Outer Profile of the Diverse Uterine Veins

Description

Running along the lateral borders of the uterus, the uterine venous plexus spreads within the broad ligament and tracks toward the pelvic sidewall. Multiple uterine veins emerge from this plexus near the cervix and uterine body, accompanying the uterine artery in the cardinal (transverse cervical) ligament and then draining into the internal iliac venous system. Superficially, smaller tributaries from the fundus and cornual region communicate with the ovarian veins within the suspensory ligament of the ovary, creating a continuous pathway between uterine, tubal, and ovarian drainage. Venous channels lie close to the myometrium and sit medial to the ureter as the ureter courses inferiorly toward the bladder. Tight quarters. This outer profile matters because uterine veins do not behave like a single named trunk, they form a low pressure, valveless plexiform network that can bleed briskly when torn or avulsed. During hysterectomy (abdominal, laparoscopic, or vaginal), secure control of the uterine pedicle depends on recognizing how the venous plexus wraps the cervix and lower uterine segment while the ureter passes just inferior to the uterine artery at the level of the cervix. The same venous interconnections explain common routes of pelvic congestion syndrome and help contextualize postpartum hemorrhage when broad ligament or parametrial hematomas track laterally. Use this plate for teaching pelvic vasculature in gross anatomy and OB-GYN modules, for surgical atlases illustrating uterine pedicle ligation and ureteric injury avoidance, and for patient education materials explaining pelvic varicosities and chronic pelvic pain.
