[Structural changes of the brain intraorgan arteries in different periods of experimental aortic coarctation].
Brain arteries of 10 control dogs and 25 dogs with a hemodynamic model of aorta coarctation are studied using a complex of methods. It is established that the following alterations arise in the course of the experiment: 1) hypertrophy and hyperplasia of the media smooth muscle cells in the arteries and arterioles 2) enhancement of the development of the oblique-longitudinal intimal muscles and muscular-elastic sphincters 3) reduction of the volume of the cerebral arterial bed, development of angiosclerosis and angiohyalinosis.
