Hypersplenism can cause a decrease in whole blood cells, which in turn can lead to symptoms such as anemia, infection and bleeding. When accompanied by decreased liver function or the occurrence of coagulation dysfunction, more serious bleeding symptoms occur, which can be life-threatening. Traditional treatment: Surgical removal of the spleen, advantages: precise efficacy. Disadvantages: small trauma, high risk, many complications. For (1) myelosclerosis (2) chronic granulocytic leukemia (3) hypersplenism caused by certain non-hematological disorders such as sepsis, black fever, syphilis, etc., splenectomy cannot be performed. In addition, the spleen, as an immune organ, plays an important role in maintaining normal immune function, preventing and controlling infection and preventing tumor growth, and cannot be removed casually. Interventional treatment: No surgery, only partial splenectomy is used. Advantages: It can effectively improve hypersplenism, preserve the immune function of the spleen, improve bone marrow function, and have few complications.
