In primary thrombocythemia, low-risk patients do not need to be hospitalized, and high-risk elderly patients need to be hospitalized. 1. Primary thrombocythemia is also called idiopathic thrombocythemia and hemorrhagic thrombocythemia. Low-risk patients who are asymptomatic or have mild symptoms usually do not require hospitalization. 2. High-risk elderly patients with spontaneous bleeding (recurrent) such as gastrointestinal bleeding, gum bleeding, purpura, etc., or thrombosis such as venous thrombosis, lower extremity vascular embolism splenomegaly and other symptoms require hospitalization. Therefore, primary thrombocythemia is a relatively dangerous disease, and different treatments can be given depending on the condition to avoid delaying the condition. Specific treatment should be carried out under the guidance of a physician.
