Thromboxane responsiveness of platelets
Also known as: Thromboxane A2 receptor defect · Thromboxan-Rezeptor-Defekt · Platelet thromboxane responsiveness defect · Thrombozytopathie (Thromboxan-Rezeptor) · Thromboxane-induced platelet aggregation defect
Overview
What it is
This is an inherited blood clotting disorder affecting platelets, which are specialized blood cells responsible for stopping bleeding. In affected dogs, these platelets do not respond properly to thromboxane, a chemical signal that normally triggers them to clump together and form a clot. Because of this defect in the circulatory system, the dog's body cannot efficiently plug damaged blood vessels after an injury.
How it presents
Owners may notice frequent nosebleeds, bleeding gums, easy bruising, or unusually prolonged bleeding after minor scrapes. These signs are typically first noticed in young adulthood, often during routine procedures like spaying or neutering.
Treatment
While there is no cure, the condition can be managed through careful lifestyle adjustments to prevent injury. If surgery is necessary or an accident occurs, supportive treatments like transfusions may be required, with costs typically ranging from 500 to 3000 EUR.
