Brain vascular embolism

Description:

Brain vascular embolism — a vemboliya of vessels of a brain — sudden occlusion of a brain vessel an embolus, one of pathogenetic options of development of an ischemic stroke., one of pathogenetic options of development of an ischemic stroke.

Brain Vascular embolism symptoms:

The clinical picture is characterized by sudden emergence of neurologic symptoms. Often the embolism develops at persons of young age, as a rule, in the afternoon; it is provoked by a physical overstrain, a stress. The short-term loss of consciousness is characteristic, epileptic seizures and passing shell symptoms are quite often noted. Sometimes at the same time there is a retinal embolism with a sudden blindness or emergence of scotomas. If the disseminated fatty embolism is the reason of a stroke, then the neurologic symptomatology is preceded by pulmonary symptoms (short wind, cough, a pneumorrhagia) which are caused by emergence of fatty particles in vessels of lungs. Character of focal neurologic symptoms is defined by localization of a brain heart attack which corresponds to a zone of blood supply of the struck vessel. Embolisms in system of an internal carotid artery meet a little more often (in comparison with vertebrobazilyarny system).

Brain Vascular embolism reasons:

Along with obstruction of a vessel an embolus the innervatsionny disturbances (a vasospasm with the subsequent vazoparez) which are followed by wet brain, desolation of a capillary network in the pool of the struck vessel develop. At disappearance of a reflex spasm the embolus can move ahead in distal departments of a vessel, and then switched off there are only small cortical branches of arteries. Most often cardiogenic embolisms at valve heart diseases, a returnable rheumatic endocarditis, a subacute or bacterial endocarditis, myocardial infarctions meet, during operations for heart diseases, at the cardiosclerosis proceeding with atrial fibrillation and formation of pristenochny blood clots, etc. Character of emboluses various. It can be particles of the changed valves of heart, pristenochny blood clots and blood clots from an ear of the left auricle, pieces of the breaking-up atherosclerotic plaques at atherosclerosis of an aorta or the main vessels of the head, sometimes blood clots at a nonclosure of foramen ovale of an interatrial partition, from veins of a big circle of blood circulation (at thrombophlebitises of veins of extremities, vein thromboses of an abdominal cavity, small pelvis). In certain cases the embolism of brain vessels occurs at malignant tumors, purulent processes in lungs. The bacterial embolism can arise at endocarditises. Meet fatty less often (at a fracture of long tubular bones, at operations with big traumatization of hypodermic cellulose) and a gas embolism (at lung operations, imposing of pheumothorax, during the lacunar works).

Treatment of the Vascular embolism of a brain:

The treatment similar to that at a stroke is carried out.
