Brief summary
Vascular access creation in patients with renal failure requiring long-term hemodialysis can be a challenge when there is no more autologous material or in case of infection, in a population undergoing long term dialysis with a longer life-expectancy. Many types of grafts have been used, with its advantages and drawbacks, such as prosthetic grafts (PTFE). Over the past decade, surgeons have used cold stored venous allografts as a biological conduit for hemodialysis, with the idea of avoiding most of major complications including a lower incidence of infection and steal syndrome, with patencies at least equivalent to PTFE. There is only a few data in the litterature, but many surgical teams use it when there is no autologous material or in case of infection. The aim of the study is to give the primary patency of vascular access with this technique, and to assess its long term outcomes.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Intervention free vascular access survival (in days) | 30 days | The interval in days between the vascular access creation and the first successful re intervention (primary patency) |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Thrombosis free vascular access survival (in days) | 30 days | The interval in days between the vascular access creation and the first occlusion with a successful re intervention (primary assisted pantency) |
| Abandonment of the vascular access (in days) | 30 days | The interval in days between the vascular access creation and its abandonment (secondary patency) |
Other
| Measure | Time frame | Description |
|---|---|---|
| Early and late complications (in days) | 30 days | The interval in days between the vascular access creation and the occurence of complications (stenosis, thrombosis, failure, hyperflow, distal ischemia, aneurysm) |
| Incidence of the socio-demographic and clinical characteristics of the patients on secondary patency | 3 years | Compare the duration of secondary patency according to the socio-demographic and clinical characteristics of the patients |
