title: [Outcome of kidney transplants with multiple arteries].
abstract: OBJECTIVE
  To evaluate the morbidity of multiple artery renal transplants (> 1 artery) and to assess the value of this parameter as a risk factor for complications of renal transplantation in adults.
  
  
  METHODS
  140 renal transplants derived from brain dead donors with multiple arteries (2 arteries = 123, 3 arteries = 17) were reviewed with a mean follow-up of 3 years (6-120 months). Pedicle restoration was performed in 57 cases (end-to-side reimplantation of a polar artery = 17, composite aortic patch graft = 14, multiple procedures = 10, ligation of a polar artery = 8, arterial wound = 5, "gun barrel" anastomosis of 2 arteries = 4). Arteriography was performed systematically in 57 cases, in the absence of any signs suggestive of a vascular complication.
  
  
  RESULTS
  2 recipients died from a vascular complication. 40% of transplants were functional at 5 years. 10 transplantectomies were performed for a vascular complication. 14 recipients returned to dialysis because of a vascular complication. 7.5% of systematic arteriographies revealed stenosis of the transplant artery. 54 transplants developed a vascular complication: thrombosis = 19, stenosis = 25. Three-artery transplants had a vascular morbidity of 50%. "Gun-barrel" anastomoses and polar reimplantations into the main trunk had a vascular morbidity of 40%. The urological morbidity was 10%.
  
  
  CONCLUSIONS
  Multiple artery renal transplants, especially 3-artery transplants and certain pedicle restorations, are associated with a high risk of vascular complications. Arterial anatomy is a selection criterion for the donor and recipient which must be taken into account in renal transplantation.
