title: The role of cell salvage autotransfusion in abdominal aortic aneurysm surgery.
abstract: OBJECTIVE
  Abdominal aortic aneurysm (AAA) repairs, both elective and rupture, are associated with significant blood loss often requiring transfusion. Cell-salvage autotransfusion has been developed to reduce the need for allogeneic blood. We review the literature to delineate the role of cell salvage in reducing allogeneic blood use in open AAA repairs.
  
  
  METHODS
  A systematic search of the English-language literature was performed using the PubMed, Embase and Cochrane databases up to August 2010.
  
  
  RESULTS
  Twenty-three studies were identified. Whilst some data are conflicting, cell salvage appears to reduce overall use and exposure to allogeneic blood, and reduces length of intensive care unit and hospital stay after elective AAA repairs. There may be additional benefit by combining cell salvage with other blood-conservation techniques. Use of cell salvage in ruptured AAA repairs consistently reduced blood-product requirements.
  
  
  CONCLUSIONS
  Cell salvage appears to reduce blood-product use in both elective and rupture AAA repairs. Owing to the heterogeneity in methodology of published data, further study may be required before cell salvage becomes standard practice in open AAA repairs.
