Is Assessment of Popliteal Artery Diameter in Patients Undergoing Screening for Abdominal Aortic Aneurysms a Worthwhile Procedure

This study has shown that, using conventional definitions, the imaging of popliteal arteries during screening for AAAs does not detect any popliteal aneurysms and is thus of limited value. However, if a definition of popliteal aneurysm of ≥1 cm (based on mean+2 SD) is used then 39/898 (4.3%) of arteries would be regarded as having abnormal diameters and may require surveillance.
