Die venöse digitale Subtraktionsangiographie der Nierenarterien bei Hypertoniekranken

Abstract

We carried out 1890 venous digital subtraction angiograms; this included 113 patients with hypertension in order to exclude renal artery stenosis. On four occasions it was used following surgery on a renal artery. Renal artery stenosis or occlusion was demonstrated in twelve patients, and other vascular diseases or anomalies were found in 24. Two abnormal renal arteries were found following renal artery surgery. The results are compared with smaller groups of patients examined by DSA, and with the results of conventional subtraction methods reported in the literature. In only eight patients (6.8%) DSA provided insufficient information and had to be supplemented by aortography. The method has proved to be a valuable and simple screening method for the investigation of hypertension.

Digital subtraction angiography: The intravenous approach

“…Interest focused on the renal circulation [11], where the above mentioned advantages of iv-DSA were attractive. In the last 2 years, with improved equipment, it has become a widely accepted method to check up patients with renal hypertension ( Fig.…”
