AAA diameter at last ultrasound stratifies rupture risk; supports size-based thresholds but leaves open prospective validation.
Does the size of an abdominal aortic aneurysm at the last ultrasound predict rupture risk and growth rate in patients with AAA?
The risk of abdominal aortic aneurysm rupture is best estimated by the size at the most recent ultrasound, with risk increasing significantly at sizes ≥5.00 cm.
William W. Reed (1997) studied this question.
