Placental abruption (also known as abruptio placentae) is a complication of pregnancy, wherein the placental lining has separated from the uterus of the mother prior to delivery.
A placental abruption (abruptio placentae) is when a normally implanted placenta separates from the uterus after 20 weeks gestation (less then 20 weeks gestation is considered a spontaneous abortion). It occurs in approximately 0.5-1% of pregnancies in North America (Broers et al, 2004).he classical presentation is that a placental abruption is painful bleeding and a placenta previa is painless, however a woman with a placenta previa can also be contracting and thus can be in pain as well. A pelvic exam should not be done until a placenta previa can be ruled out as this can trigger further bleeding.
