Analysis of EndoAnchors for endovascular aneurysm repair by indications for use

Abstract

EndoAnchor implantation can be a useful adjunct to EVAR as prophylaxis against proximal attachment site complications in patients with hostile aortic neck anatomy, as treatment for early and late type Ia endoleaks, or, in conjunction with aortic extension cuffs, for endograft migration. Whereas the most challenging patients are those who present with type Ia endoleaks remote from initial EVAR, EndoAnchors are still effective in treating the majority of these cases.

Endoanchors under 3D image fusion for a type IA endoleak after EVAR

“…This system is a helical endovascular suture device intended to provide fixation of an endograft to the aortic wall. According to the instructions for use from the manufacturer, each helically shaped 4.5‐mm‐length, 3‐mm‐diameter EndoAnchor is implanted serially around the circumference of the endograft in the proximal aortic neck . After the identification of the leak channel, the procedure is completed creating an adjunctive “suture line” in correspondence of the leak.…”

Multispecialty involvement in the management of type B aortic dissections in the endovascular era-Implications for training cardiothoracic residents

“…The continued evolvement of endovascular technology, suggests a progression toward increased endovascular repair of the aorta. New devices are currently being developed specifically for the ascending aorta and aortic arch, and new technologies such as endoanchors are further extending the boundaries of currently available devices . This trend may account in part for the increased involvement of specialties with a more catheter‐based focus.…”

“…Endoanchors have been demonstrated to favorably augment the proximal seal zone associated with endovascular aneurysm repair (EVAR). 2,3 Their use in the infrarenal abdominal aorta has been divided between repair of a proximal Type I endoleak and prophylactic placement in patients who are thought to be at increased risk for graft migration. 3 Overall, procedural success has been reported to be 95% with endoanchors in the infrarenal abdominal aorta.…”
