Immediate and late effects of ventricular shunting in infantile hydrocephalus.

This paper analyzes our findings in a series of 1900 CT examinations carried out on 950 children after ventricular drainage. Blood in the ventricles is a relatively frequent findings in the immediate postoperative course, and gliotic or poroencephalic phenomena are often found in the late course. Persistence of ventricular dilatation and periventricular lucency has been observed several times. Extracerebral collections and septic complications are not rare findings, but trapped fourth ventricle and choroidal-ependymal reactions are only rarely observed.
