WebWhat is normal peak systolic velocity? The average PSV in normal volunteers is between 30 and 40 cm/s. 24. A PSV of 35 cm/s is unequivocally normal, whilst a PSV of <25 cm/s following adequate stimulation indicates definite arterial insufficiency. What does ICA CCA mean? CCA = common carotid artery. ICA = internal carotid artery. WebWe aimed to determine the optimal peak systolic velocity (PSV) thresholds for predicting ≥50%, ≥60%, ≥70%, and ≥80% internal carotid artery (ICA) stenosis.
