title: Direct Revascularization with Autotransplant Technique for a True Aneurysm of the Renal Artery 20 Years after Kidney Transplantation.
abstract: BACKGROUND
  True degenerative aneurysm of renal artery represents a very rare evolution in kidney transplantation. The cases presented in the literature are usually perianastomotic or mycotic pseudoaneurysm related to surgical technical defects or local infections.
  
  
  METHODS
  Herewith, we present the case of a voluminous true aneurysm developed in a young patient transplanted at our hospital 20 years before. All follow-up ultrasounds were always normal until the last disclosing a voluminous aneurysm of the transplanted renal artery. The subsequent angio-CT-scan confirmed the presence of a 52-mm saccular dilatation of the renal artery. For the complex anatomy, the endovascular approach was excluded, and a surgical revascularization was staged. We treated this lesion with the autotransplant technique, preserving the transplanted kidney, resecting the aneurysm, and performing a direct anastomosis after cold perfusion of the kidney.
  
  
  CONCLUSIONS
  The autotransplant technique demonstrated to be a safe and effective approach in this challenging and very unusual situation.
