[Changes in the ventricular system of the brain in epilepsy patients (according to the results of echoventriculometry, planimetric pneumoencephalography and clinical examination)].

Examination of 120 epileptics with the use of pneumoencephalography (PEG) and echoventriculometry (EVM) demonstrated that the changes in the cerebral ventricular system could be pinpointed as early as during the first year of the disease and that later on they had a tendency for gradual progression. These changes are hardly dependent on the total duration of epilepsy but the severity of its course exerts a marked influence on them. A comparative analysis of the EVM and PEG readings as well as cerebrospinal fluid pressure values suggests that the results provided by these methods show good correlation and that in some cases it is possible to limit the work-up of patients to echoventriculometry as a sufficiently informative and safe method, without resorting to pneumoencephalography.
