[State of the cerebral ventricular system in cerebral autonomic vascular paroxysms (clinico-echoencephalographic study)].

For diagnosing hydrocephalus of the third ventricle in cases of affections of the hypothalamic region use was made of echoencephalography. Under examination there were 71 patients with hypothalamic vegetovascular paroxysms, as well as 40 healthy subjects that constituted the control group. It was found that in the healthy subjects the width of the third ventricle varied from 3. to 5.5 mm, being 4.60 +/- 0.65 mm on the average. Of the 71 patients with the hypothalamic affections, hydrocephalus of the ventricle was revealed in 56, and the ventricle width varied within 7 to 12.5 mm, most frequently within 7 to 10 mm. In 19 patients the echoencephalographic findings were compared with pneumoencephalographic ones. On the echoencephalography a dilatation of the third ventricle was revealed in 16 of them, and on the pneumoencephalography in all. Thus, echoencephalography enables one to diagnose hydrocephalus of the third ventricle in most patients with affections of the hypothalamus region.
