Subtemporal decompression for slit-ventricle syndrome: successful outcome after dramatic change in intracranial pressure wave morphology

Abstract

Subtemporal decompression is recognized as an effective treatment for slit-ventricle syndrome; however, the effects of this procedure have not been demonstrated using both pre- and postsurgical intracranial pressure (ICP) monitoring. The authors report two cases in which slit-ventricle syndrome and elevated ICP had been diagnosed. Each patient underwent ICP monitoring before and after subtemporal decompression; the dramatic changes in the ICP measurements are presented along with findings from 1-year follow-up examinations.
