title: Outcome and quality of life after endovascular abdominal aortic aneurysm repair in octogenarians.
abstract: OBJECTIVE
  This study determined outcome and quality of life (QOL) in octogenarians, compared with patients aged <80 years, 1 year after endovascular aortic aneurysm repair (EVAR).
  
  
  METHODS
  From March 2009 until April 2011, 1263 patients in the Endurant Stent Graft Natural Selection Global Postmarket Registry (ENGAGE) registry with an abdominal aortic aneurysm were treated with EVAR using the Endurant endograft (Medtronic Cardiovascular, Santa Rosa, Calif). The patients were grouped according to those aged ≥80 years (290 [22.9%]) and those aged <80 years (973 [77.1%]) at the time of the procedure. QOL was assessed using composite EuroQoL 5-Dimensions Questionnaire (EQ-5D) index scores. Baseline, perioperative, and follow-up data were analyzed at 1 year.
  
  
  RESULTS
  Octogenarians had poorer anatomic characteristics. The technical success rate was almost 99% for both cohorts, with no deaths. The duration of the implant procedure was significantly longer in the elderly patients (P = .002), with significant differences in overall (P < .001) and postprocedure (P < .001) hospital stays in favor of the younger group. At 1 year, there was a significant difference in all-cause mortality (P = .002) and in the number of major adverse events (P = .003), including secondary rupture (P = .01), to the detriment of octogenarians. There were no significant differences in conversion to open surgery or in overall secondary endovascular procedures. The octogenarians scored lower in their overall health care perception (P < .001) but with no significant difference in the EQ-5D index. Compared with the group aged <80 years, they had still not completely recovered their QOL after 1 year (P = .01).
  
  
  CONCLUSIONS
  Octogenarians are more difficult to treat by EVAR than younger patients due to poorer anatomic suitability and a higher incidence of complications. Recovery of QOL in octogenarians takes longer (>12 months) than expected.
