[Arterial stenosis in kidney transplant patients]

A short literary review is presented on the frequency and characteristics of the stenosis of the arterial anastomosis or of sections next to it in patients with transplanted kidney. The histories of three patients are reported. In two of the patients in the 6th and 7th month following the transplantation a severe arterial pressure appeared and a systolic murmur could be heard medially from the transplanted kidney. By renal vasography a marked stenosis of the anastomosis of the renal artery with the hypogastric artery was found. The stenosis was not corrected in time which led to its thrombosis and explantation of the kidney. In the third patient the renal vasography did not reveal stenosis of the anastomosis. In this case the symptoms were due to a chronic crisis of rejection of vasal type. The appearance of severe persistent arterial hypertension 6-7 months after a kidney transplantation is a signal for possible stenosis of the arterial anastomosis which requires timely examination and surgical correction if found.
