Зміна судин міокарду при повній транспозиції магістральних судин

Abstract

The 46 hearts with the transposition of the great vessels and 20 biopsies was studied. The ligth-optically and polarizatio-optically investigations was used. The histologycal material is characterized bу vascular spasm, hemon-hage, foolblood, plethora, aggregation red blood cells and trombocytes, proliferation and swellsing of endothelium of the small vessels. In the myocardium is present а connection between vascular spasm of the different calibers of arteries and cardiomyocytes lesion, different sclerosis.
