title: Spontaneous uterine laceration in labor: a type of intrapartum uterine injury different from the classical uterine rupture.
abstract: Uterine rupture, a complete disruption of uterine wall, is synonymously used of intrapartum uterine corpus injuries. However, uterine laceration, partial and minor myometrial tear, is not well characterized. A 35-year-old Japanese woman with unscarred uterus was delivered of a baby at 38 gestational weeks. Shortly after delivering the placenta, she complained of severe lower abdominal pain with shock vitals. Exploratory laparotomy revealed a partial and shallow myometrial and serosal tear with massive hemoperitoneum. Despite its shallow and minor nature of the injury, uterine laceration can cause a catastrophic massive hemoperitoneum and should be noted as a type of intrapartum uterine injury in clinical practice.
