Proximal Migration and Endoleak: Impact of Endograft Design and Deployment Techniques

One-year results of the ANCHOR trial of EndoAnchors for the prevention and treatment of aortic neck complications after endovascular aneurysm repair

“…3–7 Nevertheless, complications can and do develop at the proximal aortic neck, where adequate fixation and sealing must endure to prevent type Ia endoleak and endograft migration and thereby achieve long-term protection from aneurysm rupture. 8–10 The risk of failure at the infrarenal aortic neck is, in part, dependent on its anatomic configuration. Complications are most common when the neck is short, angulated, of large diameter, conical in configuration, or contains significant mural thrombus or calcium.…”

Midterm outcomes of the Zenith Renu AAA Ancillary Graft

“…[16][17][18] A critical complication unique to endovascular repair is the development of proximal attachment failure with subsequent development of migration and/or endoleak. 19 Migration has been shown to be a potential complication of all commercially available endografts. However, the AneuRx stent graft has typically been associated with higher migration rates than other devices.…”

Postoperative “Chimney” for Unintentional Renal Artery Occlusion after EVAR

“…EVAR-related renal artery occlusion is generally found intraoperatively following an EG maldeployment; however, it has been suggested that also those occlusions detected during the follow-up could be considered occluded since the initial operation [ 9 – 11 ]. Inan et al [ 12 ] described a case of intraoperative bilateral renal artery occlusion: the cause was a proximal migration of a bifurcated EG, an event that is anecdotal and mainly due to an iatrogenic upward thrust of the device during contralateralcannulation.…”
