[Aortorenal angiography and other approaches in the diagnosis of arterial hypertension of renal origin].

The significance of aortorenal and selective angiography of renal arteries with determination of peripheral blood plasma renin activity as well as of individual vein renalis and vein cava blood samples in diagnosing of renal hypertension. Presented is a methodology of an ethiological investigation of arterial hypertension focussed on the investigation of the function and all forms of renal diseases and anomalies. The investigation results showed that among hypertensive patients there was a group of patients with one normal renal artery for each kidney belonging to essential hypertension. In another group of patients, 543 had unilateral and 23 bilateral stenosis of renal artery for whom the index of individual in renalis samples of renin plasma activity indicated the presence of renovascular hypertension. The third group consisted of two patients with malignant kidney tumors and of three female patients with renal hypoplasia for whom a high renin plasma activity and nephrectomy confirmed normalized arterial hypertension of renal origin.
