title: Lifeline Registry of Endovascular Aneurysm Repair: Registry data report.
abstract: OBJECTIVE
  The goal of the Lifeline Endovascular Registry is to provide a minimal, yet comprehensive, data set of patient follow-up that can evaluate the long-term safety of endovascular grafts used in abdominal aortic aneurysm repair.
  
  
  METHODS
  Follow-up data have been collected on 1757 patients for this first report, including 1646 endovascular graft recipients and 111 surgical patients receiving treatment for abdominal aortic aneurysm.
  
  
  RESULTS
  Logistic regression of 1-year survival indicates that the factors most likely to decrease 1-year survival for the surgical group are renal failure and larger aneurysm size. For the endovascular graft recipients, the presence of renal failure, chronic obstructive pulmonary disease, congestive heart failure, larger aneurysm size, and increased age demonstrates a decrease in 1-year survival. Approximately 80% (1309) of the endovascular recipients have been followed for 1 year. Of these 1309 patients, 17% (222) have incurred an endoleak, and enlargement of the aneurysm has occurred in 4.6% (60). There was a total of 80 (4.9%) endovascular graft recipients converted to surgery. The most prevalent factors causing conversion to surgery were an increase in aneurysm diameter, aneurysm rupture, and the presence of a proximal endoleak.
  
  
  CONCLUSIONS
  Although the data collected by the Registry thus far are limited, we anticipate rapid expansion of the Registry to include data from other manufacturers and investigators. Nevertheless, early data analysis does demonstrate the importance of surveillance of endovascular graft recipients. Through the collection and analysis of Registry data, adverse events continue to be captured, enabling the monitoring of long-term safety of endovascular grafts and the evaluation of graft performance. Data on comorbidities and postoperative factors, collected and evaluated for their effect on survival of the graft recipients, also provide information on optimal patient selection and management. We expect that the next report will support and expand on these findings, providing continuing evidence of the value of a national endovascular registry.
