tortuous appearance

Question 15

proper hepatic and gastroduodenal

Question 17

where does the common hepatic artery bifurcate

Answer 17

superior aspect of duodenum

Question 18

Answer 19

right gastric, right and left hepatic and cystic artery

Question 20

Answer 20

pylorus and lesser curvature of the stomach

Question 21

what does right and left hepatic supply

Answer 21

divide inferior to the porta hepatis and supply lobes of liver

Question 22

where does cystic artery come from

Answer 22

branch of right hepatic artery - supplies gallbladder

Question 23

course of gastroduodenal artery

Answer 23

descends posterior to the superior portion of duodenum

Question 24

branches of gastroduodenal

Answer 24

right epiploic, superior pancreaticoduodenal

Question 25

what does right gastroepiploic supply

Answer 25

greater curvature of stomach, greater omentum found between layers of greater omentum

Question 26

what does the superior pancreaticoduodenal supply

Answer 26

divdes into anterior and posterior branch which supplies head of pancreas

Question 27

describe the pancreaticoduodenal arcade

Answer 27

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).

Question 28

vessel relation to peptic ulcer

Answer 28

Peptic ulcers in the stomach and duodenum have potential to cause significant gastrointestinal bleeding if they erode into neighbouring arteries (usually the gastroduodenal artery).

Question 29

coeliac trunk compression syndrome

Answer 29

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.
