目的探讨螺旋CT血管造影 (SCTA)应用于急性脑梗死患者颈动脉系 统检查中的临床价值。方法 选取从2015 年10月至2016年10月在就诊于我院的急 性脑梗死患者50例进行分析。在治疗 前，对所有患者进行数字减影血管造影 (DSA)、颈部血管超声(CVUS)以及SCTA， 并且以DSA结果作为参照标准，对比经 CVUS和SCTA检查的颈动脉狭窄检出率、 颈动脉狭窄率、颈动脉狭窄程度以及颈 动脉斑块检出率，对SCTA检查做出评 价。结果 ①经SCTA和CVUS检查检出颈 动脉狭窄的检出率分别为52%和50%，差 异不具有统计学意义(P﹥0.05)；②SCTA 和CVUS检出的颈动脉狭窄率分别为 (32.98±10.92)%和(31.07±10.33)%， 两者差异并无统计学意义(P﹥0.05)；③ 经SCTA和CVUS检查检出颈动脉狭窄情况 的准确率分别为74%和46%，差异具有显 著的统计学意义(P﹤0.05)；④经SCTA和 CVUS检查检出颈动脉斑块检出率分别为 93.22%和73.73%，差异具有显著的统计 学意义(P﹤0.05)。结论 相比于同样是无 创的CVUS，螺旋CT血管造影(SCTA)在急 性脑梗死患者颈动脉系统检查中不仅能 更好地判断颈动脉狭窄情况，还能更好 地检出动脉斑块。

Objective To explore the clinical value of spiral CT angiography (SCTA) clinical value in acute cerebral infarction patients. Methods The data of patients with acute cerebral infarction who admitted to our hospital from October 2015 to October 2016 were analyzed. Before treatment, all patients underwent digital subtraction angiography (DSA), neck vascular ultrasound (CVUS) and SCTA. DSA results were used as the reference standard to compare the detection rate of carotid stenosis, the rate of carotid stenosis, the degree of carotid stenosis and the detection rate of carotid plaque between CVUS and SCTA examinations. Results The detection rates of carotid stenosis detected by SCTA and CVUS were 52% and 50% respectively, and the difference was not statistically significant (P>0.05). The rates of carotid stenosis detected by SCTA and CVUS were (32.98±10.92)% and (31.07±10.33)% respectively, and there was no significant difference between the two groups (P>0.05). The accuracy rate of carotid stenosis detected by SCTA and CVUS was 74% and 46% respectively, and the difference was statistically significant (P<0.05). The SCTA and CVUS detected the number of carotid plaques were 110 and 87 respectively, the plaque detection rates were 93.22% and 73.73% respectively, the difference was statistically significant (P<0.05). Conclusion Compared to the same noninvasive CVUS, SCTA can not only better assess the stenosis of carotid artery, but also detect the arterial plaque in patients with acute cerebral infarction better.
