[Duplex scanning of the changes in the vertebral arteries in patients with ischemic stroke in the vertebro-basilar basin].

With duplex scanning of neck vessels in 120 patients with acute ischemic stroke in the vertebrobasilar basin revealed changes in the vertebral artery in (68.3%) of patients, which cause difficulty in blood flow in the vessels of vertebro-basilar basin. Among them were seen often atherosclerotic stenoses (53.3%), deformation (11.7%) and abnormal discharge of vertebral arteries (3.3%).

[A new approach to the treatment of patients with circulatory encephalopathy]. / Novyi pidkhid do likuvannia khvorykh na dystsyrkuliatornu entsefalopatiiu.

Effects were studied of vincamin and tanakan in 68 patients with stage I, II and III discirculatory encephalopathy (as per WHO classification 1981). In 52% of the patients atherosclerosis of brain vessels was associated with arterial hypertension (group I), in 48 per cent venous discirculatory encephalopathy was diagnosable against the background of arterial hypertension (group IIA-20%) and arterial hypotension (group IIB-26%). Both tanakan and vincamin were found to be effective in group I patients; however, in stage III condition their effectiveness was no better than 42 and 15% respectively, which fact might be due to organic changes in the vascular wall. Tanakan appeared to be more beneficial in group II patients since venous dystonia is considered to be the main pathogenetic link in this context, and tanakan is known to improve the venous outflow from the cranial cavity. Almost in one-third of group IIB patients vincamin worsened general health status, especially so in stage III discirculatory encephalopathy, which fact may be related to peculiar effect of the drug on the arterial link of brain blood supply.

[The correlations between the arterial and venous components of the hemodynamics and cerebrospinal fluid pressure in arterial hypotension]. / Spivvidnoshennia mizh arterial'nym i venoznym komponentamy hemodynamiky ta likvornym tyskom pru arterial'nii hipotenziï.

A total of 30 patients with arterial hypotension were examined. Rheoencephalogrammes documented hypotension of the arterial and venous constituents of the brain in one third of the above patients (in those patients with physiological hypotension it was recordable more frequently): in one forth of those cases with primary arterial hypotension presenting with the cerebral crises, moderately severe venous and arterial hypotension was generally seen. In a major proportion of the examinees, a correlation was found between the drop in arterial pressure, vascular tension of the arterial vessels of the brain and an adequate state of the venous tension and liquor pressure. Roentgenography of the skull and ophthalmoscopy do not permit forming an opinion about liquor hypertension since it was not demonstrated on the computerized tomographic scans.
