WebA receiver operator curve (ROC) analysis was used to determine optimal DVC (peak systolic velocity [PSV], end-diastolic velocity [EDV], and CA or SMA/aortic systolic ratios) for detecting ≥50% and ≥70% ISS. These were compared to duplex velocities obtained from 97 native CAs and 74 native SMAs with ≥50% stenosis done in the same study period. WebNormal blood flow velocities decrease as you go from proximal to distal. These are some common normal peak systolic velocities: Peripheral artery stenosis is considered significant when the diameter reduction is 50% or greater, which corresponds to 75% cross sectional area reduction. The stenosis PSV to pre-stenotic PSV is 2.0 or greater.
