CTA胸部三联检查在急诊胸痛患者诊断中的应用分析

Application of Chest CTA Triple Examination in the Diagnosis of Emergency Chest Pain

目的研究CT血管成像(CTA)胸部三联检查在急诊胸痛患者诊断中的应用价值。方法回顾性分析本院2019年1月至12月诊治的52例急诊胸痛患者临床资料,均在本院接受CTA胸部三联检查,另选取同期根据病史和临床表现需行单纯冠状动脉CTA(CCTA)检查患者45例,作为对照组。评估研究组患者检查结果,并比较两组患者平均扫描图像质量、扫描部位辐射剂量和扫描参数。结果共检出冠状动脉狭窄16例,肺动脉栓塞12例,胸主动脉夹层5例,其他疾病11例,另8例患者未见明显异常;两组冠状动脉图像质量比较无统计学意义(P<0.05);研究组患者扫描长度(SL)、剂量长度乘积(DLP),并计算有效剂量(ED)均显著高于对照组(P<0.05);两组患者心率比较无统计学意义(P>0.05),但研究组患者扫描时间以及总检查时间均高于对照组(P<0.05)。结论CTA胸部三联检查应用于急性胸痛中可快速鉴别诊断患者疾病,具有图像质量优等特点,具有较高的临床应用价值。

Objective To study the application value of chest CT angiography(CTA)triple examination in the diagnosis of emergency chest pain.Methods The clinical data of 52 patients with emergency chest pain diagnosed and treated in the hospital between January and December,2019 were retrospectively analyzed.All of them completed chest CTA triple examination.Meanwhile,45 patients who needed to be examined with simple coronary artery CTA(CCTA)were selected as the control group,based on medical history and clinical manifestations.Examination results of patients in the study group were evaluated,and image quality,radiation dose and scan parameters of the two groups were compared.Results A total of 16 cases with coronary artery stenosis,12 cases with pulmonary artery embolism,5 cases with thoracic aortic dissection and 11 cases with other diseases were detected.The remaining 8 patients showed no obvious abnormalities.Coronary artery image quality showed no statistically significant difference between the two groups(P<0.05).The scan length(SL),dose-length product(DLP)and effective dose(ED)of the study group were significantly larger than those of the control group(P<0.05);but there was no statistically significant difference in heart rate between the two groups(P>0.05).The scanning time and total examination time of the study group were longer than those of the control group(P<0.05).Conclusion Chest CTA triple examination can be used to quickly diagnose patients with acute chest pain,which can obtain excellent image quality.
