However, based on one systematic review and meta-analysis, POCUS has a sensitivity of 97.8% and a specificity of 97% for diagnosing AAA in patients supsected of having a ruptured AAA. </p> <p> Remeber:</p> <ul> <li> The normal abdominal aorta should measure under 3 cm.</li> <li> The proximal iliacs should measure under 1.5 cm. </li> <li> Measure the aortic diameter from leading edge to leading edge. </li> </ul> <p> Laslty, make sure you are measuring the aortic wall and not a mural thrombus. </p> <p> <img alt="" src="https://umem.org/files/uploads/content/pearls/Alexis/AAA.png" style="width: 550px; height: 367px;" /></p> <p> </p> <p> </p> <fieldset><legend>References</legend>
