The patient had a 32 mm × 28 mm meningioma that compressed the brainstem, causing the brainstem to shift and was subsequently removed. One month after the operation, due to the inability to absorb hydrocephalus and leakage of hydrocephalus, craniophlegm, and lumbar cisterna drainage were performed. Patients with subsequent intracranial infections were accompanied by high fever and loss of energy for one week. After the intracranial infection was controlled, the patient was in a coma for about 48 hours, and after CT examination, the patient's ventricles were enlarged, hydrocephalus could not be absorbed, and the intracranial pressure was higher than normal. On the second day of the examination, a peritoneal shunt was performed, after which the patient experienced a sudden drop in heart rate accompanied by coma, and there were several subsequent occurrences.The heart rate returned to normal and consciousness returned. The reason is unknown at present, if you know, please let me know.
