The superior rectal artery is an artery that supplies blood to the rectum down to the level of the levator ani 2.
Summary
- origin: the terminal branch of the inferior mesenteric artery is the superior rectal artery
- course: descends into the pelvic cavity in the sigmoid mesocolon, crossing the left common iliac vessels
-
branches:
- recto-sigmoid branch
- upper rectal branch
- right and left terminal branches: at the level of S3, these descend on each side of the rectum, dividing into smaller branches in the wall of the rectum
-
anastomoses
- middle rectal artery (branch of internal iliac artery)
- inferior rectal artery (branch of internal pudendal artery)
