Non invasive diagnostic methods like color scan duplex are gaining and important roll for vascular surgeons. With this method we can make an earlier diagnosis, especially in arterial pathology, lowering risk, costs and time for treatment. Because the ruptures of the aortic abdominal aneurism have a high mortality in patients of 80 years or more, it is important to detect this pathology and make its treatment before it ruptures. We show our experience in a pilot study with a veteran population from the Colombian Military Forces, during the month of May of the 2006. We demonstrate the utility of color duplex scanner for a screening test for the early detection abdominal aneurisms (without symptoms or signs) and we also demonstrate a high cost/benefi t ratio to lower morbility and mortality.
