The ascending aorta is dilated, measuring 37 mm at its widest point.
Stanford type B aortic dissection, originating from the height of the left CCA and involving a short segment of the left SA. The celiac trunk and the left RA are supplied by the false lumen and the origins of the CHA (arises separately from the celiac trunk) and SMA lie on the border between true and false lumina. The dissection terminates at the aortic bifurcation and so both CIAs are supplied by the true lumen.
