title: Endovascular repair of abdominal aortic aneurysm in octogenarians: an analysis based on EUROSTAR data.
abstract: OBJECTIVE
  To investigate the early and late outcome after endovascular treatment of abdominal aortic aneurysm (EVAR) in octogenarians compared with patients aged < 80 years.
  
  
  METHODS
  Patients treated for abdominal aortic aneurysm (AAA) with endovascular repair during the period 1996 to 2004 were collated in the EUROSTAR registry. This study group consisted of 697 patients aged > or = 80 years. Comparison was made with 4198 patients aged < 80 years with regard to the incidence of preoperative characteristics and outcomes of the procedure.
  
  
  RESULTS
  The proportion of octogenarians treated by EVAR increased during the study period, from 11% in the first year to 18% in the last year. Octogenarians more frequently had cardiac disease, impaired renal function, and pulmonary disease (P = .03, P < .0001 and P = .0001). Thirty-two percent of the octogenarians were recorded unfit for open surgery as opposed to 22% in younger patients (P < .0001); they also had a larger aneurysm diameter (62 vs 58 mm, respectively; P < .0001). The 30-day and in-hospital mortality in octogenarians was 5% vs 2% in the younger group (P < .0001). More device-related complications and systemic complications, including cardiac disease, were noted in octogenarians (7% vs 5% and 19% vs 11%, P = .03 and P < .0001, respectively). This group of patients also had a higher incidence of postoperative hemorrhagic complications, including hematoma (7% vs 3%, P < .0001, respectively). No differences in conversion to open repair and post-EVAR rupture rate were observed. Aneurysm-related mortality and late all-cause mortality was 7% vs 3% and 10% vs 7%, both P < .0001.
  
  
  CONCLUSIONS
  Our study supports that EVAR might be considered when treating elderly patients, provided their aneurysms are anatomically suited for the endovascular technique. The risk for late complications compared with open repair may be outweighed by a lower early mortality as well as a shorter time for physical recovery.
