title: Anastomotic femoral aneurysms: increase in interval between primary operation and aneurysm formation.
abstract: OBJECTIVE
  Anastomotic pseudoaneurysms continue to be a late complication of vascular surgery, particularly following prosthetic graft procedures. The purpose of this study was to investigate if a previously reported increase in interval between the original operation and the development of pseudoaneurysm was still valid.
  
  
  METHODS
  Retrospective study.
  
  
  METHODS
  We reviewed the records of 76 patients who presented with 90 femoral aneurysms. The median age was 69 years (range: 39-83). The commonest previous vascular surgery was a aortofemoral bypass in 61 cases.
  
  
  RESULTS
  The interval between the original operation and the repair of the pseudoaneurysms was 9 years (range 1 month to 26 years).
  
  
  CONCLUSIONS
  This study confirms the previously noted trend of an increasing time to aneurysm formation from 3 years before 1975, 5 years between 1976 and 1980, and 6 years between 1981 and 1990.
