vascular hemophilia

Not in common usage. See von Willebrand disease.

hemophilia

a condition characterized by impaired coagulability of the blood, and a strong tendency to bleed. See also deficiency of the following clotting factors, afibrinogenemia and hypoprothrombinemia, and proconvertin, stuart factor, plasma thromboplastin antecedent, hageman factor and fibrin stabilizing factor.

hemophilia A
classical hemophilia, due to deficiency of clotting factor VIII-C; occurs in dogs, horses and cats and is transmitted by the female to the male as a sex-linked recessive abnormality.
hemophilia B
a form similar to classical hemophilia but due to a deficiency of clotting factor IX; called also christmas disease and factor IX deficiency. Occurs in dogs and cats.
hemophilia C
in dogs an autosomal dominant form due to deficiency of clotting factor XI (plasma thromboplastin antecedent). Called also factor XI deficiency. The disease also occurs in cattle but the clinical disease is minor and it is inherited as a recessive character.
double hemophilia
dogs with both hemophilia A and hemophilia B have been produced experimentally.
vascular hemophilia
deficiency of clotting factor VIII and factor VIII-related antigen occurs in many breeds of dogs, particularly Doberman Pinschers, and in rabbits and pigs. See also von willebrand's disease.
