Couvelaire uterus.

Uteroplacental apoplexy is a rare but nonfatal complication of severe forms of placental abruption. It occurs when vascular damage within the placenta causes hemorrhaging that progresses to and infiltrates the wall of the uterus. It is a syndrome that can only be diagnosed by direct visualization or biopsy (or both). For this reason, its occurrence is perhaps underreported and underestimated in the literature. The subject of this report is a 24-year-old pregnant woman who had a placental abruption an in whom classic uteroplacental apoplexy was diagnosed at the time of her cesarean section.
