An update on the important findings from the EUROSTAR EVAR registry.

This article summarizes the important findings to emerge from the European Collaborators on Stent-Graft Techniques for Abdominal Aortic Aneurysm Repair (EUROSTAR) Registry since its inception in 1996. The Registry is an open observational study of the outcomes from endovascular aneurysm repair (EVAR). Data have been contributed, on a voluntary basis, by 135 vascular centers from 18 European countries. Patients are registered prospectively, and data analysis is on an intention-to-treat basis. Results from the first generations of endograft were characterized by excellent early results but poor durability of abdominal aortic aneurysm repair. EUROSTAR data have played a vital role in informing the technical evolution of subsequent generations of endograft and their clinical application. The latest data from EUROSTAR show significant improvements in all outcome measures, most importantly, those relating to durability. EUROSTAR has tracked and informed the evolution of EVAR. Improving results confirm that substantial progress has been made since 1996. EUROSTAR continues to contribute to this ongoing process.
