Ligament
Broad ligament
A peritoneal fold organizing the uterine adnexa
High-yield
Mesometrium relates to the uterus, mesosalpinx to the tube and mesovarium to the ovary. The ureter lies in underlying extraperitoneal tissue near the ligament's base.
Overview
The broad ligament is a double layer of peritoneum extending from the uterus toward the pelvic sidewalls. Its named portions relate to the uterus, tube and ovary. It organizes these relationships, while the deeper connective tissue supports of the cervix and vagina provide much of the resistance to prolapse.
Reference facts
- Attachments
- Extends laterally from the uterus to the pelvic wall; its superior part surrounds the tube, and the mesovarium attaches to its posterior aspect.
- Function
- Organizes the adnexa and provides peritoneal coverings around pathways for vessels and other structures. Major apical support also depends on cardinal–uterosacral connective tissue and the pelvic floor.
- Clinical point
- Paratubal cysts and masses may occur within or near its layers; enlarging lesions can distort the adjacent ureter and vascular pedicles.
Clinical correlation
Masses growing between the peritoneal layers can displace vessels and the ureter. The uterine artery–ureter relationship is in the connective tissue near the base; the cardinal ligament is a deeper support, not simply thickened peritoneum.
Frequently asked questions
