Subdural hematoma secondary to CSF ventricular shunt.

The article reports on 8 cases of subdural hematoma consequent on 94 extrathecal CSF shunts inserted in 1977. Neuroradiolgical postoperative monitoning was carried out by CAT Scan and, where the neurological symptomatology required, cerebral angiography. The percentage of diagnosed subdural hematomas in relation to opening valve pressure, CSF opening ventricular pressure during surgery, and the hydrocephalus etiology, are discussed.
