A survey of preferences and expectations for surgical interventions targeting atonic seizures in Lennox-Gastaut syndrome.

ABSTRACT

PURPOSE: To assess preferences and outcome expectations for vagus nerve stimulation (VNS) and corpus callosotomy (CC) surgeries in the treatment of atonic seizure in Lennox-Gastaut syndrome (LGS). METHODS: A total of 260 surveys were collected from patients are caregivers of LGS patients via Research Electronic Data Capture (REDCap). RESULTS: Respondents reported an average acceptable atonic seizure reduction rate of 55.9% following VNS and 74.7% following CC. 21.3% (n = 50) were willing to be randomized. Respondents reported low willingness for randomization and a higher seizure reduction expectation with CC. CONCLUSION: Our findings guide surgical approaches for clinicians to consider patient preference in order to design future studies comparing effectiveness between these two procedures.
