Placental abruption (abruptio placentae) is not a common complication of pregnancy, but it is a serious condition.
The placenta develops in the uterus during pregnancy. It appends to the walls of the uterus and supplies the fetus with nutrients and oxygen. Placental abruption happens when the placenta, in part or totally, separates from the walls of the uterus before delivery. This can diminish or obstruct the baby’s supply of oxygen and nutrients and can cause substantial bleeding in the mother.
Placental abruption frequently happens suddenly. Left untreated, it is dangerous to both the mother and the baby.
