Celiac trunk
The truncus celiacus ("abdominal cavity trunk ", from ancient Greek koila , "abdominal cavity" ), also known as the arteria coeliaca , is the first of the three unpaired intestinal branches of the abdominal aorta of mammals . It arises at the level of the aortic hiatus (approximately at the level of the 12th thoracic vertebra), a slit in the diaphragm through which the aorta passes from the thorax (chest) into the abdomen (abdominal cavity). In humans, the origin of this blood vessel is at the level of the twelfth thoracic vertebra .
Coverage area
The celiac trunk is for the arterial supply of the liver , stomach , pancreas ( pancreas ), duodenum ( the duodenum ), spleen and the adjacent Serosastrukturen responsible.
The celiac trunk divides into three main vessels, which is also known as Haller's tripod ( Tripus celiacus, Tripus Halleri ):
-
Arteria gastrica sinistra (left gastric artery)
- Rr.oesophagei (to the esophagus , esophagus)
-
Splenic artery (or splenic artery ) (splenic artery)
- Arteria pancreatica dorsalis (back pancreatic artery )
- Arteriae gastricae breves (short gastric arteries)
- Arteria gastrica posterior (artery of the gastric posterior wall)
- Arteria gastroomentalis sinistra (or A. gastroepiploica sinistra ) (left gastric reticulum artery, from ancient Greek epiploon 'network' )
-
Common hepatic artery (common hepatic artery)
-
Arteria hepatica propria (own liver artery)
- Arteria gastrica dextra (right gastric artery; in 1/3 of the cases from the arteria hepatica commonis)
- Arteriae hepaticae dextra et sinistra (right and left hepatic arteries)
- Arteria cystica (gallbladder artery )
-
Gastroduodenal artery (gastric and duodenal arteries )
- Arteria gastroomentalis dextra (or A. gastroepiploica dextra ) (right gastric reticulum artery)
- Arteria pancreaticoduodenalis superior (upper pancreatic-duodenal
- Arteria pancreaticoduodenalis superior anterior (upper anterior
- Arteria pancreaticoduodenalis superior posterior ( superior posterior pancreatic artery )
-
Arteria hepatica propria (own liver artery)
An inadvertent disruption of the tripus results in the inevitable death of the individual, its function is vital. Therefore, in the event of intestinal infarction as a result of embolism or thrombosis, the celiac trunk must always be revised in order to carry out an embolectomy if necessary .
