A retrospective analysis of peripheral and renal vein plasma @entity916 activity has been performed in 9 @entity1 with @entity2791 (3 fibromuscular @entity1141 and 7 @entity731 ). In all cases angiography showed a reduction of the arterial diameter of more than 70 p. 100. The renal artery was occluded in 3 cases. All @entity1 received a constant @entity1372 diet (100 mEq/day). Peripheral PRA values were classified as normal or low in 6 cases (less than 2.8 ng/ml/h) and high in one case (greater than 2.8 ng/ml/h): this values concerned 2 cases with @entity432 and 1 case with a narrowing of 90 p. 100. Renal venous @entity916 ratio of 1.5 or more has been found in 8 cases. In one case, the @entity850 was quite symmetrical (70 p. 100) and the ratio less than 1.5. The secretion index has been calculated as the ratio between the venoarterial difference of both affected and unaffected side over the arterial value of PRA (V-A/A). On the more stenosed side, was found a V-A/A ratio of 0.5 or more. This ratio is particularly high in case of artery @entity715 , but there is no correlation between the ratio and the degree of @entity850 . On the contralateral side, where the lesions were less important, the V-A/A ratio was low, ranging from 0 to 0.2; this estimation of @entity916 secretion was found despite a significant @entity850 on the angiography. 7 @entity1 underwent PTA or surgery. 2 kidneys with arterial @entity715 were nephrectomized. In 5 cases the surgical treatment is performed on the 2 sides during the same procedure.(ABSTRACT TRUNCATED AT 250 WORDS)
