Insights
Temporoparietooccipital disconnection effectively treats pediatric intractable epilepsy caused by posterior quadrantic cortical dysplasia. This surgical strategy resulted in a high seizure-free rate among young patients.
Area of Science:
- Pediatric Neurology
- Neurosurgery
- Epileptology
Background:
- Pediatric intractable epilepsy poses significant challenges.
- Posterior quadrantic cortical dysplasia is a specific etiology requiring targeted treatment.
Purpose of the Study:
- To detail clinical features of pediatric intractable epilepsy from posterior quadrantic cortical dysplasia.
- To evaluate the efficacy of temporoparietooccipital disconnection as a surgical strategy.
- To assess surgical outcomes in affected children.
Main Methods:
- Retrospective analysis of 14 children with posterior quadrantic cortical dysplasia.
- Evaluation of video-electroencephalography and intraoperative monitoring for localization.
- Assessment of temporoparietooccipital disconnection indications and outcomes.
Main Results:
- Spasm was the most frequent seizure type observed.
- Cortical dysplasia involved the central cerebral region in 2 cases.
- 13 out of 14 patients achieved seizure freedom post-surgery; one patient had a >50% seizure frequency reduction.
Conclusions:
- Temporoparietooccipital disconnection is a safe and effective surgical intervention.
- This procedure offers significant benefits for pediatric intractable epilepsy due to posterior quadrantic cortical dysplasia.
Objective:
To investigate the clinical features and surgical strategy for pediatric intractable epilepsy due to posterior quadrantic cortical dysplasia and to assess the surgical outcomes.
Methods:
The clinical features and preoperative evaluation results of 14 children with intractable epilepsy due to posterior quadrantic cortical dysplasia were retrospectively analyzed. The localization values of video-electroencephalography and intraoperative monitoring and the indications, advantages and disadvantages of temporoparietooccipital disconnection were evaluated.
Results:
The 14 children had different seizure types, of which spasm was the most common one. The lesions of cortical dysplasia involved the central cerebral region in 2 cases. After temporoparietooccipital disconnection in 14 patients, 13 cases were seizure-free; only one case still had seizures, but the frequency dropped by more than 50%.
Conclusions:
Temporoparietooccipital disconnection is a safe and effective surgical procedure for children with intractable epilepsy due to posterior quadrantic cortical dysplasia.
