Can inferior mesenteric artery be ligated?

Can inferior mesenteric artery be ligated?

During surgery for colorectal cancer, the inferior mesenteric artery (IMA) may be ligated either directly at the origin of the IMA from the aorta (high ligation) or at a point just below the origin of the left colic artery (low ligation).

Where does the inferior mesenteric vein terminate?

splenic vein
In human anatomy, the inferior mesenteric vein (IMV) is a blood vessel that drains blood from the large intestine. It usually terminates when reaching the splenic vein, which goes on to form the portal vein with the superior mesenteric vein (SMV).

Which of the following vein is joining the inferior mesenteric vein?

The inferior mesenteric vein (IMV) drains the descending colon, the sigmoid colon, and the rectum through the left colic vein, the sigmoid branches, and the superior rectal vein, respectively. The IMV joins the splenic vein, which then joins the SMV to form the portal vein.

Which vein receives blood from inferior mesenteric?

Spleen Anatomy and Histology The gastrosplenic ligament carries the short gastric and left gastroepiploic vessels to the stomach and spleen. The splenic vein receives the inferior mesenteric vein and joins the superior mesenteric vein behind the neck of the pancreas to form the portal vein.

What does the inferior mesenteric artery supply?

The branches of the inferior mesenteric artery include 1) the left colic, which is located retroperitoneally and supplies the descending colon; 2) the sigmoid branches, which supply the sigmoid colon; and 3) the superior rectal artery, which is the terminal branch of the inferior mesenteric artery at the pelvic brim.

What are the branches of the inferior mesenteric artery?

There are three major branches that arise from the IMA – the left colic artery, sigmoid artery and superior rectal artery. The left colic artery is the first branch of the IMA.

How do you identify an inferior mesenteric vein?

Venous Anatomy The inferior mesenteric vein usually enters the splenic adjacent to the confluence, but it may also enter the SMV either at or just caudal to the confluence. The coronary vein most often drains into the cephalic aspect of the main portal vein just beyond the confluence of the SMV and splenic vein.

What is mesenteric vein thrombosis?

Mesenteric venous thrombosis (MVT) is a blood clot in one or more of the major veins that drain blood from the intestine. The superior mesenteric vein is most commonly involved.

What level is the inferior mesenteric artery?

L2-L4
The inferior mesenteric artery (IMA) is another major blood supply to the lower GI tract (Fig. 25.4). It is located at the level of L2-L4 (most often at the L3-L4 disk space level, 2–3 cm above the aortic bifurcation). The IMA supplies the distal transverse colon, descending colon, sigmoid colon, and rectum.

Which artery is a branch of the inferior mesenteric artery?

superior rectal artery
The superior rectal artery is the terminal branch of the Inferior mesenteric artery, providing blood flow to the rectum. It descends into the pelvis coursing anteriorly to the left common iliac artery and vein. The superior rectal artery bifurcates into terminal branches around the S3 vertebral level.

What is the origin of the inferior mesenteric artery?

The inferior mesenteric artery arises from the abdominal aorta at the level of the third lumbar vertebra. It supplies the hindgut and has four major branches called left colic, sigmoid and superior rectal arteries.
