Comparison Of IMT And Plaques Of Carotid Arteries Between Young Patients With Hyperlipidemia And Normal Controls By Using Ultrasound With Vascular Enhancement Technology(VET)

Objective:High-frequency ultrasound technology combined with vascular enhancement technology (VET) can be applied to examine IMT and plaques of carotid arteries in hyperlipemia cases. This article is to discuss the potential value of this combined technology in cases of young patients with hyperlipemia.Methods:Set two groups:Group One, the experimental group, consists of 100 hyperlipemia patient under the age of 45:Group two. the control group, consists of 100 people with a normal blood-fat level. Keep other variables identical in the two group, including age. gender, blood pressure and blood sugar.Examine the two groups with the combination of high-frequency ultrasound technology and vascular enhancement technology (VET). Main statistics of observation are carotid artery diameter, carotid arterial Intima-media thickness (IMT), atheromatous plaqued.type and distribution..Use statistical software SPSS 11.5 in processing the statistics.measurement data to x±s says,using t-test.Counting material use x2 test.It is statistically significant difference when p<0.05.Results:1. The statistics of IMT taken from Group One is obviously higher than those of Group two (P< 0.0001); there is also a clear distinction in the occurrence rates of atherosclerosis plaque between the two groups. (P<0.001)2. There is no noticeable difference between the two group in terms of carotid artery diameter (P>0.05).3. The atherosclerosis plaques in the two groups are equally scattered on both sides, with the occurrence rate on each part of the carotid arteries as such: BIF> CCA> ICA> ECA. (P>0.05)4. Occurrence rates of different plaques in the two groups:the plaques of fibrous cap and fatty, the flat plaques of fatty sites are more common in Group One, while the flat plaques of fatty sites,the calcified plaques are more likely to be found in Group Two.5. VET can provide a much finer resolution for the microstructures of the carotid vascular wall and the plaques. VET also increases the definition on carotid arteries'IMT and the periphery of the plaques. Ultrasound and VET show an critical distinction in the definitions of plaque periphery, pathological cells'microstructure and IMT lumen(P<0.01). Conclusions:Hyperlipidemia is a risk factor of atherosclerosis. With largely enhanced display capability and display sensitivity, High-frequency ultrasound and VET. can produce much clearer images of the vessel lumen and its wall structure. Therefore, they have a comparatively high clinical value. Through dynamic observations, the degree of atherosclerosis in a hyperlipidemia case can be properly assessed, as well as whether there is a plaque or a clogged lumen. Such information provides not only diagnostic indicators for atherosclerosis (cerebral infarction in particular), but early predictions of the atherosclerotic degree, thereby playing a important role in the early treatment and effective prevention of atherosclerosis.
