The rightward shift of the midline of the brain after glioma surgery can be due to the patient’s postoperative cerebral hemorrhage or cerebral edema. 1. Cerebral edema: after glioma surgery, patients often have cerebral edema, and need to review the cranial CT to see the severity of cerebral edema. If the cerebral edema is not serious and the midline shift is not obvious, you can follow the doctor’s instructions to use mannitol, glycerol fructose, etc. to reduce intracranial pressure and protect the normal brain tissues from further damage, so as to avoid the emergence of limb dysfunction in the later stage. 2. Cerebral hemorrhage: clinically, some patients may have cerebral hemorrhage after glioma surgery, which is a serious complication. A small amount of cerebral hemorrhage, the midline shift is not obvious, and most patients will have cerebral hemorrhage subsided in 2~3 weeks after active treatment. If the amount of cerebral hemorrhage is large, the patient’s life may be in danger, and it is often necessary to perform another craniotomy to remove the hematoma to save the patient’s life. Once you find that the center line of the brain is shifted to the right, you need to repeat the CT examination to clarify the cause and actively cooperate with the doctor to avoid delaying the condition.
