目的分析及比较在颈动脉狭窄的临床诊断中分别应用脑血管造影与血管超声的临床价值。方法收集本科室2013年10月-2016年10月间接收的患缺血性脑血管病变的180例患者,入院后均施行脑血管造影、血管超声等检查,详细收集2组患者的影像学检查资料,以比较两种检查方法的应用价值。结果两种检查方法在不同程度颈动脉狭窄上的检出率对比差异不显著(P>0.05)。而将患者的脑血管造影作为金标准进行分析发现,血管超声在无狭窄、轻度狭窄、中度狭窄、重度狭窄及闭塞等上的敏感性分别为94.74%、96.67%、79.41%、92.19%、100%,由此可见,血管超声在中度狭窄上的敏感性相对较低,差异存在统计学意义(P<0.05)。结论血管超声在颈动脉狭窄中的诊断价值较脑血管造影相对更为优秀,值得临床借鉴。
Objective To analyze and compare the clinical value of cerebral angiography and vascular ultrasound in the clinical diagnosis of carotid artery stenosis. Methods A total of 180 patients with ischemic cerebrovascular diseases received from the department between October 2013 and October 2016 were enrolled in this study. Cerebral angiography and vascular ultrasound were performed after admission. The imaging examination of 2 groups of patients was collected in detail. Data to compare the value of the two methods of inspection. Results There was no significant difference in the detection rate of carotid stenosis between the two methods (P> 0.05). The analysis of patients with cerebrovascular angiography as the gold standard found that the sensitivity of vascular ultrasound in the no stenosis, mild stenosis, moderate stenosis, severe stenosis and occlusion were 94.74%, 96.67%, 79.41%, 92.19% , 100%. Thus, the sensitivity of vascular ultrasound in moderate stenosis is relatively low, the difference was statistically significant (P <0.05). Conclusion The diagnostic value of vascular ultrasound in carotid artery stenosis is relatively better than that of cerebral angiography, which is worthy of clinical reference.
