Obstructive hydrocephalus treated by ventriculocystocorticostoma.

The present report describes the late treatment of obstructive hydrocephalus in a patient in whom all conventional drainage techniques failed due to foreign-body reaction. A combination of subdural autodrainage and the ventriculostoma principle carried out by means of laser surgery was successful in achieving adequate drainage. The patient subsequently showed considerable improvement both clinically and psychologically after the operation. Sixteen months postoperatively the patient is in good health and a computed tomography scan confirmed well-functioning autodrainage.
