title: Results of endovascular repair of inflammatory abdominal aortic aneurysms. A report from the EUROSTAR database.
abstract: OBJECTIVE
  To investigate the results following endovascular treatment of patients with inflammatory abdominal aortic aneurysms (IAAA).
  
  
  METHODS
  Retrospective study based on the EUROSTAR registry.
  
  
  METHODS
  Patients included in the EUROSTAR registry with IAAA (n=52, 1.4%) were compared to those having aneurysms without aortic fibrosis (n=3613, 98.6%). The mean follow-up period in patients with IAAA was 23 months (range 1-60). In 11 of the patients detailed information on the effect of endovascular repair and perianeurysmal fibrosis and ureteral entrapment was obtained by a dedicated questionnaire.
  
  
  RESULTS
  Twelve patients (23%) with IAAA had preoperative impairment of renal function and five had known hydronephrosis. Variables that were significantly associated with IAAA included younger age (p<.0001, mean difference 5.9, CI 3.7-7.9) and lower pulmonary risks score (OR 0.38, CI 0.19-0.74). At completion of the endovascular procedure, device stenosis was more frequently observed in patients with IAAA (OR 18.1, CI 3.52-93.0). There were no differences with regard to the rates of mortality, rupture or conversion in patients with IAAA and controls. In the majority, the aneurysm size regressed irrespective of nature of aneurysm. Of the 11 patients with a detailed assessment three had deterioration of renal function and three still had ureteral entrapment during follow-up.
  
  
  CONCLUSIONS
  Despite persistence of perianeurysmal inflammation in a proportion of patients operative and midterm results of endovascular repair were comparable in the patients with inflammatory and standard AAA.
