[Renal blood circulation in patients with vasorenal hypertension (based on ultrasonic dopplerography data)].

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.
