What is the left colic artery?

The left colic artery supplies blood flow to the distal third of the transverse colon and the entirety of the descending colon. The descending branch moves inferiorly from the bifurcation to supply the distal descending colon—the descending branch anastomoses with the superior sigmoid artery.

Where does left colic artery come from?

The left colic artery is a branch of the inferior mesenteric artery, arising shortly after its origin from the aorta. It courses upwards posterior to the left colic mesentery and crosses over the anterior surface of the left psoas major muscle, left ureter and gonadal vessels.

What does the colic artery supply?

The middle colic artery is a branch of the superior mesenteric artery that mostly supplies the transverse colon. It arises just below the pancreas. It passes inferiorly and anteriorly between the layers of the transverse mesocolon, and divides into left and right branches.

What is IMA origin?

Anatomical terminology In human anatomy, the inferior mesenteric artery, often abbreviated as IMA, is the third main branch of the abdominal aorta and arises at the level of L3, supplying the large intestine from the distal transverse colon to the upper part of the anal canal.

What does left colic vein do?

The left colic vein drains the descending colon. It is a tributary of the inferior mesenteric vein, and follows the path of its corresponding artery, the left colic artery.

What does the left gastric artery supply?

The left gastric artery supplies blood to the lower curvature of the stomach along with its counterpart, the right gastric artery. The lower curvature of the stomach, also called the greater curvature, is the large, curving surface of the left side of the stomach.

Where is the left gastric artery?

The left gastric artery arises from the superior surface of the splenic artery distal to the division of the celiac trunk into the main hepatic and splenic arteries. The left gastric artery is distributed predominantly to the left lobe of the liver with lesser gastric supply.

What artery connects the middle colic artery to the left colic artery?

inferior mesenteric artery
The connection between the middle colic artery and the left colic artery is called the arc of Riolan. It is located approximately at the junction between the transverse and the descending colon and connects the domains of the superior and inferior mesenteric artery.

How long is the middle colic artery?

10 cm long
Its delivery area was typical for the middle colic artery. It was 10 cm long and gave four branches: right colic and three middle colic arteries (right, median and left). Their diameters were similar and measured about 2.5 mm. Anastomoses among them were well developed and their diameters ranged between 1.4 and 1.5 mm.

Where does left gastric vein come from?

The left gastric vein (or coronary vein) is a vein that derives from tributaries draining the lesser curvature of the stomach.
