Peak Systolic Velocity

Peak Systolic Velocity (PSV) Predictor is an app for use as a clinical screening tool for patients who have undergone endovascular treatment with Covered Endovascular Reconstruction of Aortoiliac Bifurcation (CERAB) stents. This app will take geometric dimensions and blood flow velocities from ultrasound scanning as well as Ankle Brachial Index readings as input. The app will calculate the predicted maximum velocity and together with the ultrasound measured maximum velocity, it will determine whether the readings are falling inside or outside of acceptable range and deemed to be “Normal” or “Abnormal” . IF abnormal, computed tomography angiography is recommended to investigate re-stenosis.
