Clinical Use Of Ultrasound Combined With Multidetector CT For Aortic Dissection

Objective:to evaluate the superiority of the combined modality examination in terms of diagnostic accuracy of dissection by comparing the three tests:ultrasound CT combined modality examination,ultrasound,and CT alone.Methods:97 hospitalized patients with aortic dissection aneurysms who were enrolled from January 2016 to September 2019 in the First Affiliated Hospital of Zhengzhou University were selected as subjects according to a retrospective analysis,The complete data of all patients were collated and collected,ultrasound,multidetector CT examination were given,respectively,and the imaging characteristics of all subjects were carefully observed,and the detection coincidence rate of single ultrasound,multidetector CT with the combined diagnosis of the two,At the same time,the true and false lumens,avulsed intimal sheets,intimal breaches,re breaches,regurgitation of the aortic valve,involvement of the aortic valve,and branches of the affected aorta were observed in the experimental subjects under different examination methods,To compare the detection rates of de Bakey types Ⅰ,Ⅱ,and Ⅲ when different examination methods were compared,to analyze the advantages of ultrasound combined with multidetector CT in the examination process,and to explore the value of ultrasound combined with multidetector CT in aortic dissection.Results:the detection concordance rate of 100.00%for combined modality examination was significantly higher(P<0.05)than that of 80.41%for single modality ultrasound and 93.81%for multidetector CT.Although there was no difference between the two examination methods in terms of the appearance of true and false lumens,avulsed intimal sheets,and re ruptures(P>0.05),ultrasound was more frequently performed in cases of multiple row spiral CT for intimal ruptures and affected aortic branches,but less frequently for aortic regurgitation and affected aortic valves(P<0.05).The detection rate was lower on the de Bakey types Ⅰ,Ⅱ,and Ⅲ with ultrasonographic first pass,multidetector row computed tomography(multidetector CT)than with combined modality testing,However,the detection rates on re-view multidetector CT,de-Bakey type Ⅰ,Ⅱ,and Ⅲ on re-view ultrasound were higher than on re-view sonography first pass,multidetector helical CT first pass(P<0.05.).Conclusion:ultrasound and multidetector CT alone have a high clinical diagnostic yield and typing accuracy,and the combination of ultrasound and multidetector CT is effective in improving the detection rate,while facilitating the examiner’s knowledge of the patient’s overall abnormalities and the differentiation of DeBakey classification,which can provide more detailed information to the surgeon,more early and accurate diagnosis,and the choice of subsequent treatment options and prognosis for the patientThe post evaluation provides a reference basis and has the value of clinical promotion and use.
