Treatment of refractory partial status epilepticus with multiple subpial transection: case report.

Status epilepticus (SE) represents a medical emergency that annually affects 60,000--150,000 individuals in the United States. Selective neuronal loss in vulnerable areas has been pathologically demonstrated following convulsive SE primarily affecting the limbic system, thalamus and cerebellum. Morbidity in those cases that follow refractory SE (RSE) is poorly documented. There have been anecdotal reports of surgical treatment for this condition, especially secondary to brain lesions. We report a 6-year-old patient who was in RSE for 60 days, without a brain lesion documented by MRI. The patient underwent multiple subpial transection (MST) of the sensorimotor cortex, which by ictal EEG and ictal SPECT proved to be the epileptogenic zone. We conclude that MST should be considered as an alternative treatment for refractory partial SE. Copyright 2001 BEA Trading Ltd.
