Early modified functional hemispherectomy in a young infant with Ohtahara syndrome and hemimegalencephaly

Area of Science:

• Pediatric Neurology
• Neurosurgery
• Epileptology

Background:

• Ohtahara syndrome is a severe early-infantile epileptic encephalopathy.
• Hemimegalencephaly, characterized by an enlarged cerebral hemisphere, can be associated with intractable epilepsy.
• Early diagnosis and intervention are crucial for managing these complex pediatric neurological conditions.

Purpose of the Study:

• To report the case of the youngest infant undergoing modified functional hemispherectomy.
• To evaluate the efficacy of early surgical intervention for Ohtahara syndrome with underlying hemimegalencephaly.
• To assess seizure control and psychomotor development outcomes post-surgery.

Main Methods:

• Modified functional hemispherectomy performed at 5 months of age.
• Case study reporting on a single infant.
• Post-operative assessment of seizure frequency and developmental milestones.

Main Results:

• The infant, treated at 5 months, demonstrated favorable seizure control post-operatively.
• Significant improvements in psychomotor development were observed.
• The surgical approach was associated with positive clinical outcomes.

Conclusions:

• Early surgical intervention, specifically modified functional hemispherectomy, may be a viable treatment option for infants with Ohtahara syndrome and hemimegalencephaly.
• Prompt surgical management can lead to improved neurological outcomes, including seizure reduction and developmental progress.
• This case highlights the potential benefits of aggressive early treatment strategies in severe pediatric epilepsy syndromes.
