Endovascular repair of abdominal aortic aneurysms. Results from the EUROSTAR registry. EUROpean collaborators on Stent-graft Techniques for abdominal aortic Aneurysm Repair.

EUROSTAR (EUROpean collaborators on Stent-graft Techniques for abdominal aortic Aneurysm Repair) was established for the purpose of combining and studying data on endovascular abdominal aortic aneurysm (AAA) repair. EUROSTAR is independent of any commercial interest, and aims to provide scientifically reliable assessment of endovascular AAA grafting. The results of 2,016 patients from 98 European institutions have been collected and analysed. Despite the minimally invasive nature of endovascular aneurysm repair, a variety of complications do occur with considerable frequency. Complications are more often encountered in patients with large aneurysms, advanced age, and if adjuvant procedures are required. In addition, a compromised cardiac and general medical status has adverse effects on the risk of systemic complications. The experience of the operating team is an important factor, influencing device- and procedure-related complications. The observed 18-month endoleak-free survival reflects a satisfactory mid-term result.
