Study Details

Study Description

Brief Summary

The study investigators propose to perform a blood test before and after allograft placement in all patients receiving a cold-stored venous allografts at the University Hospital of Nîmes to study the occurrence of FVFA-related ASD in these patients.

The aim of this work is to characterize a possible immune reaction generated by the implantation of venous allografts prepared according to the BIOPROTEC method. In case of a proven immune reaction, the study will allow a modification of our current attitude and to exclude patients potentially eligible for renal transplantation at the time of venous allograft placement, or to perform in these patients an allo-compatibility test with the venous allograft preoperatively and thus protect these patients from an increased risk of subsequent organ transplant rejection.
