Morphovolumetric analysis of aneurysm sac and correlation with maximum diameter for post-EVAR surveillance

Post-EVAR morphological changes include reduced infrarenal aortic lengthening and neck dilatation. Lifelong surveillance is imperative after EVAR. The most effective method of organizing these surveillance protocols may involve a combination of Dmax and volume analysis, allowing for the most economical and reliable monitoring. Dmax is currently the fastest and most reliable data in post-EVAR surveillance. However, following our current study, we observed that relying solely on Dmax can be deceptive and should be correlated with volume analysis data.
