[Diagnosis of renovascular hypertension using venous DSA (digital subtraction angiography): image quality and predictive value 1987. Determination of current status].

Using optimal equipment and an adequate examination technique, renal venous DSA for renal artery stenosis is today a diagnostic procedure in 98% of cases. Its sensitivity equals 85%, its specificity reaches 95%. Comparing accuracies and positive predictive values, renal venous DSA is superior to radionuclide studies. Pre-selection of patients with captopril as a pharmacologic test is expected to increase the predictive values of renal venous DSA and to confirm the hemodynamic significance of an angiographically detected renal artery stenosis.
