Hypertension disturbances of cerebral blood circulation

Abstract

Hypertension is the main cause and the most important risk factor of various forms of temporary as well constant acute disturbances of cerebral blood circulation. Patients with more than 25 years hypertension and frequent increases of blood pressure have damages of brain vessels with plasmorrhage and fibrinoid necrosis
of capillaries walls. This damage in their turn being “hypertonic stenosis or occlusion” of brain vessels can lead to a disturbance of blood flow in the supplied regions and result in forming small lacunar brain infarctions, the most typical for arterial hypertension. From the other hand, necrosis of media vessels myocytes can lead to their sharp thinning, forming microaneurysm, that breaks and causes intracerebral hemorrhage. The presented clinical observation states different types of hypertension angiopathy in one patient and as a result different types of disturbances of cerebral blood circulation: cerebral hypertension stroke, repeated intracerebral hemorrhage and small lacunar brain infarctions.
