【摘要】 目的探讨经颈二维B型超声观察缺血性脑卒中患者主动脉弓粥样硬化(AAA)与缺血性脑卒中的相关性及临床应用价值。方法采用经颈二维B型超声对2001年1月至2003年5月我科确诊的56例缺血性脑卒中患者的主动脉弓及颈动脉进行检测,同时对所有患者进行头颅CT或MRI检查。结果56例患者中33例(58.93%)发现AAA,46例(82.1%)发现颈动脉粥样硬化病变,同时合并AAA及颈动脉粥样硬化的32例(57.14%)。AAA的患者中脑梗死25例(44.64%),腔隙性脑梗死8例(14.29%),P<0.05;与缺血性脑血管病部分危险因素中年龄、性别、血糖、LDL的关系比较:AAA程度分级Ⅰ、Ⅱ、Ⅲ级,年龄、血糖、LDL呈增高趋势;性别比较,男性AAA阳性度高于女性,P<0.05;AAA与无AAA患者血糖比较,前者高于后者,P<0.05。结论AAA与缺血性脑卒中的危险因素密切相关,是缺血性脑卒中潜在的栓子来源和独立的危险因素。经颈二维B型超声探查56例缺血性脑卒中患者AAA的阳性率为58.9%,可以清楚地显示AAA斑块的形态学特征。该方法简便易操作且患者无痛苦,可广泛应用于临床,适合寻找病因不明的缺血性脑卒中患者潜在的栓子来源,指导服用调脂、抗凝及抗血小板药物的治疗,防止缺血性中风的复发,也适合应用于AAA的流行病学调查,并为缺血性脑血管病预防和治疗方案提供客观检查依据。更多还原

【Abstract】 Objective To study the correlation between the aortic arch atherosclerosis (AAA) and ischemic stroke,and clinical application value of Transcutaneous B-Mode Ultrasonography. Methods By using Transcutaneous 2-D B-Mode Ultrasonography, we examined the aortic arch and carotid artery,and by applying CT or MRI for skulls of the 56 paticnts, suffcring from ischemic stroke diagnoscd by our department from January,2001 to May,2003.Results Of the 56 patients,33(58.93%) had AAA,46(82.1%) had carotid artery atheromatosis,3(57.14%) had the both problems mentioned above.25 of the patients suffering from AAA had cerebral infarcts,and 8 had lacunar infarcts,P<0.05.With the increasing seriousness of AAA level Ⅰ Ⅱ Ⅲ,the patients’ age?blood sugar and LDL increased as well.The affirmative rate of AAA for male patients was higher than that of patients without AAA,P<0.05.Conclusion AAA is closely related to the risk factor of the ischemic stroed. By using Transcervical 2-D B-Mode Ultrasonography ,we have found that the morphology chatacteristic of AAA for the ischemic stroke is 58.9%.The method is simple and no complaints.With a big clinical application value,it can be used to find the potential emboli source in ischemic stroke patients with unknown etiological factors,assist the treatment with medication of decreasing hyperlipemia,resisting blood coagulatlon and platelet and prevent the relapse of ischemic stroke. It is also suitable for the epidemiology survey of AAA and can provide objective proof for examination of the prevention and treatment of ischemic stroke.更多还原
