CTA,Ultrasound Combined with D-dimer in the Diagnosis of Stanford Type A Aortic Dissection and Its Staging
Objective To investigate the application of computed tomography angiography(CTA)and ultrasound combined with D-dimer(D-D)in the diagnosis of Stanford type A aortic dissection and its staging.Methods The clinical data of 98 patients with suspected Stanford A aortic dissection admitted to our hospital from March 2017 to March 2024 were retrospectively analyzed,and all of them underwent ultrasonography,CTA examination,and measurement of peripheral blood D-D level,and surgical results were used as the gold standard.The results of Stanford A aortic dissection detection under ultrasonography and CTA were counted and compared among all study subjects.Compare the plasma D-D level of Stanford A aortic dissection patients,non-Stanford A aortic dissection people and plot the working characteristic curve(ROC)of the subjects to analyze the diagnostic value.Analyze the detection results and diagnostic value of the combination of the three for Stanford type A aortic dissection.To analyze the detection results of ultrasonography,CTA examination,and plasma D-D measurement on the classification of Stanford type A aortic dissection,and to analyze the pictures of typical cases.Results The surgical results illustrated that 42 of 98 patients with suspected Stanford A aortic dissection were confirmed,and the remaining 56 were non-Stanford A aortic dissection patients,35 were confirmed by ultrasound,37 were confirmed by CTA examination,and plasma D-D levels were higher in patients with Stanford A aortic dissection than in non-Stanford A aortic dissection patients.Further analysis of the detection results and diagnostic value of the combination of the three on Stanford A type aortic dissection found that the diagnosis was confirmed in 39 cases,and the Kappa value compared with the surgical results was 0.757(P＜0.05).In addition,there was no statistically significant difference in the detection results of Stanford A type aortic dissection staging between the three alone and in combination(P＞0.05).Conclusion Ultrasound,CTA,plasma D-D joint diagnosis of Stanford A type aortic dissection results are better than the three alone,and the diagnostic value is higher,can be used as an auxiliary diagnosis of the disease main reference basis.
