prothrombin deficiency


A congenital or acquired disorder of blood clotting where there is a deficiency of factor II (prothrombin), one of 20 necessary plasma proteins for normal blood coagulation. Acquired factor II deficiency may result from vitamin K deficiency, severe liver disease and anticoagulant drugs.

Symptoms include abnormal bleeding, nosebleeds, abnormal menstrual bleeding, easy bruising and umbilical cord bleeding at birth. Treatment involves the infusion of fresh frozen plasma. Vitamin K may be administered in select cases.
