心电门控CTA评价急性主动脉夹层的临床应用研究
Clinical Application of ECG Gated CTA in Evaluation of Acute Aortic Dissection
摘要
Abstract
Objective: In this study, we would compare to the routine aorta CTA and ECG gated aorta CTA image quality, in order to know the advantage of ECG gated aorta CTA in evaluation of aortic dissection. Methods:Through the imaging system retrospectively selected 62 patients who underwent aorta CTA from 2013 January to 2016 March, divided into two groups. Group A underwent triple rule out scanning (13 cases), group B underwent aortic CTA (49 cases). Evaluation of aortic image quality and assessment of various indexes of aortic dissection. The measurement data were compared by two independent samplesttest, and count data were compared using chi-square test. A(P<0.05)consider the statistical significance difference. Results: Attenuation of aortic root in Group A was 367.000HU±28.73HU, in Group B was335.24HU±45.73HU(t=1.653,P=0.104), the difference was not statistically significant. The position and number of break,the aorta valve morphology, coronary artery morphology of group A and group B can be assessed statistically significant difference (P<0.05). intima morphology, branches of the aortic arch and true/false lumen could assessment showed no statistical significance (P>0.05). Conclusions: Applying the ECG gated aortic CTA compared with the conventional spiral aorta CTA, it could clearly displaythe index of aortic dissection, evaluate prognosis ofaortic dissection, guide the therapy and formulate operation /endovascular treatment plan.关键词
