“…Sensitivity and specificity are both close to 100% when compared with operative findings. In about 1% to 3% of the time, the aorta cannot be visualized because of bowel gas or obesity (58)(59)(60). In general, ultrasound is an ideal test for mass screening (61).…”

Physicians must make decisions about screening patients for abdominal aortic aneurysms (AAAs), monitoring or referring for surgery patients with AAAs of various sizes, and assessing patients with symptoms that may be related to AAAs. This review article analyzes the evidence for each scenario. The effectiveness and cost-effectiveness of screening for AAA is based on results from four randomized controlled trials. A cost-effectiveness analysis using a Markov model showed that ultrasound screening of white men beginning at age 65 is both effective and cost-effective in preventing AAA-related death. Such screening would have a small but real impact over a 20-year period in these men. For patients with a known AAA-which is often detected incidentally-the evidence clearly suggests periodic ultrasound surveillance for those with small AAAs (3.0-3.9 cm in diameter) and elective surgical repair for those with large AAAs (>or=5.5 cm). Two recent randomized controlled trials have shown that early surgical repair confers no survival benefit compared with periodic surveillance for patients with intermediate-sized AAAs (4.0-5.5 cm in diameter), so those patients can also be monitored. Some centers choose to increase the frequency of monitoring to every 3 to 6 months when the AAA reaches 5.0 cm. Factors to consider in assessing symptomatic patients include the high risk of life-threatening conditions, the potential increased risk of death or poor outcome with delay in diagnosis, the limitations of ultrasound in identifying whether symptoms are due to known or suspected AAA, and the timely availability of computed tomography or other imaging tests. If available, computed tomography is preferred in patients with recent or severe symptoms, since it is better at detecting retroperitoneal hemorrhage and other complications and in providing preoperative definition of the anatomy.

“…Cross-table lateral plain radiographs were once the most widely used test to evaluate for AAA, but are not sufficiently accurate for a potentially catastrophic disease (11). Abdominal computed tomography (CT) is nearly 100% sensitive and specific and may also serve to identify alternative diagnoses.…”

“…Periaortic collections, intramural air, and soft tissue infiltration are other common radiographic findings [32,33]. Moreover, rapidly enlarging or rapidly evolving aneurysms are highly suggestive of infection [34][35][36][37].…”
