Which DeBakey type describes a dissection confined to the ascending aorta?

Explanation:
This question tests how DeBakey classification uses the origin and spread of an aortic dissection. A dissection that starts in the ascending aorta and stays confined there, not involving the aortic arch or the descending aorta, is DeBakey type II. If the tear begins in the ascending aorta and then propagates into the arch or beyond, it would be type I. If the dissection originates in the descending (distal) aorta and extends downward, that’s type III (often aligned with the term type B in some schemas). So, confined to the ascending aorta = DeBakey type II.
