Answer 1

• Left Gastric Artery
• Common Hepatic Artery

  • Gastroduodenal
  • Hepatic proper (gives right and left hepatic)
  • Cystic (occasionally)
• Splenic Artery
  
  • Pancreatic
  • Short Gastric
  • Left Gastroepiploic

Question 2

What is the blood supply of the Spleen?

Answer 2

Splenic artery branch of Celiac Trunk

Question 3

What is the blood supply of the Stomach?

Answer 3

• Right gastric– branch of the proper hepatic artery, which arises from the common hepatic artery.
• Left gastric– arises directly from the coeliac trunk.
• Right gastro-omental– terminal branch of the gastroduodenal artery, which arises from the common hepatic artery.
• Left gastro-omental– branch of the splenic artery, which arises from the coeliac trunk.

Question 4

What is the blood supply of the Pancreas?

Answer 4

• Celiac trunk → Common hepatic artery → Gastroduodenal artery → superior pancreaticoduodenal artery
• SMA → inferior pancreaticoduodenal artery
• Celiac trunk → Splenic artery → Pancreatic branches

Question 5

What is the blood supply of the appendix?

Answer 5

• Appendicular artery from the ileocolic artery
• Appendicular vein to SMV

Question 6

What is the blood supply of the Duodenum?

Answer 6

• Proximal to Major duodenal papilla: Celiac trunk → Common hepatic artery → Gastroduodenal artery + superior pancreaticoduodenal artery
• Distal to Major duodenal papilla: SMA → inferior pancreaticoduodenal artery

Question 6

What are the branches of the SMA?

Answer 6

1. Inferior pancreaticoduodenal artery
2. Jejunal and Ileal Arteries
3. Middle colic artery: supplies the transverse colon.
4. Right colic artery: supplies the ascending colon.
5. Ileocolic Artery: supplies the ascending colon, appendix, cecum, and ileum. In cases of appendectomy, the appendicular artery is ligated.

Question 7

What are the branches of the IMA?

Answer 7

1. Left colic artery: supplies distal 1/3 of the transverse colon and the descending colon.
2. Sigmoid artery: supplies the descending colon and the sigmoid colon.
