Aortic Neck Dilatation Following EVAR: Looking for a Needle in a Haystack

Abstract

Key to the long term success of an endovascular aneurysm repair (EVAR) is a durable proximal sealing zone. In their paper, Oliveira et al. provide a comprehensive investigation of aortic neck dilatation (AND) in a large single centre cohort of patients, who underwent standard infrarenal EVAR with self expanding stent grafts (SESs) over a 15 year period.1 While continued AND potentially poses a significant risk to this long term durability, there remain many unanswered questions, particularly in the context of SES.
