Endovascular AAA Repair: Classification of Aneurysm Sac Volumetric Change Using Spiral Computed Tomographic Angiography

Abstract

This classification system of spiral CTA volumetric changes features 6 patterns with recognized clinical significance and predictive value for endoleaks. Group I is the ideal outcome when the aneurysm sac shrinks and often completely disappears, while group III is associated with types I and type III endoleak and should prompt further investigation. Long-term volumetric analysis of all patients is advised.
