SCTA联合CVUS对急性脑梗死患者颈动脉狭窄及斑块检出率的影响

Effects of SCTA combined with CVUS on the detection rate of carotid artery stenosis and plaquein patients with acute cerebral infarction

目的探究螺旋CT血管造影（SCTA）联合颈部血管超声（CVUS）对急性脑梗死（ACI）患者颈动脉狭窄及斑块检出率的影响。方法选取ACI患者58例行SCTA、CVUS及数字减影血管造影（DSA）检查。以DSA检查结果为金标准，比较SCTA、CVUS单项检查与联合检查对颈动脉狭窄、斑块的检出情况。结果SCTA、CVUS联合检查颈动脉狭窄的检出率（93.10%）高于SCTA及CVUS单项检查（75.86%、70.69%），差异有统计学意义（P〈0.05）；SCTA、CVUS联合检查颈动脉狭窄程度综合准确率（93.10%）高于SCTA及CVUS单项检查（75.86%、68.97%），差异有统计学意义（P〈0.05）；SCTA、CVUS联合检查颈动脉斑块检出率（81.13%）高于SCTA及CVUS单项检查（64.15%、60.38%），差异有统计学意义（P〈0.05）。结论SCTA联合CVUS检查可进一步提高颈动脉狭窄、斑块检出率，为ACI诊断提供有力支持，在临床工作中值得推广应用。

Objective To investigate the influence of the spiral CT angiography （SCTA） com- bined with the cervical vascular ultrasound （CVUS） on the detection rate of carotid artery stenosis and plaque in patients with acute cerebral infarction （ACI）. Methods Fifty-eight ACI patients were select- ed as the research subjects, and all of them were examined by SCTA, CVUS and digital subtraction angi- ography （DSA）. The results of DSA were used as the gold standard to compare the detection rates of sin- gle detection and combined detection of SCTA and CVUS for carotid stenosis and plaque. Results The detection rate of SCTA and CVUS combined detection for carotid artery stenosis （93.10%） was higher than that of SCTA and CVUS （75.86%, 70.69% ）, respectively, the difference was significant （P 〈 0. 05）. The general accuracy rate of combined detection of SCTA and CVUS for carotid artery stenosis （93.10%） was higher than that of SCTA （75.86%） and CVUS （68.97%） single detection, the differ- ences were statistically significant （P 〈 0. 05 ）. The general accuracy rate of SCTA and CVUS combined detection for carotid stenosis （93.10%） was higher than that of SCTA and CVUS （75.86%, 68.97% ）, respectively, the differences were statistically significant （ P 〈 0.05 ）. The detection rate of SCTA and CVUS combined detection for carotid plaque （81.13%） was higher than that of SCTA （64. 15% ） and CUVS （60. 38% ）, the differences were statistically significant （P 〈0. 05）. Conclusions SCTA com- bined with CVUS can further improve the detection rate for carotid artery stenosis and plaque, and pro- vide a strong support for the diagnosis of ACI. It is worthy of promotion.
