[Morphological properties of erythrocytes and their deformability in cerebral circulatory disorders in patients with arterial hypertension].

Using a scanning electron microscope, the authors examined changes in the shape of erythrocytes (E) in 85 patients with impaired cerebral circulation (ICC). Parallelly 48 patients were studied for the deformity and osmotic resistance of E. The control group consisted of 17 healthy individuals. The data obtained suggest significant alterations in the shape and functional properties of E in patients with ICC which correlated with parameters of blood viscosity and E aggregation. The degree of changes was determined by the duration of the underlying vascular disease, recurrent episodes of ICC and their severity.
