What should be done if there is severe edema after craniotomy?

Severe cerebral edema following craniotomy can be alleviated through pharmacological or surgical interventions.

1. Pharmacological Treatment

Cerebral edema after craniotomy typically results from direct injury to and disruption of brain tissue. If edema is severe, osmotic diuretics—such as glycerol fructose and mannitol—may be administered under physician guidance to increase plasma osmotic pressure and thereby reduce cerebral edema.

2. Surgical Treatment

In cases where severe post-craniotomy edema fails to respond adequately to medical management, decompressive craniectomy (i.e., re-craniotomy with bone flap removal) may be required. However, this procedure carries substantial surgical trauma and is reserved as a life-saving measure; its use must therefore be carefully individualized based on the patient’s specific clinical condition.

Following craniotomy, patients should maintain a light, nutritionally balanced diet, avoiding raw, cold, or highly irritating foods to prevent adverse effects on recovery. Additionally, early and active rehabilitation training is essential to prevent muscle atrophy.
