title: The angiographic evaluation of human renal allotransplants. Functional graft deterioration and hypertension.
abstract: The renal arteriogram is a highly reliable test in the differential diagnosis of early transplant anuria, graft rejection, and hypertension. The reliability of the renal arteriogram was 97.8% in either substantiating or disproving the presence of a suspected episode of graft rejection or renal artery stenosis. The earliest signs of acute humoral and acute rejection were a prolongation of arterial clearance time, diffuse edema with enlargement of the kidney, and progressive deterioration of the nephrogram. Renal artery stenosis may be a sharply localized septum or an elongated narrowing at or distal to the actual site of anastomosis. This was seen primarily in patients' arteriograms more than 60 days after transplantation, and it is important because it is a surgically correctable cause of hypertension.
