The other statements are not accurate:
- A: Abdominal aortic aneurysm is not typically associated with renal artery stenosis (RAS) in 25% of cases. While renal artery stenosis can be present in some patients with abdominal aortic aneurysm, the association is not as prevalent as stated.
- C: Mycotic aneurysms can occur in various locations but are not most frequently associated with the ascending aorta. They can affect any part of the aorta but are more commonly seen in the abdominal aorta.
- E: Renal failure occurs in a significant proportion of postoperative patients with aortic aneurysm repair, but 14% may be an overestimate; rates can vary depending on the surgical approach and patient condition.
