[Postanastomotic renal-artery stenosis after renal transplantation].

A particular kind of renal-artery stenosis was observed in three of 60 renal transplantations performed between 1969 and 1974. It was always 1.0-1.5 cm distal to the anastomosis and, as histological examination demonstrated, was definitely due to vessel injury after removal of the transplant. To avoid it the proximal arterial stump should be cut off before transplantation. The postanastomotic region must be dissected free during the operation and an extended graft venoplasty or sleeve resection performed.
