Can anxiety attacks be caused by an aaa?

Anxiety/AAA. Not physically but the psychological strain can certainly lead to anxiety.
No. If you are asking if you should be concerned about a AAA if you are having anxiety attacks, then the answer is no. Screening is typically only done in men >65 yrs who have ever smoked or women >65 who have a family of aaas and also have ever smoked.
No. No, but a lot of people have anxiety over having an aaa. Talk to your doctor. See a board certified vascular surgeon to discuss the risks an benefits of surgery. With the modern techniques that we are currently employing to repair aneurysms the risk of surgery is very low.
