摘要
目的研究急性肺动脉栓塞(acute pulmonary embolism,APE)诊断中CT血管造影(CT angiography,CTA)的应用价值。方法选取2019年6月—2021年12月启东市人民医院收治的109例疑似APE患者为研究对象,均行CTA检查,以肺动脉造影结果作为金标准,将CTA检查结果与肺动脉造影结果进行对比。结果肺动脉造影检查结果显示,109例疑似患者中确诊APE 99例,其余10例患者为冠心病3例,肺动脉炎7例。CTA对急性肺动脉栓塞诊断准确度为96.33%(105/109),诊断灵敏度为96.97%(96/99),诊断特异度为90.00%(9/10),阳性预测值为98.97%(96/97),阴性预测值为75.00%(9/12);CTA检查结果与肺动脉造影诊断结果的一致性较好(Kappa=0.776);与VR比较,MPR对叶动脉、段及以下动脉栓子检出率及总检出率均更高,差异有统计学意义(P<0.05);与MIP比较,MPR对段及以下动脉栓子检出率及总检出率均更高,差异有统计学意义(P<0.05)。结论APE诊断中CTA的应用价值较高,可为临床诊治提供可靠依据。
Objective To study the application value of CT angiography(CTA)in the diagnosis of acute pulmonary artery embolism(APE).Methods 109 patients with suspected APE admitted to Qidong People's Hospital from June 2019 to December 2021 were selected for the study,and all of them underwent CTA examination,using pulmonary angiography results as the gold standard.The CTA examination results were compared with the pulmonary arteriography results.Results The results of pulmonary arteriography showed that the diagnosis of acute pulmonary embolism was confirmed in 99 of 109 patients,while the remaining 10 patients had coronary artery disease in 3 cases and pulmonary arteritis in 7.The diagnostic accuracy of CTA for acute pulmonary embolism was 96.33%(105/109),the diagnostic sensitivity was 96.97%(96/99),and the diagnostic specificity was 90.00%(9/10).The positive predictive value was 98.97%(96/97)and the negative predictive value was 75.00%(9/12).Good agreement between the CTA findings and the diagnostic findings of pulmonary arteriography(Kappa=0.776).Compared with VR,MPR had a higher rate of detection and overall detection of emboli in lobar arteries,segments and below,the difference was statistically significant(P<0.05).Compared with MIP,MPR had a higher rate of detection of segmental and subsegmental arterial emboli and a higher overall detection rate,the difference was statistically significant(P<0.05).Conclusion The application of CTA in the diagnosis of APE is of high value and can provide a reliable basis for clinical diagnosis and treatment.
