缺血性脑血管病DSA与B超诊断对比 　　【摘要】 目的 探讨缺血性脑血管病数字减影全脑血管造影(DSA)与B超检测颈动脉粥样硬化的优势。方法 对80例缺血性脑血管病患者行DSA检查以及B超观察及对比评价颈动脉粥样硬化检出率的情况,分析影像结果与临床表现的相关性。结果 DSA检出颅外颈动脉病变者69例( 检出率86.67%),受累动脉132支,颈动脉狭窄伴斑块75支,颅内动脉狭窄32支,其他颅外动脉狭窄25支,颈动脉狭窄高于非颈动脉狭窄的发生率,不同受累动脉的狭窄程度分布:狭窄1级52支,2 级41 支,3 级26支,4级13支。B超检出颈动脉狭窄(斑块)61例(检出率76.7%),CCA16例,BIF35例,ICA20例,管腔确定为管腔狭窄23例,管腔明显狭窄30例,血管完全闭塞8例。结论 颈动脉粥样硬化病变在缺血性脑血管病的发生中起重要作用,利用DSA检查在缺血性脑血管病的诊断中有重要的应用价值,对比B超具有检查广泛性、确切性的优点。 　　【关键词】 缺血性脑血管病;动脉粥样硬化;DSA;B超 　　 　　The diagnosis comparison between DSA and B-US for ischemic cerebrovascular disease 　　 　　WANG Shang-jun, WANG Ji-liang, ZHAO Xiao-wei, DU Ping.

Methods 80 cases of patients with ischemic cerebrovascular disease were inspected by both the DSA and B-US and the detection rate of carotid atherosclerosis was evaluated in order to analyze the relativity between the imaging results and clinical performance.Results DSA detected 69 cases (detection rate86.67%)of extracranial carotid artery lesions,132 branches of affected artery, 75 branches of carotid artery stenosis plaque, 32 braches of intracranial arterial stenosis and other 25 cases of extracranial artery stenosis, the incidence of carotid artery stenosis was higher than that of non-carotid artery stenosis. The stenosis degree distribution of different affected artery: first-class stenosis52 braches, second-class 41 braches,third-class 26 braches,fourth-class 13 braches. B-US detected 61 cases of carotid artery stenosis (plaque) (detection rate 76.7%), CCA16 cases, BIF35 cases, ICA20 cases, 23 cases of luminal stenosis were identified as well as 30 cases of luminal stenosis and 8 cases of complete occlusion of blood vessels.Conclusions The lesions of carotid atherosclerosis plays an imp
