Other factors of an abruption include trauma and abnormalities of the uterus or umbilical cord, and being over 35 years of age.

The main sign of placental abruption is dark red vaginal bleeding. This bleeding may be slight or it may be quite profuse.Various factors may increase the risk of placental abruption. High blood pressure increases the risk of placental abruption, whether you have chronic high blood pressure or the high blood pressure first developed during pregnancy. Placental abruption is more common in women age 40 and older. Placental abruption is more common in women who smoke, drink alcohol, or use cocaine or methamphetamine during pregnancy. The risk of placental abruption is higher if you have an unusually large amount of amniotic fluid.
