Middle rectal veins
Editor-In-Chief: C. Michael Gibson, M.S., M.D. [1]
The middle rectal veins (or middle hemorrhoidal vein) take origin in the hemorrhoidal plexus and receive tributaries from the bladder, prostate, and seminal vesicle.
They run lateralward on the pelvic surface of the Levator ani to end in the hypogastric vein.
