The treatment is mainly vascular decompression surgery. 2, headache, headache after surgery is mainly due to low cranial pressure caused by excessive drainage, and secondly, it may also be caused by the stimulation of bloody cerebrospinal fluid. For some patients, it may be caused by intracranial infection, cerebral hemorrhage, cerebral edema and other increased intracranial pressure. 3, epilepsy, if epilepsy occurs, anti-epileptic treatment is needed. 4, wounds and cerebrospinal fluid leakage, for the occurrence of wounds and cerebrospinal fluid leakage of the patient, lumbar puncture drainage of infected cerebrospinal fluid is needed, so as to make the intracranial infection get effective control and wound healing.
