摘　　要：目的探讨超声声学密度检测技术,Acoustic Densitometry(AD)定量评价颈动脉斑块稳定性的临床价值。方法将89例在我院住院的新发脑梗死患者分为两组,对照组42例给予常规治疗,实验组47例在常规治疗基础上给予普罗布考口服治疗,两组均以FHILIPS IU22型超声诊断仪检查。结果 6个月后复查,正常内膜AⅡc%有增加趋势,但差异无统计学意义。治疗组各型斑块AⅡc%较治疗前增大,且AⅡc%变化率与对照组差异有统计学意义。结论阿司匹林加普罗布考通过不同的机制在一定程度上可以增加各型斑块的声学密度;超声声学密度检测技术可以定量区分不同组织类型的粥样斑块,随访治疗前后斑块的组织学构成的动态变化,为临床诊断和治疗提供有价值的依据。Objective To investigate the clinical significance of Densitometry Acoustic（AD）in the quantitative evaluation of carotid plaque stability. Methods89 patients hospitalized in our hospital in the new cerebral infarction patients were divided into two groups,control group 42 cases were given conventional treatment,the experimental group of 47 cases on the basis of conventional treatment to give Probucol for treatment. Both groups used FHILIPS IU22 type ultrasonic diagnosis instrument for examination. Results After 6 months,the AII c% in normal intima had an increasing trend,but no statistical significance. In the treatment group,the AII c% of each type was significantly increased,and the change rate of A II c% was significantly different from that of the control group. Conclusion Aspirin and Probucol by different mechanisms in a certain extent can increase the acoustic density of various types of plaques. Acoustic densitometry detection technology can quantitatively distinguish different tissue types of atherosclerotic plaque,the dynamic changes of follow-up treatment before and after plaque histological structure and for clinical diagnosis and treatment provide valuable basis.
