【摘要】 目的:探讨超声背向散射积分(IBS)技术对高血脂患者早期动脉粥样硬化(atherosclerosis,AS)的诊断价值。方法:对98例中青年高血脂(高血脂组)患者和51例正常人(正常组)的颈动脉多部位多点进行IBS检测。结果:高血脂组颈动脉窦部(CSA)及颈内动脉(ICA)处C-IBS均低于正常组(P<0·05),高血脂组与正常组颈总动脉(CCA)处C-IBS比较差异无显著性(P>0·05)。高血脂组颈动脉不同部位即CSA与CCA、CSA与ICA处C-IBS比较差异均有显著性(P<0·05);正常组内CSA与CCA、CSA与ICA处C-IBS比较差异均无显著性(P>0·05)。结论:IBS技术可以反映血管壁的组织结构改变,为临床提供一种新的、无创性、简便易行的检测早期AS的方法。更多还原

【Abstract】 Objective To explore the diagnostic value of integrated backscatter (IBS) technique for carotid artery atherosclerosis (AS) in hyperlipemia patients.Methods The calibrated IBS (C-IBS, C-IBS=intima-media IBS-adventitia IBS) was used to detect the carotid intima-media in the different section in 51 normal controls and 98 patients with hyperlipemias. Results The C-IBS in hyperlipemia group was lower than that in normal control, there significant difference of C-IBS between carotid sinus artery( CSA) and internal carotid artery (ICA)(P<0.05), the C-IBS of common carotid artery(CCA) in hyperlipemia group was lower than that in normal control, but no significant differentce(P>0.05).In hyperlipemia group ,there were significant differences of C-IBS between CCA, CSA and ICA (P<0.05); and there were no significant differences of C-IBS between CSA and CCA, CSA and ICA (P>0.05). Conclusion IBS technigue can reflect the changes of tissue structure of vascular wall and provide a new ,no invasive and feasible method to evaluate AS early.更多还原
