Time-Related Alterations in Shape, Position, and Structure of Self-Expanding, Modular Aortic Stent-Grafts: A 4-year Single-Center Follow-up

Abstract

Tortuosity of the native vessels is a source of complication in long-term follow-up just as it is during implantation. Given the late appearance of complications in this patient cohort, it would seem that the durability of an endograft cannot be evaluated with < 3 years of follow-up.
