The incidence of late open conversion is less than 5% following all endovascular aneurysm repairs. The endograft explantation is often necessary in patients with a persistent Type IA endoleak despite unsuccessful secondary interventions to correct the endoleak. The incidence of explant of an endograft is not related to the type of endograft used. Endograft failure within 1 year of implant is most commonly due to failure to achieve a satisfactory proximal seal at the index operation. Late failures are most commonly due to aneurysmal degeneration of the seal zones. The device material failure can also lead to Type I endoleak. The mortality of emergent explant can be as high as 40% and is usually less than 5% in an elective setting.
