Introduction
Edema following glioma surgery can be treated with dehydration medication under medical guidance, and it generally gradually improves within one to two weeks. However, if the edema is caused by venous injury during surgery leading to impaired venous return and results in severe persistent edema, additional surgery or other treatments are usually required, and the recovery time in such cases is typically unpredictable.
Postoperative edema following glioma surgery typically resolves within 1–2 weeks.
Gliomas are a group of tumors that primarily invade the brain and spinal cord. After surgical resection, trauma to brain or spinal cord tissue inevitably leads to varying degrees of cerebral or spinal cord edema. Edema usually peaks around postoperative day 3. Under physician guidance, dehydration therapy—commonly using agents such as mannitol or glycerol fructose—can be administered to manage this condition; symptoms generally improve gradually over 1–2 weeks. However, if venous injury occurs during surgery—resulting in impaired venous return and causing severe, persistent malignant edema—additional interventions, such as repeat surgery or other therapeutic modalities, may be required to mitigate edema progression and promote resolution. In such cases, the recovery timeline is often unpredictable.
After glioma surgery, patients should maintain a light, easily digestible diet and consume foods rich in protein and vitamins to support recovery. However, strenuous physical activity must be avoided to prevent interference with healing.
