title: Early intervention effects of open repair and endovascular aortic repair on patients suffering from 40-54 mm abdominal aortic aneurysms: single center experience.
abstract: BACKGROUND
  We conducted this study to explore the early intervention effects of open repair (OR) and endovascular aortic repair (EVAR) in treating abdominal aortic aneurysm (AAA) patients (maximum diameter 40-54 mm).
  
  
  METHODS
  We retrospectively analyzed patients under 65 years old with maximum AAA diameter 40-54 mm in our hospital from January 2010 to January 2016 (among which there are 38 EVAR cases and 18 OR cases) and compared their short mid-term operation effects.
  
  
  RESULTS
  The time of the operation, bleeding volume and volume of blood transfusion during operation in the EVAR group are significantly lower than those in the OR group; differences are statistically significant (P<0.05). The operation success of the rats in both groups was 100%; the 30-day death rate was 0% and the recurrence rate was 0%; differences are not statistically significant. The total incidence rate of complications in the OR group was 22.2% while it was 5.3% in the EVAR group; differences are statistically significant (χ2=4.114, P=0.043).
  
  
  CONCLUSIONS
  Early intervention (regardless of whether open or endovascular repair is used) is a feasible method for young patients with asymptomatic AAAs of 4.0 cm to 5.5 cm diameter.
