Abstract
- Adequate demonstration of the structures of the posterior fossa and the midline cerebral ventricular system is one of the most difficult problems in neuroradiology. During the last 2 years, we have performed conray ventriculography on 31 patients with clinical evidence of intracranial hypertension, in whom posterior fossa lesion was suspected or a supratentorial hemispheric lesion was not evident by carotid angiography. The patient is placed in the supine position and drilled 5cm above the nasion and 3cm to one side of the midline of nondominant hemisphere. A No. 20 spinal needle is inserted through the tract and aimed toward the anterior horn of the lateral ventricle. About 4 to 6 cc of conray is introduced into the anterior horn with head flexed. The head is slowly extended. Serial roentgenograms are used to follow the conray trough the ventricular system.
