  • Title: [The structural reorganization of the arteries of the brain and kidneys in experimental aortic coarctation].
    Author: Ial'tsev AV, Shormanov SV.
    Journal: Morfologiia; 2000; 117(1):29-33. PubMed ID: 10876774.
    Abstract:
    Structural changes of cerebral and renal arteries were studied in 25 dogs with hemodynamic model of aorta coarctation and 10 control animals using histological, histochemical and morphometric methods. It was established in aorta coarctation due to growth and decrease of blood supply into cerebral and renal basins a series++ of compensatory adaptive, adaptive and pathological changes develop in vessels. The first are manifested in cerebral arteries through hypertrophic and hyperplastic changes of media smooth myocyte circular musculature, the second in renal arteries they are manifested through these musculature atrophy. The second--through the development of oblique-longitudinal musculature; the latter--through the reduction of these vessels lumen and the developments of angiosclerosis and angiohyalinosis.
