Ultrasound In The Crowd Of Stroke And High-risk Groups Of Carotid Plaques Comparative Study

Objective:Stroke is a kind of sudden onset of cerebral blood circulation disorder, is our country the current common disease, frequently-occurring disease of cerebrovascular disease, serious or even life-threatening. Some factors for the occurrence of cerebral apoplexy has a close relationship, known as risk factors, can be divided into two categories, one kind is unable to intervene, are usually decided by age, heredity and genes, another kind is to intervene, such as high blood pressure, high cholesterol, diabetes, smoking and coronary heart disease, obesity, alcohol, etc, through control, can reduce the morbidity and mortality of cerebral apoplexy, cerebral apoplexy occurs most was vascular stenosis caused by atherosclerotic plaque formation and plaque damage caused thrombosis fall off, so the stroke sicken the crowd also high risk of recurrence of stroke. Carotid artery is the main way of brain blood supply, carotid artery plaque formation on the occurrence of cerebral apoplexy has important clinical significance, based on the stroke in people162and high-risk groups of1861cerebral apoplexy of carotid artery with color doppler ultrasound and contrast analysis of the test results, to explore color to exceed to crowds of stroke and stroke in people at high risk of carotid plaque detection application value.Method:application of color to exceed to stroke population162people with high-risk groups,1861cases of cerebral apoplexy in carotid plaques, the two groups in age groups, divided into41to50years old group,51to60years old group,61-70years group and more than70-year-old group, the observation group and plaque of carotid artery intima-media condition, understand the presence of carotid atherosclerosis, plaque into low echo plaques, hypoechoic plaque, strong echo of plaque, the plaque has narrow patient record, comparative study on the final stroke population of different age groups and the degree of hardening of the arteries in high-risk groups, and narrow, and analyze the factors and the relationship between the carotid atherosclerosis. Compare with stroke population size again suffering from the risk of stroke in high-risk groups.Results:in all age groups above40years old people, age, higher incidence of atherosclerotic plaque, severity of the heavier; Age groups at various stages, the crowd incidence of atherosclerosis and stroke severity were higher than in high-risk groups, stroke patients crowd plaque to narrow stroke prevalence were higher than in stroke patients with high-risk groups.Conclusion:the statistics, the age has an important effect on the incidence of atherosclerosis. As the growth of the age, blood vessels can itself have certain physiological changes, artery vascular tissue cells in ageing, and will be more exposed to risk factors, such as high blood pressure, diabetes, coronary heart disease, high cholesterol, smoking and so on, so age is one of the immutable factors of atherosclerosis occurs. Another, according to the results of the morbidity and severity of carotid atherosclerosis in patients with stroke are also at higher risk of stroke is high, the stroke patients with cerebral infarction, the main reason is the plaque forming narrow or damaged caused cerebral arterial thrombosis fall off distal vascular infarction, and the research proves that the number of stroke patients with carotid artery plaque formation than in patients with high-risk groups, further illustrate arteriosclerosis of the close relationship with the onset of stroke, plaque, the vascular stenosis or plaque worn more opportunity, and stroke patients are high-risk groups are more likely to again cerebral thrombus formation, so the ultrasonic and people at high risk of stroke in patients with stroke in detection of carotid plaques and follow-up have important clinical significance.
