Bleeding Disorder in Cats

Treatment

Transfusion of fresh whole blood, fresh plasma, fresh frozen plasma, and cryoprecipitate will supply vWF to the blood. Component therapy (fresh frozen plasma or cryoprecipitate) is best for surgical prophylaxis (prevention) and nonanemic patients, to prevent red cell sensitization and volume overload. Patients with severe vWD may require repeated transfusion to control or prevent hemorrhage. If a cat lacking vWF requires surgery, a pre-operative transfusion should be given just before the procedure.

Living and Management

Most cats with mild to moderate vWD will continue to have a good quality of life, requiring minimal or no special treatment. Cats with more severe forms will require transfusion for surgery, and should be transfused if supportive care fails to control a spontaneous bleeding episode. Most of these cats can be maintained comfortably, but their activities will need to be monitored and limited. If your cat has von Willebrand Disease and it has an episode of prolonged bleeding, call your veterinarian and take it to a veterinary clinic immediately for emergency treatment.
