Where does the left colic artery supply?
The left colic artery supplies blood flow to the distal third of the transverse colon and the entirety of the descending colon.
What artery supplies the left colic flexure?
The branches of the left colic artery anastomose with branches of the middle colic and sigmoid arteries and contribute to the formation of the marginal artery of Drummond, an arterial channel that supplies the large intestine….Left colic artery.

What do the colic arteries supply?
They supply the terminal portion of the ileum, the vermiform appendix, the colon ascendens, and part of the transverse colon. It is noteworthy that the right colic artery is missing in approximately 10% of individuals and that an accessory middle colic artery is present in approximately 10–20%.
What artery supplies the distal colon?
The right colic artery supplies blood to the mid-distal ascending colon. In anatomical studies, the right colic artery arises independently from the SMA in 28% of individuals, which is depicted in this figure.
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 gives off esophageal branches and supplies the upper right portions of the fundus and body of the stomach, as well as the distal (abdominal) esophagus.
What is a left colic flexure?
Left colic flexure (or splenic flexure) is the bend in the large intestine in the left upper quadrant of the abdomen as the transverse colon continues as the descending colon. The phrenicocolic ligament attaches the splenic flexure to the left hemidiaphragm. It lies more cranial than the right colic flexure.
What does splenic flexure pain feel like?
Symptoms. The symptoms of splenic flexure syndrome include bloating, pain in the upper left abdomen, and a feeling of fullness in the abdomen. Causes. People with irritable bowel syndrome, or IBS, are most likely to have splenic flexure syndrome, with some experts even considering it to be a type of IBS.
What size is the middle colic artery?
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 is celiac trunk?
The celiac trunk, also known as the celiac artery, is a short vessel that arises from the aorta and passes below the median arcuate ligament, just as the aorta enters the abdomen at the level of the T12 vertebra. The celiac trunk measures about 1.5cm to 2cm in length.
What artery supplies the large intestine?
The blood supply to the large intestine originates in the superior and inferior mesenteric arteries.
What is colic flexure?
Left colic flexure (or splenic flexure) is the bend in the large intestine in the left upper quadrant of the abdomen as the transverse colon continues as the descending colon. The phrenicocolic ligament attaches the splenic flexure to the left hemidiaphragm.
What does the left colic artery supply?
Left colic artery (Arteria colica sinistra) The left colic artery is a branch of the inferior mesenteric artery that supplies the distal thirds of the transverse colon. It courses retroperitoneally behind the left colic mesentery until it bifurcates into an ascending and descending branch.
What does the ileocolic artery supply?
The right colic artery supplies the ascending colon above the cecum to the right colic flexure. The ileocolic artery also arises from the right side of the superior mesenteric artery and travels towards the right iliac fossa. It gives a superior (colic) and an inferior (ileal) branch.
Does the inferior mesenteric artery supply the left colon?
All branches of the inferior mesenteric artery have multiple divisions of fine arcades that supply the left colon in segments. The inferior mesenteric vein accompanies the inferior mesenteric artery.
What is the arterial supply to the colon?
Arterial Supply. The remainder of the colon – from the distal transverse colon to the rectosigmoid junction – receive arterial supply from the inferior mesenteric artery. It arises from the left anterior part of the abdominal aorta, about 4 cm superior to the aortic bifurcation and facing the L3 vertebra.
