Why to stent a Fenestration/Branch?
• Fenestration– Achieve better sealing (covered stent)– Maintain the fenestration in position
• Branch– Bridging covered stent to seal
To answer the Question…
• Review of our database (2001-2014)
– FEVAR for complex AAA
– FEVAR/BEVAR for TAAA
Overview
• FEVAR for complex AAA
– 457 pts
• F/B-EVAR for TAAA– 214 pts
Total target vessels: N=1712*– Impossible cannulation (antegrade): N=29/1712 (1.7%)
* Scallops excluded
Impossible Antegrade Cannulation (N=29)
• Vessels lost: N= 12/1712 (0.7%)
• Vessels attempted to save by Retrograde Cannulation: N= 13/1712 (0.8%)
