Is streamlined evaluation of children for epilepsy surgery possible?

Area of Science:

• Pediatric Neurology
• Epilepsy Surgery
• Neuroimaging

Background:

• Presurgical evaluation for pediatric intractable epilepsy involves clinical assessment, MRI, EEG, and functional imaging.
• The specific impact of each diagnostic tool on surgical decisions remains unclear.

Purpose of the Study:

• To systematically assess the contribution of MRI, EEG, and SPECT in surgical decision-making for pediatric epilepsy.
• To evaluate the influence of imaging and electroencephalography findings on offering epilepsy surgery.

Main Methods:

• Retrospective analysis of surgical eligibility decisions for 353 children with epilepsy.
• Utilized Quick Unbiased Statistical Tree (QUEST) to analyze relationships between MRI, EEG, SPECT, and surgical recommendations.

Main Results:

• 92% of children with localized MRI lesions were offered resective surgery, with EEG telemetry not significantly altering this decision.
• For those with bilateral or normal MRI, localized EEG onset increased surgery offers (78% vs. 9% for non-localized onset).
• SPECT findings did not consistently influence surgical decision-making across groups.

Conclusions:

• Localized MRI lesions in pediatric epilepsy may not require ictal EEG or SPECT for surgical candidacy assessment.
• More focused EEG telemetry could identify additional surgical candidates without escalating resource use.
