Subtemporal decompression for the slit-ventricle syndrome after shunting in hydrocephalic children.

During the past 2 years, we have performed subtemporal decompression to deal with recurrent shunt obstruction in 22 hydrocephalic patients with the slit-ventricle syndrome. 13 patients have been followed-up for more than 1 year and 2 others for more than 2 years. The frequency of hospitalization for shunt-revision has been greatly reduced. These results confirm that subtemporal craniectomy is useful in the treatment of patients in whom this syndrome develops.
