Introduction and Background The introduction of thoracic stent grafts into clinical practice over the past two decades and the ability to image the thoracic aorta in high definition have offered a paradigm shift in the way we have been able…
Introduction Bolton Medical (Sunrise, Florida), now owned by Terumo (Tokyo, Japan), introduced the Relay thoracic endovascular aortic repair (TEVAR) endograft in 2005, with Phase II trials for approval in the United States beginning in 2007. In 2009, RelayPlus was introduced,…
Introduction Since the advent of endovascular abdominal aortic aneurysm repair (EVAR) for abdominal aortic aneurysms (AAA), the rate of technical proficiency has reached impressive levels, with modern reports reaching 99%–100% of endografts successfully placed during initial treatment. However, despite technical…
Introduction The Conformable TAG (CTAG) endoprosthesis (WL Gore and Associates, Flagstaff, Arizona) is the third-generation thoracic endograft approved for treatment of aneurysm, traumatic transection, and Type B dissection in the descending thoracic aorta. The second-generation TAG endoprosthesis was the first…
Introduction Thoracic endovascular aortic repair (TEVAR), first performed in 1992, has become the treatment of choice for the majority of thoracic aortic pathologies, including thoracic aortic aneurysms (TAAs) and complicated Type B aortic dissections (TADs). Presence of an endoleak is…
Endovascular repair of thoracoabdominal aortic aneurysms requires long segment stent graft coverage with concomitant revascularization of the renovisceral and potentially supraaortic arch segments. Such procedures represent the highest extent of complex endovascular therapy and are associated with increased technical demand,…
Overview Endoleaks, or persistent flow into the aneurysm sac, are the most common complication of EVAR, occurring in up to a third of cases. They occur at the time of graft implantation, or arise during followup, with varying implications. The…

Points of Attention in Branched EVAR Branched endovascular aortic aneurysm repair (B-EVAR) was developed for the treatment of thoracoabdominal aortic aneurysms (TAAA). With increasing physician experience and device evolution we can at the moment treat almost all types of aneurysms…
Stent Graft Design Many of the complications of endovascular aneurysm repair result from a mismatch between the demands of the pathology and the capabilities of the device, and many can be avoided by proper patient selection and device selection, based…
