The Bolton Treo endograft for treatment of abdominal aortic aneurysms: just another trimodular platform?

2018 
ABSTRACTIntroduction: The Treo abdominal aortic stent graft system (Bolton Medical, Barcelona, Spain) is a trimodular endovascular endoprosthesis recently introduced for the endovascular repair of abdominal aortic aneurysms (AAA). It presents some unique structural characteristics such as the combination of suprarenal and infrarenal fixation, variability of the main-body length, lock-stent mechanism in the iliac limbs to enhance their stability.Areas covered: This article discusses the technical features and clinical performance of Treo as well as the interesting hemodynamic consequences of its design.Expert commentary: The Treo aortic stent-graft provides accurate deployment, secure proximal seal and fixation as well as efficient conformability in angulated necks. Early results drawn from single-center studies are promising with acceptable technical and clinical success. Moreover, the custom-made solution provided with the Treo platform is one of the most intriguing challenges in current endovascular era...
