A rare, inherited blood disorder in which the blood does not clot normally. It can occur in both sexes.
Treatment is only necessary if there is severe bleeding or in preparation for surgery.
Individuals with this condition should be immunized with the hepatitis B vaccine because of the increased risk of developing hepatitis due to transfusion of blood products. The prognosis is good when patients seek proper treatment. Call your health care provider or seek emergency care if excessive bleeding occurs. Notify your surgeon before you have surgery if you know or suspect you have a blood disorder. The information provided herein should not be used for diagnosis or treatment of any medical condition.
