This article is another in a long series of publications derived from the EUROSTAR registry. This publication focuses on the late outcomes following endovascular repair with 2 of the first commercially available devices in Europe. The researchers conclude that late failure modes are frequent and sometimes lead to aneurysm rupture and aneurysm-related mortality, and that nonfatal procedure-related complications and secondary interventions are common. They also have determined that these complications are more frequent and survival is poorer in patients whose aneurysm size at initial treatment was greater than 55 mm. Specifically, the cumulative survival rate at 8 years in those with small aneurysms was 74.5%; in those with large aneurysms, it was 49.6%.
