Vascular Allografts for AV Access
What is it?
For patients who require hemodialysis access, 38% of them require grafts such as CryoVein and CryoArtery as an alternative to an autologous AV fistula.1 Up to 19% of patients with a synthetic hemodialysis graft have a graft infection.2 CryoVein and CryoArtery are ideal solutions to treat these infections and potentially save the hemodialysis site.3
The Ideal Grafts for:
- Patients in whom an autologous AV fistula is not possible
- Treating infected AV access grafts
- Patients who are at risk of AV access infections
- Patients with a limited number of AV access sites
Key Benefits:
- 72% cumulative patency at 24 months4
- Excellent resistance to infection4
- Outstanding durability5
- Same pulsatile flow dynamics & compliance as autografts6
| Tissue | Diameter | Length | Catalog Number |
|---|---|---|---|
| Femoral Vein | 6mm - 15mm | 10cm - 30+cm | V060 |
| Femoral Artery | 4mm - 5+mm | 10cm - 30+cm | R020 |
| Saphenous Vein | 3mm - 6mm* | 20cm - 80+cm* | V010 |

A CryoVein Femoral Vein Implant Technique for AV Access
To minimize the risk of arterial steal, taper the arterial end of the CryoVein Femoral Vein using an angled cut of the allograft and oversewing the heel of the graft with 6-0 polypropylene suture to create a 4mm3, 5mm7, or 6mm diameter8.
