Discussion Within this study, we observed the instant hemodynamic impact upon the thoracic endovascular aortic repair by 4D phase-contrast MRI through the following parameters estimating accurate and false lumen of aortic dissection: stroke volume (SV), forward flow volume (FFV), backward flow volume (BFV), and regurgitant fraction (RF). To reduce interindividual variation, we compared the data within the identical individuals before and following TEVAR (Figures 2 and three). The SV was higher inside the correct lumen of patients with graft stents than in these with aortic dissection with out intervention, plus the RF, an indicator of nonlaminar f.
