Aortic Diameter ≥5.5 cm Is Not a Good Predictor of Type A Aortic Dissection

Abstract

The majority of patients with acute type A acute aortic dissection present with aortic diameters <5.5 cm and thus do not fall within current guidelines for elective aneurysm surgery. Methods other than size measurement of the ascending aorta are needed to identify patients at risk for dissection.
