CT - Non-gated CTA
Axial non-contrast
Axial C+ arterial phase
Coronal C+ arterial phase
Sagittal C+ arterial phase
What is the main finding?
Stanford type A aortic dissection (involving the ascending aorta).
What other pertinent findings are there?
The dissection flap involves both common carotids, the coeliac axis and the SMA. The left kidney is largely supplied by the false lumen.
Dissection of the ascending and descending thoracic aorta, extending from the aortic root to just proximal to the aortic bifurcation.
Ectatic ascending aorta, and displacement of the calcified lumen apparent on the pre-contrast study.
The left coronary artery is supplied by the true lumen. Cardiac motion limits interpretation of the right coronary vessels.
Dissection flap extends into both common carotid arteries within the scanned extent. Both subclavian arteries appear normal.
The dissection extends into the coeliac and superior mesenteric arteries. The left kidney is mainly supplied by a vessel arising from the false lumen (although there is a small intimal defect and an accessory artery) and enhances less than the normal right kidney.
Normal iliacs.
