[Vascular complications of kidney transplant. Stenosis of the renal artery].

The present paper analyzes the incidence of vascular complications and their treatment, in a series of 500 consecutive Heterotopical Kidney Transplants (KT), performed in our Service between January 1978 and December 1988. There was a total of 14 (2.8%) complications of which 8 (1.6%) correspond to renal artery stenosis. Of the 8 cases with renal artery stenosis, in 2 of them primary surgical treatment was indicated. The first one was a transplantectomy (TRX) and the second one reconstructive direct surgery. In the 6 remaining patients a Percutaneous Transluminal Angioplasty (PTA) was indicated. In three of these patients the stenosis resolved although one of them needed a second dilatation. In the last three there was: a thrombosis requiring TRX, a post dilatation anuria added to failure in the treatment of HT and which, finally, had to undergo surgery, and a third failure that could not be resolved by surgery and had to be subjected to graft nephrectomy. One of the patients in the surgical group died.
