Spontaneous uterine rupture caused by placenta percreta

Uterine body placenta accreta spectrum: A detailed literature review

Placenta accreta spectrum (PAS) is a major obstetrical problem whose incidence is rising. Current guidelines recommend screening of all women with placenta previa and risk factors for PAS between 20 and 24 weeks. Risk factors, diagnosis, and management of previa PAS are well established, but an apparently normal location of the placenta does not exclude PAS. Literature data are scarce on uterine body PAS, which carries a high risk of maternal and neonatal adverse outcome, but is still easily missed on prenatal ultrasound. We conducted a comprehensive review to identify possible risk factors, clinical presentations, and diagnostic modalities of uterine PAS. A total of 133 cases were found during a 70-year period (1949-2019). The vast majority of them presented with signs of uterine rupture, even prior to the viability threshold of 24 weeks (up to 45%). Major risk factors included previous cesarean delivery, uterine curettage, uterine surgery, Asherman's syndrome, manual removal of the placenta, endometritis, high parity, young maternal age, in vitro fertilization, radiotherapy, uterine artery embolization, and uterine leiomyoma. Diagnosis was pre-symptomatic in only 3% of cases. Future studies should differentiate between previa PAS and uterine body PAS.

Placenta percreta--two cases and review of the literature

Two cases of placenta pecreta confirmed histologically were treated conservatively with retention of the uterus. Both later went on to have successful pregnancies.

An unusual cause of abdominal pain and shock in pregnancy: case report and review of the literature

A near fatal case of spontaneous uterine rupture resulting from placenta percreta is presented. Placenta accreta refers to all conditions in which placental villi attach to, invade, or penetrate the myometrium. Placenta percreta is the most extreme form of morbid placental attachment and is said to exist when the uterine wall is completely breached by invading placental villi. Although uncommon, placenta percreta is an important entity of which the emergency physician should be aware because of its propensity to cause uterine rupture and catastrophic bleeding. This article reviews the pathophysiology, presentation, diagnosis, and emergency department management of placenta accreta, increta, and percreta.
