Background:
To identify the role of acute surgical intervention in the treatment of refractory status epilepticus (RSE).
Methods:
Retrospective review of consecutive patients who underwent epilepsy surgery from 2006 to 2015 was done to identify cases where acute surgical intervention was employed for the treatment of RSE. In addition, the adult and pediatric RSE literature was reviewed for reports of surgical treatment of RSE.
Results:
Nine patients, aged 20-68 years, with various etiologies were identified to have undergone acute surgical resection for the treatment of RSE, aided by electrocorticography. Patients required aggressive medical therapy with antiepileptic drugs and intravenous anesthetic drugs for 10-54 days and underwent extensive neurodiagnostic testing prior to resective surgery. Eight out of nine patients survived and five patients were seizure-free at the last follow-up. The literature revealed 13 adult and 48 pediatric cases where adequate historical detail was available for review and comparison.
Conclusions:
We present the largest cohort of consecutive adult patients who underwent resective surgery in the setting of RSE. We also reveal that surgery can be efficacious in aborting status and in some can lead to long-term seizure freedom. Acute surgical intervention is a viable option in prolonged RSE and proper evaluation for such intervention should be conducted, although the timing and type of surgical intervention remain poorly defined.
