[Angiographic and morphologic criteria of the manifestation of arteriolonephrosclerosis in vasorenal hypertension].

Parallel comparison of angiographic and morphologic indices of arterial nephrosclerosis levels was performed in 34 patients with vasorenal hypertension secondary to unilateral lesion of renal arteries. Coefficient of vascular picture absence zone in the kidney (30) presenting a percentage ratio of a vascular zone of kidney cortical layer and the total area of its section was employed. Amount of vascular index (ratio between the wall density of afferent glomerular arteriole and its lumen diameter) was used to assess arteriolosclerosis in morphologic examination of renal biopsy specimens. High level of reliable coefficient 30 in the evaluation of arteriolar nephrosclerosis degree was substantiated morphologically. Critical level of coefficient 30 was stated for the affected and contralateral kidneys, and its increase was suggestive of irreversible sclerosis of renal microvascular bed.
