Mertens et al. (2011) looked at the long-term results of patients treated with the Zenith Flex stent graft. They analyzed 143 patients for overall survival, intervention-free survival, aneurysm rupture rates, early and late postoperative complications and endoleaks. At 5 years, 72.1% of patients and at 8 years 50.9% had survived. By 8 years 9% of patients (six total) had experienced a late aneurysm rupture, with three fatalities. Forty-seven patients experienced endoleaks, 18 of which were type 1,25 had one or more type II endoleaks (33 cases in total) and three type III one of these required a conversion to open repair and another required a bypass, indicating a defect in the stent graft material rather than an incomplete seal between the aortic limb stubs and the extensions. There was also one case of endotension and six cases of stent fracture. The authors in this study concluded that the Zenith Flex endograft is an excellent device with good long-term results and low aneurysm-related mortality.
