Angiohemophilia, also known as von Willebrand disease, refers to a hereditary blood disease by the principle of autosomal domination. Its main symptom is similar to that of hemophilia, incidental spontaneous bleedings.
In 1926, the scientist Erik von Willebrand first studied the disease when he tried to describe a family with group of hemorrhagic disorders from the Aland Islands. Angiohemophilia is different from hemophilia. Symptoms of angiohemophilia vary, depending on the severity and type of the disease, including prolonged bleeding time and impaired platelet adhesion. Families with angiohemophilia are likely to have the same expressiveness of deficiency of factor VIII.
