Successful radiofrequency ablation of the cerebral cortex in pigs using the venous system: possible implications for treating CNS disorders.

Abstract:

BACKGROUND:When pharmacotherapy for epilepsy fails, surgical options, although efficacious, are highly invasive. We explored whether ablation of the cerebral cortex can be performed utilizing the cerebral venous system. METHODS:Mapping and radiofrequency ablation was performed via the venous system in two pigs. RESULTS:Eight targeted sites were successfully accessed and four targeted sites successfully ablated via the central cerebral venous network. CONCLUSION:Electrophysiological mapping and radiofrequency ablation of the cerebral cortex can be performed via the cerebral veins.
