Study on the Inaccuracy of Abdominal Aortic Aneurysm Measurements by Computed Tomography



November 18, 2004 -- A study on the inaccuracy of Abdominal Aortic Aneurysm (AAA) measurements by computed tomography will be presented in New York at VEITHsymposium, Sunday, November 21. There are implications regarding the misinterpretation of AAA growth and shrinkage concerning previous natural history studies.

Investigators behind the study say that most decisions regarding AAA therapy are based on an evaluation of absolute maximal diameter size or growth rate and that these measurements take on a heightened importance following endovascular repair, where the need for secondary interventions is often determined by maximal diameter measurements on serial computed tomography (CT) scans. It is the maximal diameter measurements from previous AAA natural history studies that relate aneurysm size and growth to rupture risk, and are used to guide the need and timing of operative therapy. Experts see a substantial difference when measuring repeatedly the same AAA on the same CT scan.&&&& &&&&

About VEITHsymposium: Now entering its fourth decade, VEITHsymposium has been the epicenter of physician education for the global vascular community. This international congress attracts over 1,500 thought leaders in the field. More than 250 international clinician/educators present the latest topics, advances and data and then validate these concepts through the dynamic interactive faculty/audience exchange that ends each session.

VEITHsymposium is sponsored by Montefiore Medical Center (Bronx, NY) with CME credit issued by Albert Einstein College of Medicine (Bronx, NY).
