The middle rectal artery is an artery in the pelvis that supplies blood to the rectum.
Structure
[edit | edit source]
The middle rectal artery usually arises from the internal iliac artery.[1] It is distributed to the rectum above the pectinate line.[2] It anastomoses with the inferior vesical artery, superior rectal artery, and inferior rectal artery.[2]
In males, the middle rectal artery may give off branches to the prostate and the seminal vesicles. In females, the middle rectal artery gives off branches to the vagina.
Function
[edit | edit source]The middle rectal artery supplies the rectum[2] and the anal canal inferior to the pectinate line. [3][4]
Pathology
[edit | edit source]The middle rectal artery may be embolized to treat patients with symptomatic internal hemorrhoids in a procedure called hemorrhoidal artery embolization.[5]
