Aortic aneurysms usually do not cause any symptoms, but some patients do experience indications, such as severe chest, abdominal and back pain, shortness of breath or difficulty swallowing, according to WebMD. If the aneurysm ruptures, the patient can experience loss of consciousness, stroke or a heart attack.
Aortic aneurysms are often discovered while a patient receives medical care for an unrelated condition, the University of California in Los Angeles explains. Some signs that can lead to aortic aneurysm diagnosis include elevated blood pressure, pain following digestion, weight loss or urinary tract infection. Poor organ and lower extremities circulation is also an indicator. The cause of aortic aneurysms remains unknown, but cigarette smoking, high blood pressure and chronic pulmonary disease are risk factors.
