Explanting the Nellix Endovascular Aortic Sealing Endoprosthesis for Proximal Aortic Neck Failure

Annals of Vascular Surgery
Cheong Jun Lee, Robert Cuff

Abstract

Open conversion after endovascular aortic repair has inherent challenges particular to the device being explanted. The Nellix endograft is unlike any other device as it uses polymer filling of endobags within the aorto-iliac lumen to seal the abdominal aortic aneurysm (AAA) sac, a developing concept known as endovascular aneurysm sealing. Conversion to open repair of AAA treated with the Nellix endograft has rarely been discussed. Explants that have been previously reported were for graft infection. We present 2 Nellix graft explants that were required for device migration and subsequent development of a type IA endoleak. The technique and nuances observed during open conversion of this novel endograft for proximal aortic neck failure is described in this report.

Cell Migration

Cell migration is involved in a variety of physiological and pathological processes such as embryonic development, cancer metastasis, blood vessel formation and remoulding, tissue regeneration, immune surveillance and inflammation. Here is the latest research.

Aortic Aneurysm

An aortic aneurysm is the weakening and bulging of the blood vessel wall in the aorta. This causes dilatation of the aorta, which is usually asymptomatic but carries the risk of rupture and hemorrhage. Find the latest research on aortic aneurysms here.

Aneurysm

Aneurysms are outward distensions or bulges that occurs in a weakened wall of blood vessels. Discover the latest research on aneurysms here.
