Growth rates of small abdominal aortic aneurysms assessed by computerised tomography: a systematic literature review

Background: Most current evidence examining abdominal aortic aneurysm (AAA) growth is based on ultrasound surveillance.\ud \ud Objective: This review aimed to systematically analyse studies which have assessed small AAA growth using computed tomography (CT) to monitor outcome.\ud \ud Method: Studies investigating small AAA expansion rates using CT images were identified by searching the PubMed database and hand searching article reference lists. Eligible studies must have focused on monitoring small AAA growth using CT and included patients with baseline AAA diameters
