Final answer:
Thrombocytopenia is a condition with low platelets leading to excessive bleeding; normal PT and PTT imply intact coagulation pathways. Causes vary and treatment may include corticosteroids, IVIG, or platelet transfusions.
Step-by-step explanation:
Causes and Treatment of Thrombocytopenia with Normal PT and PTT Thrombocytopenia is a condition characterized by an abnormally low number of platelets, which can lead to excessive bleeding. If a patient with thrombocytopenia presents normal PT (Prothrombin Time) and PTT (Partial Thromboplastin Time), it suggests that the coagulation pathways are intact, but the platelet count is decreased.
Causes of thrombocytopenia with normal PT and PTT include bone marrow disorders, increased platelet destruction (as in immune thrombocytopenia or drug-induced thrombocytopenia), and dilutional thrombocytopenia after transfusions. Treatment depends on the cause and the severity of the condition, but may involve corticosteroids, intravenous immunoglobulin (IVIG), or platelet transfusions.
