What level does the coeliac trunk arise?
Around T12 after aorta pierces diaphragm
Where does the coeliac trunk originate?
Off aorta, one of first branches
3 major branches of coeliac trunk
Splenic artery
Common hepatic artery
Left gastric artery
What does the splenic artery become and supply?
Supplies body, tail and neck of pancreas as it passes behind stomach
Near spleen gives off short gastric vessels supplying fundus of stomach
Gives off left gastroepiploic artery (joining R to supply greater curve stomach)
Course and branches of common hepatic
Gives off gastroduodenal branch
Then becomes proper hepatic giving off R and L hepatic arteries
What does the R hepatic artery branch into?
Cystic artery - supplies gall bladder
What does the gastroduodenal artery branch to?
Superior pancreatic duodenal artery
Right gastroepiploic artery -anastomosing with L to supply greater curve stomach
What arises from proper hepatic artery usually?
Right gastric artery - anastomoses with L from coeliac trunk to supply lesser curve of stomach
What artery supplies lesser curve of the stomach?
Left and right gastric arteries
What artery supplies greater curve of the stomach?
Right and left gastroepiploic arteries
What artery supplies pancreas?
Splenic artery supplies tail, neck and body
Superior pancreaticoduodenal artery (from gastroduodenal artery off common hepatic)
Parts on pancreas
Head
Uncinate process (nestled into C shape duodenum below head)
Neck
Body
Tail
When does the duodenum become retroperitoneal?
1st part is intraperitoneal
other parts are retroperitoneal, then comes up when jejunum begins
Is the whole pancreas retroperitoneal?
Yes apart from the tail - attaches to spleen and comes infront
The rest is behind the stomach
Superior mesenteric artery relationship with pancreas
Superior mesenteric artery passes behind neck of pancreas
Then comes anterior to uncinate process
What 5 things are at the transpyloric plane level?
Portal veins
Superior mesenteric artery
Hilum of kidney
Neck of pancreas
Fundus of gall bladder
(pyloric sphincter obvs)
What level is the transpyloric plane?
L1
4 lobes of liver
Right lobe
Left lobe
(anterior)
Quadrate (near gall bladder)
Caudate (more superior)
(posterior)
What forms the hepatic portal vein?
Splenic vein
Superior mesenteric vein
Gastric veins
Inferior mesenteric vein drains into splenic
