Abdominal Aortic Aneurysms : A New Endovascular Approach

A n abdominal aortic aneurysm (AAA) consists of a localized dilation of the aorta, with an increase in diameter of at least 50%. 1 Most AAAs are located in the infrarenal region. Their prevalence has increased 300% in the past 30 years (between 3% and 6% in men over 65 years of age and 10% in men over 70). The increased prevalence of this condition and the aging population have elevated the cost of treating AAAs. An aneurysm of the abdominal aorta can be treated either surgically or via a prosthetic endovascular implant. This article explains what endovascular treatment consists of and outlines its primary advantages and disadvantages.
