Stereotactic evacuation of hematoma has been reported to reduce the incidence of mortality and improve functional outcomes in patients with spontaneous ICH, especially in those with hemorrhage within the putamen.1,3,5–7,13,14,16,19–22,24–26,33,34,37,38 Stereotactic evacuation of hematoma has not been widely accepted as a standard therapy for treating spontaneous ICH, however, because its effect on functional outcome has been regarded as marginal and there has been no randomized trial of this procedure. We therefore conducted our original randomized trial in patients with putaminal hemorrhage in an attempt to evaluate the effectiveness of stereotactic evacuation of hematoma.
