Morphological features of ischemic and hemorrhagic brain strokes

Abstract

The article is devoted to pathomorphological features of ischemic and hemorrhagic brain strokes. The aim of the research was to establish morphological peculiarities of brain stroke development in the basins of carotid, vertebralbasilar and both arterial systems. The analysis of 50 cases of tanatological study in which acute cerebral blood circulation disorder was diagnosed was carried out. It has been established that changes in the microcirculatory channel vessels during a hemorrhagic stroke are caused by hypoxia and ischemia of the brain, its swelling, and a sharp violation of vascular permeability. Such changes are local and widespread, can be divided into acute, which occurred during a stroke, and chronic, which developed before the stroke. Pathomorphological changes cover all structural and functional levels of the arterial system of the brain, the most important of which are the vessels of the microcirculatory channel.
