Comparison of F- B evar vs open surgery
Financed by the Ministry of Health
Windows Trial
F and Bevar
• High risk patients • Anatomically suitable for f or b evar • Treated in Selected Academic Centers
Open Surgery
• All patients recorded in the mandatory
National the Coding Data Base
End points and Analysis
• 30 D Mortality
• 30 D Severe complications
• 30 D Total Cost
• Three groups according to proximal extent
Group 1
F and Bevar = 184
pts Open Surgery = 1382
pts
Group 2
F and Bevar = 42 pts
Open surgery = 225 pts
Group 3

Conclusion: F and Bevar
1) In high risk patients with juxtarenal AAA Fbevar is efficient but not cost effective
2) In TAA aneurysms Fbevar is efficient and cost effective
3) In supra renal AAA Fbevar is neither efficient nor cost effective
