Spontaneous rupture of an unscarred uterus at the early third trimester due to placenta percreta: a case report

Uterine rupture during pregnancy is a complication of placenta percreta. We present the case of a woman in her early 30s with a history of incomplete abortion treated by dilatation and curettage who was admitted with abdominal pain and vomiting at 30 weeks of gestation. She was diagnosed with thrombophilia and was administered anticoagulant drugs. After 10 hours of monitoring, the patient abruptly deteriorated. An emergency cesarean delivery showed a ruptured uterus due to placenta percreta. She accepted localized excision and uterine repair, and recovered well. Rupture of an unscarred uterus due to placental percreta is an extremely rare obstetric complication with high maternal and fetal mortality. This condition should be suspected in all pregnant women who have severe abdominal pain without being in labor. The treatment of uterine rupture due to placental percreta should be individualized, and repair of the uterus is possible in the majority of women.
