Is abdominal aortic aneurysm the same thing as aortic dissection?

In brief: AAA v dissection

Not really; an aneurysm bulges due to a weakness in the artery wall.
A dissection is a tear in one or more ( of the three) layers of the artery wall which continues in one or both directions.

In brief: No

Can happen together on occasion.
Usually AAA does not "dissect" which is an intramural tear and hematoma. Other non aneurysmal vessels may tear with hypertension or degenerative vessel wall.

In brief: No.

Dissections may become aneurysmal.
An abdominal aortic aneurysm is a full thickness dilatation of the aortic wall. In a dissection, there is a tear of the intima and the blood then shears the layers appart crating either 2 lumens or a mural hematoma or both.
