Arteries to learn

Superior mesenteric artery branches

It arises from the abdominal aorta, and supplies arterial blood to the organs of the midgut 

• from the major duodenal papilla (of the duodenum) to the proximal 2/3 of the transverse colon. (Starts from L1)

Inferior Pancreaticoduodenal Artery
Supplies the inferior region of the head of the pancreas, the uncinate process, and the duodenum.

Jejunal and Ileal Arteries
The superior mesenteric artery gives rise to numerous arteries that supply the jejunum and ileum.

Middle and Right Colic Arteries
Middle colic artery –  supplies the transverse colon.

Right colic artery – supplies the ascending colon.

Ileocolic Artery

branches to the ascending colon, appendix, cecum, and ileum.

Inferior mesenteric artery branches

Supplies arterial blood to the organs of the hindgut – the distal 1/3 of the transverse colon, splenic flexure, descending colon, sigmoid colon and rectum

• arises at the L3 vertebral level,

• Retroperitoneal

Left Colic Artery
Supplies the distal 1/3 of the transverse colon and the descending colon.

Sigmoid Arteries
The sigmoid arteries supply the descending colon and the sigmoid colon.

Superior Rectal Artery
The superior rectal artery is a continuation of the inferior mesenteric artery, supplying the rectum

Describe the anastomose between sma and ima

Marginal artery

Straight vessels (vasa recta) arise from the artery to supply the colon

formed by the union of several branches; the ileocolic, right colic and middle colic of the SMA and left colic and sigmoid branches of the IMA.

Describe the coeliac trunk

It arises from the anterior aspect of the aorta at the aortic hiatus of the diaphragm (T12 level).

Left Gastric Artery
giving rise to oesophageal branches, before continuing anteriorly along the lesser curvature of the stomach. Here, it anastomoses with the right gastric artery.

Splenic Artery
travels left towards the spleen, running posterior to the stomach and along the superior margin of the pancreas.

Common Hepatic Artery
The common hepatic artery is the sole arterial supply to the liverdivides into its two terminal branches – the proper hepatic and gastroduodenal arteries.

Describe Splenic Artery branches

• Left gastroepiploic(gastroomental): supplies the greater curvature of the stomach. Anastomoses with the right gastroepiploic artery.

• Short gastrics: 5-7 small branches supplying the fundus of the stomach.

• Pancreatic branches: supply the body and tail of the pancreas.

Describe proper hepatic artery branches

Proper Hepatic

The proper hepatic artery ascends through the lesser omentum towards the liver. It gives rise to:

• Right gastric: supplies the pylorus and lesser curvature of the stomach.

• Right and left hepatic: divide inferior to the porta hepatis and supply their respective lobes of the liver.

• Cystic: branch of the right hepatic artery – supplies the gall bladder

Describe gastroduodenal artery branches

Gastroduodenal

The gastroduodenal artery descends posterior to the superior portion of the duodenum. Its branches are:

• Right gastroepiploic: supplies the greater curvature of the stomach. Found between the layers of the greater omentum, which it also supplies.

• Superior pancreaticoduodenal: divides into an anterior and posterior branch, which supplies the head of the pancreas.

Describe the anastomose of the pancreaticoduodenal arteries

• Superior pancreaticoduodenal– a branch of the gastroduodenal artery.

• Inferior pancreaticoduodenal – branch of superior mesenteric artery (SMA).
