Spleen thrombocytopenia
Web7 Mar 2024 · In healthy individuals, approximately one-third of total platelets (thrombocytes) are stored in the spleen. In health disturbances followed by spleen enlargement (splenomegaly), the amount of platelets sequestrated in the spleen increases up to 90%, resulting in thrombocytopenia (a low number of platelets in circulating blood). WebThrombocytopenia is the condition in which there is a lower than normal concentration of platelets in the blood. This can happen for a number of reasons but most commonly in dogs, it is due to their insufficient production in the bone marrow or to platelets being destroyed.
