[Renal transplantation on vascular prosthesis].

Area of Science:

• Nephrology
• Vascular Surgery
• Transplantation Medicine

Background:

• Aortoiliac axis calcification poses challenges for renal transplantation.
• Vascular prosthesis arterial anastomosis is a rare but considered intervention.
• This procedure is associated with significant difficulty and morbidity.

Purpose of the Study:

• Evaluate overall and specific survival of renal transplants with prosthetic arterial anastomosis.
• Assess complications associated with this surgical approach.
• Analyze the evolution of renal function post-transplantation.

Main Methods:

• Multicenter retrospective data collection (DIVAT cohort plus 4 additional centers).
• Inclusion of transplants with prosthetic arterial anastomosis.
• Study of 34 patients undergoing this procedure.

Main Results:

• Median follow-up of 2.5 years.
• Median transplant survival of 212 days.
• High rates of post-transplant complications including death (10%), return to dialysis (80%), and surgical issues (stenosis, fistula).

Conclusions:

• Renal transplantation with vascular prosthesis anastomosis is a viable alternative to dialysis for carefully selected patients.
• Long-term follow-up and defined selection criteria are crucial for improving outcomes.
• A national registry could aid in long-term survival assessment and criteria refinement.
