Spontaneous rupture of an unscarred uterus in nongravid horn of bicornuate uterus

Abstract

Uterine rupture in pregnancy is rare and often catastrophic obstetric event with a high maternal and perinatal complication rate.1Numerous risk factors are known to increase the risk of rupture, but even in high risk groups, overall incidence of uterine rupture is low around 0.07 %.2 Rupture of unscarred uterus may be caused by trauma or congenital or acquired weakness of the myometrium. Contributing factors include exposure to uterotonic drugs, high parity, uterine anomalies, advancing maternal age, dystocia, marosomia, multiple gestation, abnormal placentation, short pregnancy interval. Most ruptures occur in women who had a previous transmyometrial incision, typically for cesarean delivery.Spontaneous rupture in an unscarred uterus is extremely rare. We present a case of spontaneous third trimester uterine rupture in unscarred uterus with Mullerian anomaly. This is extremely rare case of its own we encountered for the first time in our department.
