Postoperative complications of meningioma include hemorrhage, neurological damage, infection, epilepsy and so on. Meningioma surgery includes traditional craniotomy and minimally invasive surgery, which will inevitably cause damage to blood vessels during surgery, leading to different degrees of bleeding, and when larger blood vessels are damaged, it can lead to the occurrence of hemorrhage or shock. During surgery, normal tissues or nerves of the skull and brain may also be damaged, leading to neurological deficits and symptoms such as hemiparesis and aphasia. The incision will be sutured after surgery, and if the incision is not properly cared for, it may become infected, and in severe cases, it may also lead to intracranial infection. In addition, the process of surgical removal of meningeal tumors may damage the cerebral cortex, causing abnormal discharges in the cerebral cortex, which in turn may cause epilepsy. There are more complications that may occur after meningioma surgery, so it is recommended that patients should seek medical treatment in time when abnormalities occur, and standardize the treatment under the guidance of professional doctors.
