Background: Stanford A-type aortic dissection is one of the greatest risks of cardiovascular surgical diseases. How to actively and effectively treat this disease and reduce the mortality has been a problem in cardiovascular surgery. Purpose: To investigate the guiding values of modified retrospective ECG-gating (MR ECG-gating) towards the surgical method selection for Stanford A2-and A3-type aortic dissection. Methods: 10 patients with Stanford A2-and A3-type aortic dissection identified by the aortic CT angiography (CTA) were enrolled in this study. MR ECG-gating scanning was performed in 8 patients and the conventional scanning was performed on other 2 patients. The scanning parameters of intelligent collaboration technology (iCT) and performance of CTA were analyzed. Results: The contrast agent filling of arterial lumen of 8 patients who were performed with MR ECG-gating scanning was good, which could not only be accurately qualified, but also be used to accurately determine the positions of true/false double lumen and intimal rupture, as well as the damage situations of aortic valve. The contrast agent filling of arterial lumen of 2 patients who were performed with conventional aortic CTA scanning was poor, which could only exhibit the existence of aortic dissection, while could not accurately determine the positions of true/false double lumen and intimal rupture. Conclusion: MR ECG-gating CTA scanning can clearly exhibit the rupture location and size of Stanford A2-and A3-type aortic dissection, thus having certain guiding value towards the surgical method selection.
