title: Comparison of endovascular aortic repair and open surgical repair for ruptured abdominal aortic aneurysm.
abstract: OBJECTIVE
  To compare the clinical efficacies of endovascular aortic repair(EVAR)and open surgical repair(OSR)for ruptured abdominal aortic aneurysm(rAAA).
  
  
  METHODS
  The clinical data of 28 rAAA patients undergoing emergent treatment between February 2002 and February 2013 in PUMC Hospital were retrospectively reviewed. Among them 13 cases were treated by EVAR and 15 cases by OSR.
  
  
  RESULTS
  Before the surgery,the general conditions,comorbidities,and hemodynamics were not significantly different between these two groups(all P>0.05),although the EVAR group had significantly higher mean age than OSR group(P=0.041). In the perioperative period,the EVAR group showed significantly lower 30-day mortality(P=0.044),less blood loss(P=0.005),less blood transfusion(P=0.003),less infusion quantity(P=0.000),shorter length of procedure(P=0.001),and shorter hospital stay(P=0.020). Also,the EVAR group had no severe perioperative complications and showed superior 1-year follow up survival(P<0.05).
  
  
  CONCLUSIONS
  EVAR is an effective treatment for rAAA and can improve the clinical outcomes. EVAR may be adopted as the first-line treatment for rAAA,especially for the aged.
