title: [Comparison of surgical versus endovascular stent-graft repair of thoracic and thoracoabdominal aortic aneurysms in terms of postoperative organ failure].
abstract: BACKGROUND
  We conducted this study to clarify whether the incidence of organ failure after endovascular stent-graft repair of thoracic aneurysm (TAA) and thoracoabdominal aneurysm (TAAA) is much higher than that after surgical repair.
  
  
  METHODS
  The diseases for surgical repair (surgical group) were TAA in 29 patients and TAAA in 19 patients. Fourteen patients underwent stent-graft repair for TAA and TAAA (stent group). Incidences of preoperative complications in the two groups were compared. Postoperative organ failures, changes in SOFA score and numbers of SIRS criteria were assessed over a period of 7 postoperative days.
  
  
  RESULTS
  Although the incidence of preoperative complications in the stent group was significantly higher than that in the surgical group, postoperative organ failure in the surgical group was more frequent than that in the stent group. SOFA score in the stent group during the first 3 postoperative days was significantly smaller than that in the surgical group. However, the number of SIRS criteria in the stent group was significantly higher than that in the surgical group on the first postoperative day.
  
  
  CONCLUSIONS
  Endovascular stent-graft repair for arotic aneurysm may be less invasive, leading to a reduction in the incidence of postoperative organ failure in high-risk patients.
