Concealed Uterine Rupture in the Broad Ligament in an Unscarred Uterus With Postpartum Hemorrhage

Uterine rupture is an obstetric emergency that traditionally occurs during delivery in a mother with previously known risk factors, especially a uterine scar. However, a rupture that occurs in an unscarred uterus is uncommon. We report a case of a low-risk mother who presented for induction of labor for late-term pregnancy, without a history of uterine surgery, required vacuum-assisted vaginal delivery for maternal exhaustion, and one hour later was noted to have postpartum hemorrhage. The postpartum hemorrhage was managed medically but was taken for curettage due to continued hemorrhage and hemodynamic instability, followed by laparotomy which identified an 11 cm vertical uterine rupture parallel to the ascending uterine artery concealed in the broad ligament and extending inferiorly to the lateral cervix, necessitating a total abdominal hysterectomy. The patient tolerated the procedures well and was discharged home on postoperative day 2. Highlighting the importance of a high index of suspicion for uterine rupture, even without risk factors, this report describes an atypical presentation and describes an effective stepwise approach to management.
