Coeliac Trunk

Question 1

What are the 3 main branches of the Coeliac Trunk?

Answer 1

1. Left Gastric Artery.
2. Splenic Artery.
3. Common Hepatic Artery.

Question 2

What does the Left Gastric Artery Supply?

Answer 2

Oesophagus and Lesser Curvature of the stomach.

Question 3

Where does the Coeliac Trunk arise?

Answer 3

Anterior aspect of the aorta at the aortic hiatus of the diaphragm at T12. Divide 1cm before dividing into 3.

Question 4

Describe the course of the Left Gastric Artery.

Answer 4

Ascends the diaphragm and divides into the oesophageal branches before continuing anteriorly along the lesser curvature of the stomach and anastomosing with the right gastric artery.

Question 5

Describe the pathway of the Splenic artery.

Answer 5

Arises inferior to the left gastric artery. Moves left towards the spleen, posterior to the stomach and along the superior margin of the pancreas. It is obtained within the splenorenal ligament and terminates into 5 tortuous branches.

Question 6

What are the branches of the Splenic Artery?

Answer 6

1. Spleen.
2. Left Gastroepiploic Artery.
3. Short Gastric Artery.
4. Pancreatic Branches.

Question 7

What does the Left Gastroepiploic artery (division of the splenic artery) supply?

Answer 7

Greater curvatures of the stomach.

Question 8

Which artery does the Left Gastroepiploic Anastomose?

Answer 8

Right Gastroepiploic Artery.

Question 9

What does the Short Gastric Arteries (branch of the splenic artery) supply?

Answer 9

Fundus of the stomach.

Question 10

What does the pancreatic branches of the splenic artery supply?

Answer 10

Body and tail of the pancreas.

Question 11

Describe the path of the Common Hepatic Artery.

Answer 11

Passes to the right, past the superior aspect of the duodenum where it divides into 2 branches: Proper hepatic and Gastroduodenal arteries.

Question 12

What are the 2 main branches of the common hepatic artery?

Answer 12

1. Proper Hepatic Artery.

2. Gastroduodenal Artery.

Question 13

Name the branches of the Proper Hepatic Artery.

Answer 13

1. Right Gastric Artery.
2. Right and Left Hepatic Artery.
3. Cystic Artery.

Question 14

What does the Right Gastric Artery (branch of the proper hepatic artery) supply?

Answer 14

Lesser curvature of the stomach.

Question 15

What does the Left and Right Hepatic Artery (branch of the proper hepatic artery) supply?

Answer 15

Supply respective lobes of the liver.

Question 16

What does the Cystic Artery (branch of the proper hepatic artery) supply?

Answer 16

Supply the gallbladder.

Question 17

Name the branches of the Gastroduodenal Artery (branch of the Proper Hepatic Artery).

Answer 17

1. Right Gastroepiploic Artery.

2. Superior Pancreaticoduodenal Artery.

Question 18

What does the Right Gastroepiploic Artery (branch of the Gastroduodenal branch) supply?

Answer 18

Greater curvature of the stomach, found in the greater omentum.

Question 19

What does the Superior Pancreaticoduodenal Artery (branch of Gastroduodenal artery) supply?

Answer 19

Head of pancreas (anterior and posterior).

Question 20

What is the blood supply to the stomach?

Answer 20

Supplied by all 3 branches of the coeliac trunk through a system of anastomoses along the greater (Gastroepiploic and right hepatic and left splenic) and lesser (gastric arteries) curvatures.

Question 21

What is the blood supply to the pancreas?

Answer 21

Pancreaticoduodenal Arcuade- a network of arteries that surround the head. Superior Pancreaticoduodenal Artery comes from the Gastroduodenal artery of the Proper Hepatic Artery and the Inferior comes from the Superior Mesenteric Artery.

Question 22

What is the difference in origins of the left and right Gastroepiploic arteries?

Answer 22

Left arises from the splenic artery and right arises from the common hepatic artery via the Gastroduodenal artery.

Question 23

What is the difference in origins of the Left and Right Gastric Arteries?

Answer 23

Left Gastric artery arises directly from the coeliac trunk and the right gastric artery arises from the common hepatic artery via the proper hepatic artery.
