Vascular complications in renal transplantation: a single-center experience in 1367 renal transplantations and review of the literature.

Renal transplantation is the treatment of choice for end-stage renal disease. Vascular complications in renal transplantation are not uncommon and may often lead to allograft loss. The most common vascular complications are transplant renal artery stenosis, transplant renal artery thrombosis, transplant renal vein thrombosis, biopsy-induced vascular injuries, pseudoaneurysm formation, and hematomas. Transplant renal artery and vein thrombosis have an early onset and a dramatic clinical manifestation and usually lead to allograft loss. In contrast, transplant renal artery stenosis has better treatment possibilities, whereas the rest do not occur so often. In our institution, 1367 renal transplantations were performed from September 1980 to April 2005. During this period, we encountered 38 major vascular complications leading to graft loss and 19 transplant renal artery stenoses with successful treatment in the majority of cases. According to these data, we can conclude that renal transplantation is a safe therapeutic procedure for renal failure.
