Corticotomy Closure Avoids Subdural Collections After Hemispherotomy

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.
