An observational study in Allograft, Cold Temperature and Saphenous Vein, sponsored by Centre Hospitalier Universitaire de Nīmes. Status unknown at 1 site in France. Open to participants aged 18 Years and older. Per ClinicalTrials.gov, last updated 2024-05-06.

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.
Centre Hospitalier Universitaire de Nīmes is the lead sponsor of 594 studies on the registry; 90 are open to participants now.

Patients receiving a scheduled venous allograft within the CHU of Nîmes for an arterial bypass in the lower limb or an arteriovenous bypass in the upper limb within the framework of the creation of arteriovenous fistulas in dialysis patients, in the absence of available autologous venous material.
