The risk of surgery with high preoperative platelets is the tendency to form blood clots, which may be life threatening. With mildly high preoperative platelets, the risk of surgery is not very high. However, significantly high preoperative platelets may lead to disseminated intravascular coagulation, causing blockage of blood vessels, which can lead to the formation of blood clots. If a patient with cerebral embolism develops a cerebral thrombus, limb dysfunction and, in severe cases, hemiparesis may occur. Blood clots lead to pulmonary embolism, which may lead to microcirculatory failure and is easily life-threatening. Therefore, high preoperative platelets have certain surgical risks, it is recommended to actively cooperate with professional doctors to take medication for platelet control, such as aspirin, interferon, etc., to reduce platelets to normal, and then carry out surgical treatment to avoid triggering some serious consequences. After the operation, the lower limbs should be massaged properly under the guidance of professional doctors, which can prevent the formation of blood clots.
