摘　　要：目的运用数字减影血管造影(digital subtraction angiography, DSA)技术,分析短暂性脑缺血发作患者脑部血管狭窄情况。方法方便选取2017年5月—2018年5月来该院就诊的100例短暂性脑缺血患者,采用数字减影血管造影技术;参照北美症状性颈动脉狭窄率的计算方式,计算脑部血管狭窄率;根据临床症状,对比分析颈内动脉系统(ICA)组68例和椎基底动脉系统(VBA)组32例在颅内外动脉狭窄及分布和血管狭窄率等指标。结果 DSA结果显示,脑血管狭窄阳性率为88%,包含狭窄处或闭塞的部位共有154个、ICA组窄处有109个、VBA组狭窄处有47个,经过比较分析,ICA组患者颅内大脑中动脉狭窄处42个,显著多于VBA组9个;颅外颈内动脉起始狭窄22个,显著多于VBA组2个,这两组患者在颅内动脉、颅外动脉的发生情况之间的比较差异有统计学意义(χ~2=11.2, 8.4; P<0.05)。颅内动脉的狭窄及闭塞比颅外动脉多,主要累及大脑中动脉和颈内动脉起始部位,其次为椎动脉开口处。结论 DSA可确定脑血管狭窄的部位、范围、程度,在血管狭窄率的诊断中发挥重要的作用,为临床诊断提供强有力证据,值得临床推广使用。Objective To analyze the cerebral vascular stenosis condition of patients with transient ischemic attack by the DAS technology. Methods 100 case of patients with transient ischemic attack diagnosed in our hospital from May 2017 to May 2018 were convenient selected, and used the DSA technology, and the cerebral vascular stenosis rate was calculated according to the calculation way of symptomatic carotid artery stenosis in North America, and the intracranial and extracranial artery stenosis, distribution and vascular stenosis rate in 68 cases in the ICA group and in 32 cases in VBA group were compared and analyzed. Results The DSA results showed that the positive rate of cerebrovascular stenosis was 88%, including 154 stenosis or occluded sites, 109 stenosis in the ICA group, 47 stenosis in the VBA group, and the comparison and analysis showed that there were 42 arterial stenosis of encephalic brains in ICA group, which were obviously more than 9 cases in the VBA group, and there were 22 extracranial internal carotid artery stenosis, which was obviously more than 2 cases in the VBA group, and the difference in the occurrence of intracranial and extracranial arteries between the two groups was statistically significant（χ^2=11.2, 8.4; P〈0.05）, and the stenosis and occlusion of intracranial artery were more than those of extracranial artery, mainly involved in original sites of middle cerebral artery and internal carotid artery, secondly vertebral artery opening. Conclusion The DAS can determine the site, range and degree of cerebrovascular stenosis, which plays an important role in the diagnosis of vascular stenosis rate, and it can provide powerful evidence for the clinical diagnosis, and it is worth clinical promotion and application.
