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。
Objective To investigate the advantages of digital subtraction whole cerebral angiography (DSA) and B-ultrasound in detecting carotid atherosclerosis in ischemic cerebrovascular disease. Methods Eighty patients with ischemic cerebrovascular disease underwent DSA and B-ultrasound and compared the detection rate of carotid atherosclerosis. The correlation between the imaging findings and clinical manifestations was analyzed. Results There were 69 cases of extracranial carotid lesions detected in DSA (detection rate was 86.67%). There were 132 affected arteries, 75 carotid stenosis with plaque, 32 intracranial stenosis, 25 other extracranial artery stenosis, Arterial stenosis was higher than that of non-carotid artery stenosis. The distribution of stenosis in different involved arteries was stenosis grade 1, grade 52, grade 2, grade 41, grade 3, grade 26, grade 4, grade 13. Sixty-one cases of carotid stenosis (plaque) were detected by B-mode ultrasonography in 16 cases (76.7%), 16 cases of CCA, 35 cases of BIF and 20 cases of ICA. Twenty three cases were confirmed with luminal stenosis, 8 cases. Conclusion Carotid atherosclerosis plays an important role in the pathogenesis of ischemic cerebrovascular disease. DSA has an important value in the diagnosis of ischemic cerebrovascular disease. Compared with B-ultrasound, it has the advantages of extensive examination and exactness The advantages.
