What is the right colic artery?
The right colic artery is a branch of the superior mesenteric artery that supplies the ascending colon. It courses to the right towards ascending colon, where it splits into a superior and inferior division.
What is the colic artery?
Anatomical terminology. 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.
Does everyone have a right colic artery?
We have shown the right colic feeding vessel origin to be highly variable, arising from the SMA, ILC, MCA root and RBMC in a decreasing order of frequency. It is absent in 8.9% of cases, and two RCAs may be found in 7.0% of individuals.
Which branch of the abdominal aorta supplies the right colic area?
superior mesenteric artery
The superior mesenteric artery then gives off several jejunal and ileal arteries to the left, and the middle colic, right colic, and ileocolic arteries to the right.
Where does right colic artery come from?
The right colic artery may arise directly from the superior mesenteric artery (SMA) but often arises from a common trunk with the ileocolic artery or middle colic artery.
Is the right colic artery retroperitoneal?
The right colic artery (Latin: arteria colica dextra) is an inconsistent branch that arises from the right side of the superior mesenteric artery. The right colic artery passes to the right in a retroperitoneal position and supplies the ascending colon.
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.
How do you know if you have a middle colic artery?
Conventional methods to identify the middle colic artery include dissection of the superior mesenteric vein superiorly from the ileocolic vein (which risks middle colic vein injury, particularly in patients with enlarged vascular root lymph nodes) and rotation of the transverse colon and mesentery (which is less …
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.
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.
Where does right gastric artery come from?
The right gastric artery arises from the proper hepatic artery. The left gastroepiploic artery is a branch of the splenic artery. The gastroduodenal artery gives off the right gastroepiploic artery. All of this makes up the vascular circle of the stomach.
