainage come from the left side, so it is functionally part of the left liver. It corresponds to Couinaud segment IVb.
| Location | Inferior (visceral) surface of the liver, between the gallbladder fossa and the fissure for the ligamentum teres, in front of the porta hepatis |
|---|---|
| Parts |
|
| Nerve Supply | Hepatic plexus from the coeliac plexus (sympathetic); Vagus nerve (parasympathetic) |
| Blood Supply | Left hepatic artery (segment IV branches, sometimes a middle hepatic artery) |
| Venous drainage |
|
| Lymphatic drainage |
|
Performs normal liver functions as part of the functional left liver.
It sits directly beside the gallbladder bed, so gallbladder cancer commonly invades it and radical cholecystectomy includes resection of segments IVb and V. Its position in front of the porta hepatis means it must sometimes be lifted to expose the hepatic duct confluence.
Direct spread of gallbladder cancer into the adjacent quadrate lobe and segment V of the liver.
