Fever on the fourth day after minimally invasive surgery for cerebral cysts may be caused by damage to the thermoregulatory center, postoperative absorption of heat and postoperative infection.
1. Damage to the thermoregulatory center: the thermoregulatory center is located in the hypothalamus, if the operation site is close to the hypothalamus, on the fourth day after the operation, due to the congestion and edema of the brain tissues, it is possible to damage the thermoregulatory center, and fever symptoms will appear.
2. Postoperative absorption fever: after minimally invasive surgery for brain cysts, there may be some sterile necrotic substances in the local area, which will be gradually absorbed on the fourth day after surgery, and fever may also appear at this time.
3. Postoperative infection: on the fourth day after minimally invasive surgery for cerebral cysts, the patient’s body is relatively weak, and intracranial infection and lung infection may occur, which will also cause fever.
If fever occurs on the fourth day after minimally invasive surgery for brain cysts, the patient should be actively examined in order to clarify the cause of the disease, monitor the change of body temperature, and actively carry out treatment under the guidance of the doctor.
