The Aortoiliac Artery Bifurcation Angle May Be a New Indicator for Predicting the Growth of Abdominal Aortic Aneurysm

AIABA is an independent predictor of AAA growth.Clinical ImpactThe aortoiliac artery bifurcation angle is an independent predictor of abdominal aortic aneurysm progression. Abdominal aortic aneurysm with an aortoiliac artery bifurcation angle < 45° or > 90° are likely to grow faster. Abdominal aortic aneurysms surveillance strategies based on diameter could be modified, a risky angle (< 45° or > 90°) of bifurcation should be considered even if the maximal diameter of the AAA is within the conventional safe range.
