Abstract:
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.

Blood Pressure
The average BP in an adult is typically around 120/80 mmHg (millimeters of mercury). In this measurement, the numerator (120) indicates the systolic pressure, which is the pressure in the arteries during the contraction of the heart's ventricles as blood is expelled. The denominator (80) represents the diastolic...
Assessing Blood pressure using a doppler ultrasound
Pre-Procedural Guidelines for Doppler Ultrasound Blood Pressure Assessment:
Preparation of Equipment:
Special considerations while measuring blood pressure
Monitoring Both Arms:
Monitoring BP in both arms during the initial assessment is advisable, as the systolic value may differ by five to ten mm Hg between arms. For subsequent BP assessments, use the arm with the higher reading.
