1
Q

What level does the coeliac trunk arise?

A

Around T12 after aorta pierces diaphragm

2
Q

Where does the coeliac trunk originate?

A

Off aorta, one of first branches

3
Q

3 major branches of coeliac trunk

A

Splenic artery

Common hepatic artery

Left gastric artery

4
Q

What does the splenic artery become and supply?

A

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)

5
Q

Course and branches of common hepatic

A

Gives off gastroduodenal branch

Then becomes proper hepatic giving off R and L hepatic arteries

6
Q

What does the R hepatic artery branch into?

A

Cystic artery - supplies gall bladder

7
Q

What does the gastroduodenal artery branch to?

A

Superior pancreatic duodenal artery

Right gastroepiploic artery -anastomosing with L to supply greater curve stomach

8
Q

What arises from proper hepatic artery usually?

A

Right gastric artery - anastomoses with L from coeliac trunk to supply lesser curve of stomach

9
Q

What artery supplies lesser curve of the stomach?

A

Left and right gastric arteries

10
Q

What artery supplies greater curve of the stomach?

A

Right and left gastroepiploic arteries

11
Q

What artery supplies pancreas?

A

Splenic artery supplies tail, neck and body

Superior pancreaticoduodenal artery (from gastroduodenal artery off common hepatic)

12
Q

Parts on pancreas

A

Head
Uncinate process (nestled into C shape duodenum below head)
Neck
Body
Tail

13
Q

When does the duodenum become retroperitoneal?

A

1st part is intraperitoneal
other parts are retroperitoneal, then comes up when jejunum begins

14
Q

Is the whole pancreas retroperitoneal?

A

Yes apart from the tail - attaches to spleen and comes infront

The rest is behind the stomach

15
Q

Superior mesenteric artery relationship with pancreas

A

Superior mesenteric artery passes behind neck of pancreas
Then comes anterior to uncinate process

16
Q

What 5 things are at the transpyloric plane level?

A

Portal veins
Superior mesenteric artery
Hilum of kidney
Neck of pancreas
Fundus of gall bladder
(pyloric sphincter obvs)

17
Q

What level is the transpyloric plane?

A

L1

18
Q

4 lobes of liver

A

Right lobe
Left lobe
(anterior)

Quadrate (near gall bladder)
Caudate (more superior)
(posterior)

19
Q

What forms the hepatic portal vein?

A

Splenic vein
Superior mesenteric vein
Gastric veins

Inferior mesenteric vein drains into splenic
