Systolic velocity renal artery
WebJun 27, 2008 · It is unknown if the renal artery diameter increases concomitantly with the kidney. This study was performed to assess if peak systolic velocity (PSV) in the renal arteries of paediatric kidneys transplanted to adult recipients is comparable to PSV in the renal arteries of adult kidneys transplanted to adult recipients. Subjects and methods.

WebFour different criteria in total, including two direct criteria in peak systolic velocity (PSV) and renal aortic ratio (RAR) and two indirect criteria in resistance index (RI) and acceleration time (AT) for the measurement of relevant renal artery stenosis are described, each demonstrating highly variable accuracy in studies. WebOct 1, 2012 · RDU imaging and angiography were both done in 313 patients (606 renal arteries). RAS was classified as normal, <60%, ≥60% to 99%, and occlusion. Main outcome measurements included renal peak systolic velocity (PSV), systolic renal-to-aortic ratio (RAR), end-diastolic velocity (EDV), and kidney lengths.
WebRADUS parameters included renal artery peak systolic velocity (PSV) and the renal-aortic ratio (RAR) of flow velocities. Receiver operating characteristic curves (ROCs) and Youden's index were used to calculate optimal RADUS criteria for RAS. Results When traditional RADUS criteria for RAS were used, with a combination of PSV ≥180 cm/s and ... WebRenal artery Doppler ultrasound (DUS) carries a sensitivity of 97%, specificity of 81%, and negative predictive value of 95% for the detection of significant RAS. The success of this technology is highly dependent on the skill of the technician performing the examination. A peak systolic velocity (PSV) of greater than 180 cm/sec has a 95% ...

It is the major cause of hypertension and according to some reports is the cause of hypertension … WebDUS surveillance monitoring for renal stent patency should take into account that a stented artery is less compliant than a native artery and that peak systolic velocity (PSV) and …
WebThe data was analyzed with the help of SPSS version 25.0. Variables like age, gender, diabetes, and Intima-media thickness (IMT) were reported and the mean ± standard deviation of Pulsatility Index, Resistive Index, Peak Systolic Velocity, and End Diastolic Velocity were calculated with a significant p-value, which is less than 0.05.
