Inverse Correlation Between Calcium Accumulation and the Expansion Rate of Abdominal Aortic Aneurysms

Abstract

In AAA, a lower extent of calcification correlated with accelerated expansion. The calcification index of an AAA can be a useful predictor of its expansion rate. The study findings also support the theory that the mechanisms for progression in atherosclerosis with calcification and external expansion of an aneurysm are distinct.
