The Complete Uterine Vasculature

Description

Arcuate uterine arteries course circumferentially within the myometrium, giving off radial arteries that run from the lateral uterine wall toward the endometrium, where they continue as straight and spiral arteries supplying the basalis and functionalis. Along the superolateral uterus, tubal and ovarian branches approach the uterine fundus, meeting uterine branches near the uterotubal junction in a dense anastomotic network. Inferiorly, cervical and vaginal branches contribute to the lower uterine segment and cervix, with the vascular channels arranged in layered fashion from serosa inward. Lateral uterine walls dominate the inflow territory. These relationships matter in the operating room. Uterine artery ligation for postpartum hemorrhage, hysterectomy, and myomectomy all depend on recognizing how robust arcuate and fundal anastomoses can preserve perfusion or, if missed, continue bleeding from collateral flow via ovarian or vaginal sources; the ureter’s close course beneath the uterine artery near the cervix drives the classic surgical hazard. In obstetrics, the spiral artery bed is the substrate for abnormal placentation and impaired trophoblastic remodeling, linking vascular anatomy to placenta accreta spectrum and preeclampsia. Use this artwork in reproductive anatomy and embryology teaching when you need a clear map of uterine blood supply from serosal arcade to endometrial microcirculation, or in OB-GYN texts covering hysterectomy steps, uterine-sparing hemorrhage control, and placental disorders. It also fits clinical lecture slides on uterine artery embolization and expected collateral pathways. Anatomical accuracy verified by SciePro's Medical Advisory Board.
