Influence of the Textile Structure on the Degradation of Explanted Aortic Endoprostheses

Abstract

It is essential to take into account the saturation index to optimally choose a woven textile for the construction of an endoprosthesis since this property of the textile may contribute to explain the macroscopic lesions observed. We did not observe significant polymer degradation by filament dynamometry but further studies are needed to confirm these data.

Virtual evaluation of stent graft deployment: A validated modeling and simulation study

“…In the long term however, the outcome does not differ significantly (Schermerhorn et al, 2008). One reason for this are stent graft related complications, including graft migration, endoleakage and fatigue failings (Chakfé et al, 2004;Jacobs et al, 2003;Zarins et al, 2004;Schlö sser et al, 2009;De Bruin et al, 2010).…”

Computational mechanics of Nitinol stent grafts

“…However, stent-graft failure, i.e., implant migration, device fatigue, and endoleaks resulting potentially in AAA rupture (see Kleinstreuer and Li, 2006), remains a major concern. Focusing on endovascular implants, they may experience metal fracture, fabric erosion, suture breakage, and ultimately device failure (Beebe et al, 2001;Jacobs et al, 2003;Zarins et al, 2004;Chakfe et al, 2004;among others).…”

Post-traumatic acute thoracic aortic injury (TAI)—a single center experience

“…The treatment of endovascular stent graft implantation is a relatively novel therapeutic method to treat TAI. According to our knowledge, there are currently no long-term studies with follow up period 10-15 years that could assess function of stent graft (25)(26)(27)(28). Surgical treatment of lesions of the ascending aorta include classical surgery from median sternotomy with the use of extracorporeal circulation and at least mild hypothermia while repair of descending aorta requires wide thoracotomy (14).…”

“…The conventional surgical methods of reconstruction of the descending part is still accompanied by very high operative risk (15,16). Alternative endovascular treatments (TEVAR), may enable to avoid surgical risk, particularly among patients with critical, risk factors and comorbidities (20)(21)(22)(23)(24)(25)(26)(27)(28)(29). The highest volume TEVAR comparison with open surgery in TAI cases was reported by Demetriades and colleagues.…”
