Hemispherectomy for Sturge-Weber syndrome
Insights
Early hemispherectomy surgery in infants with Sturge-Weber disease effectively controls seizures and minimizes neurological deficits. This intervention leads to positive outcomes, preventing severe hemiplegia and dementia in affected children.
Area of Science:
- Pediatric Neurology
- Neurosurgery
- Genetics
Background:
- Sturge-Weber disease often leads to severe neurological impairment, including intractable seizures, hemiplegia, and cognitive deficits, particularly when seizure onset is in infancy.
- The progressive nature of the disease necessitates early and effective interventions to alter the typical downhill course.
Purpose of the Study:
- To evaluate the efficacy of early hemispherectomy in infants diagnosed with Sturge-Weber disease and experiencing infantile-onset seizures.
- To assess the impact of hemispherectomy on seizure control, motor function, and cognitive development.
Main Methods:
- A retrospective review of 6 infants under 1 year of age who underwent hemispherectomy for Sturge-Weber disease and intractable seizures.
- Analysis of seizure frequency, neurological examination findings (hemiparesis), and developmental assessments post-surgery.
Main Results:
- All 6 patients achieved complete seizure cessation following hemispherectomy.
- Post-operative neurological assessments revealed minimal hemiparesis.
- Intellectual development in the patients was reported as good, contrasting with the expected severe dementia.
Conclusions:
- Early hemispherectomy is a highly effective treatment for infants with Sturge-Weber disease presenting with infantile-onset seizures.
- This surgical approach can prevent severe neurological sequelae, including intractable epilepsy, profound hemiplegia, and dementia, leading to favorable long-term outcomes.
Abstract:
Patients with Sturge-Weber disease who have the onset of seizures in infancy invariably face a progressively downhill course which leaves them severely hemiplegic, demented and usually institutionalized because of uncontrolled seizures. During the past 12 years, we have carried out 6 hemispherectomies in infants under 1 year of age who presented with seizures and Sturge-Weber disease. The results have been gratifying. Seizures have stopped, hemipareses have been minimal and intellectual development has been good.
