摘　　要：目的:探讨CT平扫、胸腹部CT血管造影检查在主动脉夹层患者诊断中的应用。方法:选取2020年5月~2021年5月本院收治的60例疑似主动脉夹层患者为研究对象,患者在入院后接受CT平扫、胸腹部CT血管造影检查。以急诊手术结果或主动脉造影检查结果为“金标准”,分析两种检查方法的灵敏度、特异度、符合率;对比两种检查方式图像质量、伪影情况、分型诊断情况,真假腔、破裂口判断情况。结果:急诊手术或主动脉血管造影检查结果证实AD的35例,其余25例患者为其他疾病。CT平扫诊断结果显示AD诊断正确的患者22例,非AD诊断正确的患者21例,灵敏度62.86%(22/35),特异度84.00%(21/25),符合率71.67%(43/60)。胸腹部CTA诊断结果显示AD诊断正确的患者32例,非AD诊断正确的患者25例,灵敏度91.43%(32/35),特异度100.00%(25/25),符合率95.00%(57/60)。胸腹部CTA的灵敏度、特异度、符合率均显著高于CT平扫,对比差异显著(P<0.05)。结论:胸腹部CT血管造影在主动脉夹层的诊断中诊断效能好,有较好的图像质量,帮助患者及早检出疾病,为患者的治疗赢得宝贵时机。胸腹部CTA对评估疾病分型,判断真假腔、破裂口均有极高的意义,对AD患者结局改善有极大的作用。Objective:To investigate the application of CT plain scan and thoracic and abdominal CT angiography in the diagnosis of patients with aortic dissection.Methods:60 patients with suspected aortic dissection admitted from May 2020 to May 2021 were selected for plain CT scan and thoracic and abdominal CT angiography after admission.Taking the results of emergency surgery or aortic angiography examination as the“gold standard”,analyze the sensitivity,specificity and coincidence rate of the two examination methods,compare the image quality and artifacts of the two examination methods,classification and diagnosis,and the judgment of true and false cavity and rupture mouth.Results:35 patients of emergency surgery or aortic angiography confirmed AD,while the remaining 25 patients had other diseases.CT scan showed 22 patients with correct AD diagnosis and 21 patients with correct non-AD diagnosis,with sensitivity 62.86%(22/35),specificity 84.00%(21/25),and compliance rate 71.67%(43/60).32 patients with correct AD diagnosis and 25 patients with correct non-AD diagnosis,sensitivity 91.43%(32/35),specificity 100.00%(25/25),and compliance rate 95.00%(57/60).The sensitivity,specificity,and compliance rate of the thoracic and abdominal CTA were significantly higher than that of the control group,and the contrast difference was significant(P<0.05).Conclusion:CT angiography of chest and abdomen has good diagnostic efficiency and good image quality in the diagnosis of aortic dissection,which helps patients to detect the disease as soon as possible and wins valuable opportunity for the treatment of patients.Thoracoabdominal CTA is of great significance for the evaluation of disease classification,the judgment of false cavity and ruptured mouth,and has a great effect on the outcome of AD patients.
