Endovascular Preparation for Kidney Tranplantation

"It concerns all patients with chronic renal failure awaiting a kidney transplant, and presenting a contraindication to the transplant due to their anatomical constraints: major arterial calcifications, iliac dissections, iliac stenoses. They can only receive the kidney transplant after arterial preparation. These patients will be included and will benefit from endovascular preparation for the kidney transplant using a tailor-made arterial stent.~Imaging examinations and follow-up clinical data will be analyzed. Reinterventions and causes of death will be analyzed.~An information sheet will be given to patients; if the patient refuses the use of their data, it will not be collected.~Data collection will be carried out by ARCs or PIs of the centers from medical records. The data will be pseudo-anonymized, entered into a REDCAP database shared between each center."
