title: Suitability for endovascular aneurysm repair in an unselected population.
abstract: BACKGROUND
  Tertiary referral centres report that up to 60 per cent of patients may be suitable for endovascular repair of abdominal aortic aneurysm (EVAR). The aim of this study was to determine the percentage of abdominal aortic aneurysms (AAAs) presenting to a county-wide vascular service that were suitable for EVAR, and to examine the outcome of subsequent AAA repair in relation to aneurysm morphology.
  
  
  METHODS
  All patients being assessed for AAA repair between January 1998 and December 1999 underwent spiral computed tomography angiography to determine aneurysm morphology and suitability for EVAR. Subsequent outcome for all patients in the study was recorded in a prospective vascular database.
  
  
  RESULTS
  A total of 115 patients was assessed. Sixty-three aneurysms (55 per cent) had one or more absolute contraindications to EVAR, a further 13 (11 per cent) had at least one relative contraindication, and 39 (34 per cent) had no contraindication. Of patients with no absolute contraindication to EVAR, ten underwent successful EVAR, five did not meet recognized criteria for surgery, one awaits EVAR, four remain under observation, one awaits open repair, and 31 underwent open repair without death.
  
  
  CONCLUSIONS
  Only 30 per cent of unselected AAAs presenting to a vascular service are entirely suitable for EVAR; most of these patients can safely undergo open AAA repair. These data suggest that increased use of EVAR is only possible by deploying devices in suboptimal morphology, and in treating patients who would not normally be considered for open AAA repair.
