The sigmoid arteries are 2–5 branches of the inferior mesenteric artery that are distributed to the distal descending colon and the sigmoid colon.
Anatomy
Course and relations
The sigmoid arteries course obliquely inferior-ward and to the left, passing posterior to the
peritoneum and in anterior to the
psoas major,
ureter,
and
Gonadal artery.
Anastomoses
The sigmoid arteries anastomose with the
left colic superiorly, and with the superior rectal artery inferiorly.
