Couvelaire uterus (also known as uteroplacental apoplexy) [1] is a rare but not a life-threatening condition in which loosening of the placenta (abruptio placentae) causes bleeding that penetrates into the uterine myometrium forcing its way into the peritoneal cavity. This condition makes the uterus very tense and rigid.
Causes of increased foetal-maternal haemorrhage are seen as a result of trauma, placental abruption or may be spontaneous with no cause found. Up to 30ml of foetal-maternal transfusion may take place with no significant signs or symptoms seen in either mother or foetus. [3]
Risk factors such as diabetes, chronic blood pressure and multiple pregnancies can increase the risk of developing placental disease. [3] Also, exposure to sudden trauma can increase the risk of placental abruption which coincides with placental disease. [6] There is no target treatment available for placental disease.
Placental abruption causes blood loss from the mother and loss of oxygen and nutrients to the placenta occasionally leading to preterm labour. [14] Other causes of placental abruption can be abdominal trauma or sudden decompression of amniotic fluid , however it is not uncommon for the cause of placental abruption to be unknown.

Symptoms may include abdominal pain or vaginal bleeding during pregnancy. [1] As this is nonspecific in areas where ultrasound is not available the diagnosis was often only discovered during surgery to investigate the abnormal symptoms.
