Coeliac trunk Flashcards
What branch ofthe abdominal aorta is the coeliac trunk
2nd branch
Where does the coeliac trunk arise from
anterior aspect of the aorta, at the aortic hiatus of the diaphragm
T12 level
What are the 3 branches of the coeliac trunk
Left gastric
Splenic artery
Common Hepatic artery
What is the course of each of the trifurcations
Two go left and one goes right
Which is the smallest of the three branches and what is it’s course
Left gastric artery, it ascends across the diaphragm giving rise to oesophageal branches
continues anteriorly along the lesser curvature of the stomach
where does the left gastric anastamose
lesser curvature of the stomach with the right gastric artery
What is the splenic artery contained within
spelnorenal ligament
how many brnaches of the splenic artery supply the spleen
5
Branches of the splenic artery
left gastroepiploic, short gastric and pancreatic
what does left gastroepiploic supply
greater curvature of stomachw
what does left gastroepiploic anastamose with
right gastroepiploic
what does short gastric supply
5-7 branches supplying fundus of the stomach
what do the pancreatic branches of the splenic artery supply
body and tail of pancreas
what is the appearance of the splenic artery
tortuous appearance
what is the common hepatic artery supply
arterial supply to liver
what does the common hepatic artery split into
proper hepatic and gastroduodenal
where does the common hepatic artery bifurcate
superior aspect of duodenum
where does the proper hepatic ascend through
lesser omentum towards the liver
what does proper hepatic branch into
right gastric, right and left hepatic and cystic artery
what does right gastric supply
pylorus and lesser curvature of the stomach
what does right and left hepatic supply
divide inferior to the porta hepatis and supply lobes of liver
where does cystic artery come from
branch of right hepatic artery - supplies gallbladder
course of gastroduodenal artery
descends posterior to the superior portion of duodenum
branches of gastroduodenal
right epiploic, superior pancreaticoduodenal
what does right gastroepiploic supply
greater curvature of stomach, greater omentum
found between layers of greater omentum
what does the superior pancreaticoduodenal supply
divdes into anterior and posterior branch which supplies head of pancreas
describe the pancreaticoduodenal arcade
network of arteries surrounding and supplying head of pancreas
There are two main arteries – each has an anterior and posterior branch, that anastomose (e.g. anterior to anterior) forming a ring structure:
Superior pancreaticoduodenal– a branch of the gastroduodenal artery.
Inferior pancreaticoduodenal – branch of superior mesenteric artery (SMA).
vessel relation to peptic ulcer
Peptic ulcers in the stomach and duodenum have potential to cause significant gastrointestinal bleeding if they erode into neighbouring arteries (usually the gastroduodenal artery).
coeliac trunk compression syndrome
The median arcuate ligament (the fibrous anchor of the diaphragm that forms the aortic hiatus) occasionally lies anterior to the coeliac trunk, rather than its usual superior position.
This can cause compression of the coeliac trunk that may present pathologically as pain. The pain is thought to be caused by the resulting ischemia of the abdominal organs -though it also may be associated with compression of the coeliac ganglia.
The treatment of coeliac trunk compression syndrome is the surgical division of the median arcuate ligament.
