Glioma is a common malignant intracranial tumor with a high recurrence rate and there is no direct and complete cure, only surgery, radiotherapy or chemotherapy to prolong the life of patients. Many people are worried about the complications after glioma surgery, so they dare not operate. What are the common complications after glioma surgery? 1. Cerebral edema and increased intracranial pressure: After glioma surgery, cerebral edema and increased intracranial pressure may occur, so dehydrating drugs can be used to reduce intracranial pressure and glucocorticoids to reduce cerebral edema. For tumors with extensive lesions or high malignancy, the tumor and non-functional brain tissues can be removed as much as possible for internal decompression and external decompression with bone flaps. Intracranial hemorrhage or hematoma: Some patients with glioma may have intracranial hemorrhage or hematoma after surgery, which is related to the lack of careful intraoperative hemostasis, but with the improvement of surgical skills, this complication is less likely to occur. Careful hemostasis of the trauma and repeated irrigation before cranial closure can reduce or avoid postoperative intracranial hemorrhage. 3, neurological deficits: This is related to intraoperative injury to important functional areas and important structures, which should be avoided as much as possible during surgery and treated symptomatically after occurrence. There are many patients will have postoperative complications, such as epilepsy, convulsions are very common. Complications after glioma surgery can be divided into systemic and localized. Neurological complications include speech, vascular damage, and blurred vision. Neurological complications include speech, vascular damage, blurred vision, edema, and sensation. Local complications include wound infection, wound cerebrospinal fluid leakage, epilepsy and hydrocephalus. Other systemic complications include deep venous thrombosis, pneumonia, etc. On the basis of this classification, it can be further divided into severe and minor complications according to the degree of injury. Severe postoperative glioma complications can be permanent and irreversible, and patients cannot survive independently and have a reduced quality of life. Mild comorbidities can exist for a short time and can be recovered with little impact on the patient’s quality of life.
