Celiac trunk

• Supplies the liver, pancreas, stomach, and spleen with oxygenated blood.

Three main branches:

Left gastric artery travels to the stomach:

• Esophageal branches

Splenic artery travels to the spleen:

• Short gastric artery
• Left gastro-omental artery

Common hepatic artery travels to the liver, stomach, and abdomen.

• Gastroduodenal artery
  – Superior pancreaticodudenal artery
  – Right gastro-omental artery
• Hepatic artery proper
  – Right gastric artery (varies)
  – Left hepatic artery
  – Right hepatic artery -> Cystic artery

Clinical Correlation:

In celiac artery compression syndrome (aka, Dunbar’s syndrome), compression of the celiac trunk, usually by the median arcuate ligament of the diaphragm, reduces blood flow and causes abdominal pain after eating.
