Stent-Graft Migration following Endovascular Repair of Aneurysms with Large Proximal Necks: Anatomical Risk Factors and Long-term Sequelae

Abstract

Endovascular repair is successful in patients with large infrarenal necks and complex neck morphology. Changes in aneurysm remodeling over time were similar to reported observations in patients with more favorable neck criteria. Although no anatomical factor associated with migration could be identified from this analysis, distal displacement >1 cm correlated with the need for a secondary intervention.
