Antepartum Rupture of the Posterior Uterine Wall in a Woman With Two Previous Cesarean Deliveries.

Uterine rupture is a rare pregnancy complication. In patients with a previous cesarean delivery, it usually involves the scarred area. Uterine rupture of the posterior wall is even rarer and mostly described during labor. Conditions that confer fragility to the posterior uterine wall have been associated with an increased risk of uterine rupture. There are very few cases of spontaneous posterior uterine wall rupture in a non-labor setting in pregnant women without risk factors. We report the case of a pregnant woman admitted to the hospital due to placental abruption at 26 weeks' gestation. Once fetal and maternal stability were assured, expectant management was maintained. At 29 weeks, an emergent cesarean delivery due to fetal bradycardia was performed, and a large rupture of the posterior uterine wall was diagnosed. Subsequently, a hysterectomy was performed. The patient was discharged nine days after the procedure and the newborn on the 64th day of life.
