An observational assessment of aortic deformation. Witheford et al.

Objective: Real-time aortic deformation during endovascular aortic aneurysm repair (EVAR) has not been reported. Successful EVAR relies on predicting intraoperative aortic-endograft deformation from preoperative imaging. Correct prediction is essential, because malalignment of endografts decreases patient survival. We describe intraoperative aortic deformation during infrarenal EVAR and complex fenestrated/branched EVAR (F/BEVAR), relating deformation to preoperative anatomy and follow-up outcomes.
