Stanford Type A dissection includes involvement of the ascending aorta. Which option best reflects this?

Explanation:
In aortic dissection classification, involvement of the ascending aorta defines Stanford Type A. If the ascending aorta is involved, it is categorized as Type A, regardless of whether the dissection also extends into the arch or descending aorta. In contrast, involvement limited to the descending aorta is Stanford Type B. DeBakey Type III is descending-only (maps to Stanford Type B), while DeBakey Type I or II involve the ascending aorta (and possibly other segments) and would also be considered Stanford Type A. So, when the stem notes ascending aorta involvement, the correct label is Stanford Type A.
