<unk>  is a phenomenon where the retroplacental blood may penetrate through the thickness of the wall of the uterus into the peritoneal cavity. This may occur after abruptio placentae. The hemorrhage that gets into the decidua basalis ultimately splits the decidua, and the haematoma may remain within the decidua or may extravasate into the myometrium (the muscular wall of the uterus). The myometrium becomes weakened and may rupture due to the increase in intrauterine pressure associated with uterine contractions. This may lead to a life-threatening obstetric emergency requiring urgent delivery of the fetus.
