title: Procedure-related mortality of endovascular abdominal aortic aneurysm repair using revised reporting standards.
abstract: OBJECTIVE
  The aim of this study was to evaluate the definition of Procedure-related mortality after endovascular aneurysm repair (EVAR) as defined by the Committee for Standardized Reporting Practices in Vascular Surgery.
  
  
  METHODS
  Data on patients with an AAA were taken from the EUROSTAR database. The patients underwent EVAR between June 1996 and February 2004 and were analyzed retrospectively. Explicit probability of cause of death was recorded. The time interval from operation, hospital discharge or second interventions till death was recorded.
  
  
  RESULTS
  A total of 589 out of 5612 patients (10.5%) died after EVAR in total follow up and all causes of death were included. 141 (2.5%) patients died due to aneurysms reported after the EVAR procedure of which 28 (4.8%) were ruptures, 25 (4.2%) graft-infections and 88 (14.9%) patients who died within 30 days after the initial procedure (present definition, also known as short term clinical outcome). In addition 25 patients died after 30 days, but were then (at moment of death) still in the hospital, or were transferred to a nursing home for further re-evaluation, or needed second interventions. Taking into account the duration of hospitalization and mortality immediately after procedure-related second interventions, 49 delayed deaths might also be regarded as being EVAR procedure-related.
  
  
  CONCLUSIONS
  Delayed deaths are a considerable proportion of procedure-related deaths after EVAR within the revised time frame.
