title: Endovascular treatment of ruptured abdominal aortic aneurysms: aorto-uni-iliac or bifurcated endograft?
abstract: OBJECTIVE
  This study evaluated the safety and technical and clinical success rates of positioning endovascular endografts (EG) in ruptured abdominal aneurysms.
  
  
  METHODS
  Patients with a ruptured abdominal aortic aneurysm confirmed by contrast-enhanced computed tomography angiography (CTA) were eligible for the analysis. Of 67 patients, 42 (62.7%) were treated with EG. Thirteen patients (30.9%) received an aorto-uni-iliac EG (group A) and 29 a bifurcated EG (group B). Patients were divided for comparative analysis according to the configuration of the EG implanted.
  
  
  RESULTS
  The primary technical success rate was 100%; the primary clinical success rate was 95% (40/42). There were two intraoperative deaths (4.7%) related to intractable shock. No patient required conversion to open repair. Overall, 12 patients (28.5%) died within 30 days. The in-hospital death rate was 30.9% (13/42). Hospital mortality rate was statistically higher in group A; the type of EG and intensive care unit admission were the only independent predictors of hospital mortality.
  
  
  CONCLUSIONS
  In our experience, a higher mortality rate was observed for the aorto-uni-iliac configuration; shock at admission was confirmed as the most important factor for postoperative survival.
