Complete Inventory of Uterine Veins

Description

Arising within the endometrium, coiled spiral venules converge into a subendometrial venous plexus that drains outward through the myometrium toward larger uterine veins along the lateral uterine wall. Venous channels course within the stratum vasculare, running between bundles of myometrial smooth muscle, then collect near the uterine cornu and cervix before entering the broad ligament. Laterally, the uterine veins track in close company with the uterine artery, and they communicate with vaginal venous plexuses inferiorly and with ovarian venous pathways superiorly near the uterine tube and ovary. Venous anatomy here matters because uterine bleeding and pelvic venous congestion are often discussed in arterial terms, yet surgical hemostasis, postoperative hematoma, and parametrial bleeding frequently involve thin-walled venous plexuses that retract poorly. During hysterectomy or uterine-sparing procedures, the relationship of the uterine veins to the ureter at the level of the cervix and uterine artery crossing is a recurring hazard, and venous back-bleeding from the uterine and vaginal plexuses can obscure this landmark fast. In obstetrics, postpartum hemorrhage and retained products can be better understood when you keep the spiral venules and their myometrial drainage pathways in mind. Small vessels, big consequences. Use this plate in reproductive anatomy and histology teaching to connect endometrial spiral vasculature with uterine wall layers, and in gynecologic surgery texts to support sections on hysterectomy, uterine artery ligation, and parametrial dissection. It also fits pelvic vascular modules addressing venous plexuses, pelvic congestion syndrome, and sources of intraoperative bleeding in the female pelvis.
