Potential Value of Aneurysm Sac Volume Measurements in Addition to Diameter Measurements After Endovascular Aneurysm Repair

Abstract

Volumetry detects sac size changes that are not reflected in diameter measurements. Vice versa, diameters can increase without a total volume increase, which might indicate a variety of morphological aneurysm changes. The agreement between volume and diameter measurements using different cutoff values is equally moderate. Volume measurements should be performed in addition to diameter measurements.
