Von Willebrand disease is the most common hereditary bleeding disorder.
Bleeding disorder - von Willebrand
Von Willebrand disease is caused by a deficiency or poor functioning of von Willebrand factor. Von Willebrand factor helps blood platelets clump together and stick to the blood vessel wall, which is necessary for normal blood clotting. There are several types of von Willebrand disease.
A family history of a bleeding disorder is the primary risk factor.
Symptoms may include:
Note: Most women with heavy or prolonged menstrual bleeding do not have von Willebrand disease.
Treatment may include DDAVP (desamino-8-arginine vasopressin). It is a medicine to raise von Willebrand factor level and reduce the chances for bleeding.
However, DDAVP does not work for all types of von Willebrand disease. Tests should be done to determine what type of von Willebrand you have. If you are going to have surgery, your doctor may give you DDAVP before surgery to see if your von Willebrand factor levels increase.
The drug Alphanate (antihemophilic factor) is approved to decrease bleeding in people with the disease who must have surgery or any other invasive procedure.
Blood plasma or certain factor VIII preparations may also be used to decrease bleeding.
Bleeding may decrease during pregnancy. Women who have this condition usually do not have excessive bleeding during childbirth.
This disease is passed down through families. Genetic counseling may help prospective parents understand the risk for their children.
Bleeding may occur after surgery or when you have a tooth pulled.
Aspirin and other nonsteroidal anti-inflammatory drugs (NSAIDs) can make this condition worse. Do not take these medicines without first talking to your health care provider.
Contact your provider if bleeding occurs without reason.
If you have von Willebrand disease and are scheduled for surgery or are in an accident, be sure you or your family tell the providers about your condition.
