Down syndrome associated moyamoya may worsen epilepsy control and can benefit from surgical revascularization

摘要

ObjectivesTo examine outcome of bilateral extracranial to intracranial (EC-IC) bypass surgeries for a Down syndrome patient with hard-to-treat epilepsy and moyamoya.Materials and methodsSuperficial temporal arteries were anastamosed using an indirect bypass technique to middle cerebral arteries bilaterally to help limit perfusion deficits and seizure controls.ResultsTwo superficial temporal to middle cerebral artery indirect bypass surgeries were performed within 3?months. Post-revascularization improvements included seizure control, gait, perfusion, wakefulness, language and quality of life.ConclusionIn patients with Down syndrome and moyamoya, improvements in seizure control and quality of life may occur with EC-IC bypass procedures.
