Corticotomy closure avoids subdural collections after hemispherotomy

Abstract

Background: Subdural collection is a possible adverse event that can occur after hemispherotomy.

Objective: : We describe our surgical technique to avoid subdural collection after peri-insular hemispherotomy in children.

Methods: Since 2008, we have closed the corticotomy with interrupted pial sutures and fibrinogen glue in 16 patients.

Results: This operative technique stopped the occurrence of postoperative subdural collection and was not associated with an increased incidence of postoperative hydrocephalus.

Conclusion: We recommend closing ventricular access after functional hemispherotomy, notably in patients who have had a stroke.
