[Microcirculatory bed of the serous membranes in hypertension].

In hypertension, all the components are affected in the microcirculatory bed of serous membranes: arterioles, precapillaries, capillaries, postcapillaries, venules, lymph capillaries and postcapillaries. Convolution of microvessels, formation of loops, skeins, torsions along the longitudinal axis, deformation of walls (folds and angularity of the contours, multiple unilateral and bilateral protrusions and invaginations, sacciform and cylindrical microaneurisms, multiplication of venules) are observed. In the control material collected from subjects who had died of various traumas vascular changes in serous membranes are poorly manifest or absent indicating a relative specificity of the microvessel involvement in hypertension. The results of the study are in accord with known from literature descriptions of changes in the microcirculatory bed of the eye conjunctiva observed in biomicroscopy in patients with hypertension which confirms the generalized nature of MCB involvement in this disease.
