In 3806 patients with vasorenal hypertension the results of kidney angiographic investigation were analyzed. In order to study the efficacy of application of intravenous digital substructional angiography (DSA), the data, obtained in 1621 patients using this method, were compared with such in general group of patients. Informativeness of DSA had constituted 88.9%. Accompanying chronic disease of intestine, excessive body mass, nephrosclerosis are complicating interpretation of obtained results in 10.1% of observations. Possible conduction of ambulatory investigations, decrease traumaticity, invasiveness, duration of procedure, shortening of financial expense constitute the main advantages of DSA. Application of method is recommended in all patients with vasorenal hypertension in ambulatory environment.

In an evaluation of 25 patients, Vmax, Vmin, ratio in the stenosed renal artery (RA) was found to be significantly lower as compared with RA of control group patients, whereas the contralateral RA did not show any changes in the above parameter. Thus, under unilateral RA stenosis, there is an upward tendency in the difference between the values for stenosed RA and contralateral RA. Estimators of asymmetry appear to be significantly higher in main group patients, which fact suggest to us that results from doppler ultrasonography might provide an additional index to be taken into consideration in a setting where a patient is to undergo angiography.
