Artery: Sigmoid arteries

Sigmoid colon and rectum, showing distribution of branches of inferior mesenteric artery and their anastomoses

The inferior mesenteric artery and its branches (sigmoid arteries labeled at bottom right)
Latin	Arteriae sigmoideae
Gray's	p.610

The sigmoid arteries, two or three in number, run obliquely downward and to the left behind the peritoneum and in front of the Psoas major, ureter, and internal spermatic vessels.

Their branches supply the lower part of the descending colon, the iliac colon, and the sigmoid or pelvic colon; anastomosing above with the left colic, and below with the superior hemorrhoidal artery.
