The broad ligament is a sheet-like fold of peritoneum, oriented in the coronal plane that runs from the lateral pelvic wall to the uterus, and encloses the uterine tube in its superior margin and suspends the ovary from its posterior aspect (Fig. 5.59A). The uterine arteries cross the ureters at the base of the broad ligaments, and the ligament of the ovary and round ligament of the uterus are enclosed within the parts of the broad ligament related to the ovary and uterus, respectively. The broad ligament has three parts: the mesometrium, the largest part of the broad ligament, which extends from the lateral pelvic walls to the body of the uterus; the mesosalpinx, the most superior part of the broad ligament, which suspends the uterine tube in the pelvic cavity; and the mesovarium, a posterior extension of the broad ligament, which attaches to the ovary.
