Celiac Trunk Anatomy, Diagram & Function | Body Maps - Healthline
The first major branch of the abdominal aorta, the celiac trunk is responsible for supplying oxygen-rich blood to the stomach, spleen, liver, esophagus, and also parts of the pancreas and duodenum.
What are the three branches of the celiac trunk?
The three major branches of the celiac trunk include the left gastric, splenic, and common hepatic arteries. These arteries constitute the main blood supply to the foregut and the spleen. The left gastric artery gives off esophageal branches that supply the lower part of the esophagus. It then travels along the lesser curvature of the stomach to form an anastomosis with the right gastric artery. The splenic artery travels posterior to the stomach and gives rise to the left gastroepiploic artery, which supplies the greater curvature of the stomach. It also gives rise to pancreatic branches that supply the tail and body of the pancreas. The short gastric artery is another branch of the splenic artery, and it supplies blood to the fundus of the stomach. It is important to note that the short gastric artery does not anastomose with any other arteries. As a result, the fundus of the stomach does not have a dual blood supply, and any obstruction to the splenic artery will lead to ischemia of the fundus. [1]
How many branches does the celiac tree have?
The celiac trunk classically divides into three major branches:
What is the importance of the celiac trunk?
Most patients present with asymptomatic vascular anomalies of the celiac trunk. However, vital knowledge of the celiac trunk, its branches, and vascular variations is essential for any surgical procedures involving the upper abdomen. These procedures include a liver transplant, diagnostic procedures like angiography for gastrointestinal bleeding, or celiac axis compression syndrome. Recognition of variations in abdominal arteries that supply the liver, pancreas, gallbladder, and spleen can help in reducing the blood loss during surgical procedures involving these areas. [6][7]The vascular anatomy of the celiac trunk also plays a crucial role in arterial anastomoses during surgery.
What are the three main arterial systems?
Arising from the dorsal aorta are paired ventral segmental arteries, some of which fuse to form the median vessels. These vessels then give rise to the three main arterial systems: celiac trunk, superior mesenteric artery, and inferior mesenteric artery.
What are the ganglia of the celiac trunk?
Celiac ganglia are two nerve bundles located around the celiac trunk at the T12-L1 spinal levels. They represent a mass of nerve cell bodies that are part of the autonomic nervous system and are responsible for innervation of the gastrointestinal tract and abdominal organs. They carry sympathetic input to abdominal parenchyma and are vital for coordinating digestive functions of the gastrointestinal tract, including motility, secretion, and absorption. [4]
Which artery supplies oxygen-rich blood to the spleen?
The first major branch, which comes off anteriorly at the T12 level, is the celiac trunk. It supplies oxygen-rich blood to the spleen, and structures derived from the embryonic foregut.
