title: [Natural history of vascular ports for hemodialysis after renal transplantation].
abstract: BACKGROUND
  The objective of this study was to assess the long-term outcome of AV shunts in renal transplant recipients, to discuss mechanisms affecting their functioning and the surgical strategy designed to optimally preserve the venous capital in the hypothesis of a return to dialysis.
  
  
  METHODS
  160 renal transplant recipients, with a mean age of 47 years, were reviewed. AV shunts were performed at the wrist in 95% of cases and in the cubital fossa in 13% of cases. The AV shunt had been performed an average of 29 months before renal transplantation.
  
  
  RESULTS
  62% of AV shunts were considered to be functional with a mean follow-up of 69 months after transplantation and 95 months after creation. The intraoperative and early and late postoperative thrombosis rates were 6%, 7.5% and 17%, respectively. The AV shunt was subsequently closed in 12 patients (7.5%).
  
  
  CONCLUSIONS
  Native distal AV shunts, although not used after renal transplantation, have a prolonged survival. The main risk is thrombosis which can be prevented intraoperative and perioperatively. These results encourage a conservative attitude to all well tolerated AV shunts.
