Coeliac trunk Flashcards
What does the coeliac trunk arise from?
Abdominal aorta anteriorly
Where does the coeliac trunk arise from the abdominal aorta?
Aortic hiatus of diaphragm, T12
What does the coeliac trunk do after it arises?
Divides into three branches
What are the three branches of the coeliac trunk?
Left gastric artery
Splenic artery
Common hepatic artery
Where does the left gastric artery travel after it arises?
Ascends upwards
then descends downwards along lesser curvature of from left side
Where does the splenic artery travel after it arises?
Posteriorly to the stomach
along the superior border of the pancreas
towards spleen
What does the splenic artery do as it travels towards the spleen?
Gives off branches
What are the branches of the splenic artery?
Left gastroepiploic artery
Short gastric arteries
Pancreatic branches
Where does the left gastroepiploic artery travel after it arises?
Downwards along the greater curvature of the stomach from left side
Where do the short gastric arteries travel after they arise?
Upwards along the fundus of the stomach
Where do the pancreatic branches travel after they arise?
Downwards along posterior surface of pancreas
Where does the common hepatic artery travel after it arises?
To the right towards the liver
What does the common hepatic artery do as it travels towards the liver?
Superiorly to the duodenum, it divides into two branches
What two branches does the common hepatic artery divide into?
Proper hepatic artery
Gastroduodenal artery
Where does the proper hepatic artery travel after it arises?
Ascends through lesser omentum
towards the liver
What does the proper hepatic artery do as it travels towards the liver?
Divides into three branches
What three branches does the proper hepatic artery divide into?
Right gastric artery
Right and left hepatic arteries
Cystic artery
Where does the right gastric artery travel after it arises?
Descends downwards to the pylorus and lesser curvature of the stomach from right side
Where do the right and left hepatic arteries travel after they arise?
To the right and left lobes of the liver
Where does the cystic artery travel after it arises?
Along the gallbladder
Where does the gastroduodenal artery travel after it arises?
Descends posteriorly to the superior part of the duodenum
What does the gastroduodenal artery do as it descends downwards posteriorly to the superior part of the duodenum?
Divides into two branches
What are the two branches of the gastroduodenal artery?
Right gastroepiploic artery
Superior pancreatoduodenal artery
Where does the right gastroepiploic artery travel after it arises?
Up the greater curvature of the stomach from right side
Where does the superior pancreatoduodenal artery travel after it arises?
Descends downwards anteriorly to head and neck of the pancreas
