For patients undergoing secondary peripheral bypass procedures, up to 50% of them do not have suitable autologous tissue to use as a bypass conduit.1 CryoVein Saphenous Vein and CryoArtery Femoral Artery are logical choices in these situations due to their performance2,3 and superior handling characteristics compared to synthetic grafts (e.g. polytetrafluoroethylene grafts).4
- 87% Primary Patency BK at 1 Year2
- 70% Limb Salvage Rates BK at 4 Years5
- Excellent Resistance to Infection3
- Same Compliance and Flow Dynamics as Autografts6
- Superior Handling Characteristics Compared to PTFE grafts4
- Easy to Suture
Alternative to Amputation
- Decreased Mortality at 1 Year: CryoVein 28% vs. AKA: 49%7
- Increased Quality of Life8
