Sometimes patients with an AAA will have some non-descript abdominal discomfort or pain, but usually these things are asymptomatic. When things become REALLY symptomatic, it's usually because the AAA has ruptured and this can be fatal. Because AAAs are common and many people are asymptomatic, in Canada, any man over the age of 50 who has longstanding high blood pressure will be screened with an abdominal ultrasound to make sure there is no aneurysm present.
