Severe infrarenal aortic neck angulation alone may not be a predictor of adverse outcomes in the medium term following endovascular aortic aneurysm repair

Abstract

Endovascular repair is widely used as an alternative to open repair for abdominal aortic aneurysm (AAA ) as the choice of treatment, owing to reduced perioperative morbidity and mortality, and shorter hospital stay.1 However, delayed complications and need for reinterventions during the follow-up period have cast a shadow over its efficacy.2 Severe infrarenal aortic neck angulation (SNA) in patients undergoing endovascular aneurysm repair (EVAR ) has been associated with perigraft endoleak resulting from poor graft apposition, poor proximal seal, and graft separation.3 There is limited evidence on the prognostic role of SNA in EVAR . We aimed to examine outcomes in patients with SNA following EVAR while controlling for anatomical and clinical characteristic
