Figure 1:

Centre line reconstructions of preoperative CT scan with contrast medium. (A) Patient 4: the maximum diameter of the dissected aorta was measured including true and false lumens, outer to outer aortic wall diameter, on axial transverse images perpendicular to the central line. (B) Patient 37: measure of the length of the ascending aorta. The ascending aorta begins at the plane corresponding to the sinotubular junction (white line 1) and extends to the plane immediately proximal to the origin of the brachiocephalic artery (red line 2): 88.5 mm corresponds to the length of the dissected ascending aorta.
