Abstract
Renal artery stenosis is one of the most important complications in the natural history of kidney transplantation. Particular care has to be taken in the use of angiography techniques because ot the invasiveness and of the potential toxicity of radiopaque contrast material, even in the less invasive radiological tests, like endovenous sequential angiourography with image subtraction (SAU) and digital subtraction angiography (DSA). Fifty-one patients have been examined with echo-Doppler velocimetry (EDV) and also with SAU in order to verify the previous status of the artery. EDV exhibits a 100% sensitivity: all SAU detected stenosis have been formerly identified via EDV. The non-invasiveness and possibility and of early repetition allows an early diagnosis capability for all transplanted patients. In this way, a surgical intervention may quite often be prevented by a precocious use of endoluminal angioplasty.
