Superior hemorrhoidal artery

Superior Hemorrhoidal Artery

The superior hemorrhoidal artery is a branch of the inferior mesenteric artery.

The Superior Hemorrhoidal Artery is an artery that supplies blood to the rectum and anus. It is the continuation of the Inferior Mesenteric Artery after it crosses the left common iliac artery.

Structure

The Superior Hemorrhoidal Artery descends into the pelvis, dividing into two branches. These branches descend into the pelvis, supplying the upper part of the rectum. They further divide into smaller branches that reach the lower part of the rectum and the upper part of the anus.

Function

The primary function of the Superior Hemorrhoidal Artery is to supply blood to the upper part of the rectum and the upper part of the anus. This is crucial for the functioning of the digestive system, as these areas are involved in the final stages of digestion and the expulsion of waste from the body.

Clinical significance

Knowledge of the Superior Hemorrhoidal Artery is important in surgical procedures involving the rectum and anus, such as hemorrhoidectomy and colorectal surgery. Damage to this artery during surgery can lead to significant bleeding and other complications.
