[Diagnosis of renovascular hypertension by intravenous digital subtraction angiography and renal sequential scintigraphy].

Intravenous digital subtraction angiography (DSA) and 131J-hippuran clearance (NSS) were evaluated in 113 patients, both methods were made as screening tests for renovascular hypertension. In 9 examinations DSA was not diagnostic, in 18 patients arterial wall lesions were found. The dynamic renal imaging with hippuran showed alterations in 86 patients, 2 patients with renal arterial stenosis had normal findings. Combination of both methods yields good results in estimation of the haemodynamic significance of a renal arterial narrowing.
