Abstract: . . .  however, this can be improved to 98% with a specificity of 84% when maximum intensity projections and three dimensional techniques are used. Renal vein renin measurements: Although 90% of the patients with RVH and lateralization of renin values have a positive response to revascularization (angioplasty or sur- gery), 50% of the RVH that do not show lateralization also benefit from the correction of the stenosis (21). At present, this test is rarely used, except for the assessment of patients with lesions in both renal arteries, in order to deter- mine which kidney has the more significant contribution to the maintenance of the hypertension . In our experience, when there is high clinical . . .
