Spontaneous uterine rupture at a non-cesarean section scar site caused by placenta percreta in the early second trimester of gestation: A case report

Abstract

Objectives: Risk factors for placenta percreta are placenta previa and prior cesarean delivery. Placenta percreta–induced ruptures at non-cesarean sites are very rare, particularly in the early second trimester. Case report: A 30-year-old woman with a prior cesarean delivery was brought to our emergency department at 17 weeks' gestation for sudden-onset consciousness loss and generalized convulsions. Hypovolemic shock was identified. Computed tomography scans suggested uterine rupture and massive ascites, r/o hemoperitoneum. Emergency exploratory laparotomy revealed a ruptured hole over the left uterine fundus with protruding placental tissue; placenta percreta was impressed. An intact intrauterine sac was dissected and removed. The placenta was removed and hysterorrhaphy was completed. Conclusion: Placenta percreta is dangerous and is rarely seen in the early second trimester. Uterine rupture should always be kept in mind in pregnant woman with acute abdomen associated with hypovolemic shock, even in those of early pregnancy without scarred uterus. Routine sonographic examination of placentation, even in early second trimester, should be emphasized.
