What is superior rectal artery?

The superior rectal artery is a branch of the inferior mesenteric artery, which arises from the abdominal aorta. It supplies blood to the upper part of the rectum, as well as the sigmoid colon.

The superior rectal artery runs along the posterior wall of the pelvis, giving off branches that provide blood to the rectum and surrounding structures. It anastomoses with the middle and inferior rectal arteries, which also supply blood to the rectum.

In terms of clinical significance, the superior rectal artery can be involved in conditions such as hemorrhoids, rectal cancer, and rectal prolapse. Surgical procedures involving the rectum may also require careful consideration of the superior rectal artery to avoid complications related to blood supply.

Overall, the superior rectal artery plays an important role in ensuring proper blood supply to the rectum and is an essential component of the larger mesenteric vascular system.
