AAA stands for abdominal aortic aneurysm. The aorta is the main artery that carries blood from the heart, and the abdominal portion is the part that travels through the abdomen. When a segment of that vessel dilates, it forms an aneurysm, specifically in the abdominal portion, hence the term abdominal aortic aneurysm. The other options miss or misstate key details: simply “abdominal aneurysm” lacks the vessel name, “abdominal arterial aneurysm” uses a generic artery instead of the aorta, and “abdominal aortic dissection” describes a tear in the vessel wall rather than a dilation. So the standard and precise term is abdominal aortic aneurysm.
