Epilepsy and Lesionectomy

What Happens After a Lesionectomy?

After a lesionectomy, the patient generally stays in an intensive care unit for 24 to 48 hours after surgery and then stays in a regular hospital room for three to four days. Most people who have a lesionectomy will be able to return to their normal activities, including work or school, in six to eight weeks after surgery. Most patients will need to continue taking anti-seizure medication. Once seizure control is established, medications may be reduced or eliminated.

How Effective Is a Lesionectomy?

Lesionectomy results are excellent in patients whose seizures are clearly associated with a defined lesion. Seizures usually stop once the lesion is removed.

What Are the Side Effects of a Lesionectomy?

Side effects of a lesionectomy vary, depending on the location and extent of the lesion and the tissue removed. The following side effects may occur after surgery, although they generally go away on their own:

• Scalp numbness
• Nausea
• Feeling tired or depressed
• Headaches
• Difficulty speaking, remembering, or finding words

What Risks Are Associated With a Lesionectomy?

The risks associated with lesionectomy include:

• Risks associated with surgery, including infection, bleeding, and an allergic reaction to anesthesia
• Failure to relieve seizures
• Swelling in the brain
• Damage to healthy brain tissue
