[Structural changes in the kidney vessels in nephropathies and hypertension]

Morphological changes of the renal blood vessels were studied in 143 patients with different nephropathies and hypertensive disease. Vessels wall changes proper included: fibroelastosis, hyalinosis as well as antibodies to smooth muscle cells observed exclusively in the development of arterial hypertension. The changes were more pronounced in severe and durable hypertension. Perivascular sclerosis was found almost in all hypertensive patients and in some normotonic patients with aggravated heredity for arterial hypertension. The obtained data allow to frame a hypothesis on the role of formation of perivascular sclerosis as a reflection of repeated vascular spasm, subsequent increase of the peripheral resistance in the pathogenesis of development of arterial hypertension.
