If the spleen ruptures 3 cm, whether the spleen needs to be removed or not should not depend on how long the rupture is, but should focus on whether the blood pressure and hemoglobin are decreasing progressively, and whether there is a progressive increase in the blood accumulation in the abdominal cavity. Whether the spleen needs to be removed after rupture is not related to the length of the ruptured spleen, but should be analyzed according to the patient’s blood pressure and hemoglobin indexes to determine whether surgical treatment is needed. When the degree of splenic rupture is severe, resulting in a rapid drop in blood pressure and hemoglobin and a risk of ischemic shock, surgery is generally recommended as soon as possible. Whether surgery is needed after splenic rupture should also be analyzed according to the patient’s abdominal blood accumulation. Once the amount of blood accumulated in the abdominal cavity is found to be increasing progressively, resulting in blood volume insufficiency, surgery should be carried out immediately, and blood transfusion treatment should also be provided in the process. If the rupture of the spleen reaches 3cm, it is necessary to seek medical treatment in time to avoid delaying the condition, otherwise the consequences will be very serious.
