Dear Cody,
An abdominal CT scan is probably the best way to characterize an abdominal aortic aneurysm. In a low risk person elective surgery should be considered when the aneursym is >4.0cm in diameter. Elective repair is definitely indicated when the aneurysm is between 4.5cm and 5cm. If a person does not quite meet the criteria for surgery they should be followed and have their blood pressure aggressively treated. A person should undergo regular follow-up CT scans to measure the progression of the aneurysm approximately every 6 months. There are intravascular stents available for people with aortic aneurysms but they are being done at few centers in select patients.
For more information I would recommend scheduling an appointment with a vasuclar surgeon at a large university based medical center. You can also visit our website at www.ccf.org or call for an appointment at 1-800-CCF-CARE. Hope this answers your question.
Thanks for your question,
