The risk of intracranial space-occupying surgery should be assessed based on the location, size, benignity and malignancy of the tumor, and the risk cannot be generalized.
For some benign and superficial tumors, which usually do not infiltrate into the surrounding tissues, the surgery can usually achieve complete resection, and the patient’s symptoms can be significantly relieved after the surgery, such as dizziness, headache symptoms reduced or disappeared, the risk of the surgery is relatively small, and generally will not leave obvious sequelae.
If the tumor grows in key areas, such as around the thalamus and brainstem, the risk of surgery is higher, and if the brainstem is damaged during the operation, the patient’s respiration and heartbeat may be affected. At the same time, if the tumor is malignant, it will usually infiltrate into the surrounding tissues, and the surgery is more difficult, usually cannot be completely removed, and the patient has to be supplemented with radiotherapy after the operation, and there may be more obvious after-effects.
At the same time, the size of the surgical risk is also related to the medical level of the hospital, high medical level, accurate positioning, meticulous operation can effectively reduce the risk of surgery.
