颈部血管超声与CT血管造影联合诊断脑梗死患者颈动脉斑块的临床价值

Clinical Value of Combined Neck Vascular Ultrasound and CT Angiography in Diagnosing Carotid Plaque in Patients with Cerebral Infarction

目的分析脑梗死患者颈动脉斑块进行颈部血管超声、CT血管造影联合诊断的效果。方法选取2019年1月—2021年12月在山东大学第二医院诊治的66例疑似脑梗死的患者为研究对象,在数字减影血管造影检查下,诊断出颈动脉斑块者58例,患者分别接受CT血管造影检查与颈部血管超声检查,颈动脉斑块诊断的金标准为数字减影血管造影,比较CT血管造影检查与联合检查的诊断效能。结果颈部血管超声和CT血管造影联合诊断下的灵敏度、准确率分别为98.28%、95.45%,均高于单一CT血管造影诊断,差异有统计学意义(χ^(2)=15.508、13.963,P<0.001)。结论为脑梗死患者进行颈部血管超声结合CT血管造影诊断,具有较高的诊断准确率以及灵敏度,对于临床后续诊治十分有利,具有较高应用价值。

Objective Analysis of the combined diagnosis effect of cervical vascular ultrasound and CT angiography on carotid artery plaque in cerebral infarction patients.Methods Sixty-six patients with suspected cerebral infarction who were diagnosed and treated in the Second Hospital of Shandong University from January 2012 to December 2021 were selected as the research objects.58 patients were diagnosed with carotid artery plaque under digital subtraction angiography.The patients received CT angiography and cervical vascular ultrasound respectively.To compare the diagnostic efficacy of CT angiography and combined examination.Results Neck vascular ultrasound and CT angiography combined diagnostic sensitivity and accuracy were 98.28%,95.45%,respectively,were higher than single CT angiography in the diagnosis of,the difference was statistically significant(χ^(2)=15.508,13.963,P<0.001).Conclusion Cervical vascular ultrasound combined with CT angiography diagnosis for cerebral infarction patients has high diagnostic accuracy and sensitivity,which is very beneficial for clinical follow-up diagnosis and treatment,and has high application value.
