目的：：探讨颈动脉超声在腔隙性脑梗死疾病中的应用意义。方法：对本院2014年1月—2014年6月共55例经临床 CT确诊为腔隙性脑梗死的患者行颈动脉超声检查,分析其检查结果,55例患者中,男25例、女30例。结果：55例腔隙性脑梗死患者的颈动脉超声结果为发现颈动脉斑块45例,其中男性21例(21/25),女性24例(24/30),双侧颈动脉斑块22例、单侧颈动脉斑块23例；混合回声型斑块26例、强回声型斑块9例、低回声型斑块10例；规则斑块9例、不规则斑块36例。结论：颈动脉超声检查可作为腔隙性脑梗死患者重要的检查手段,且颈动脉超声能够准确提供颈动脉斑块的大小、形态等物理特性,对临床诊治及预后评估有着重要意义。“,”Objective Study on carotid artery ultrasound in patients with lacunar cerebral infarction disease application of significance.Methods On January 2014 ~2014-year in June,a total of 55 cases in the hospital by clinical CT diagnosis of cerebral lacunar infarction in patients with carotid artery ultrasonography,analyze its findings,in 49 patients,25 male and female in30 cases.Results 55 cases of lacunar cerebral infarction with carotid ultrasound results found that carotid artery plaques in 45 cases,21 males (21/25),24 female (24/30),bilateral carotid artery plaque in 22 cases,22 ca-ses of unilateral carotid artery plaque;mixed echo plaque 26 cases of plaque 9,acoustic,hypoechoic patch 10;regular patch 9 cases,irregular plaques in 36 patients.Conclusion Carotid artery ultrasonography can be used as important means of checking in patients with lacunar cerebral infarction and ca-rotid artery plaques in carotid ultrasound can provide the exact size,shape,physical characteristics,have important significance for clinical diagnosis, treatment and prognosis.
