The sigmoid arteries/branches are a set of 2-4 arteries that branch directly off of the IMA.
Aorta → IMA → Sigmoid Branches
The superior branch anastomoses with the left colic artery while the inferior branch anastomoses with the superior rectal artery.
These arteries perfuse the sigmoid colon with oxygenated blood.
