[Renal angiography and age in various cardiovascular diseases (morphometric analysis)]

Two hundred and fifty-eight angiograms have been analysed, 78 of them are from persons without any renal and cardio-vascular pathology, 184--from patients with vasorenal hypertension. Total area of transversal sections of the arteries is stated (characterizing the arterial bed capacity of the kidney) and its relation to the transversal section area of the renal projection (arterio-renal index). These parameters decrease with age, and are especially noticeable when vasorenal hypertension is present. Stenosis of renal arteries (up to 30%) of various etiology do not practically change the capacity of the renal arterial bed, and when the degree of stenosis increases up to 80%, an essential decrease both in the arterial bed capacity and in the arterio-renal index takes place.
