Optimization of duplex velocity criteria for diagnosis of internal carotid artery (ICA) stenosis

A report of the Intersocietal Accreditation Commission (IAC) Vascular Testing Division Carotid Diagnostic Criteria Committee


https://journals.sagepub.com/doi/full/1 ... X211011253
In a real-world correlative imaging study performed with case studies obtained from IAC accredited vascular laboratories, interpretation of carotid duplex ultrasound using SRUCC resulted in significant overestimation of degree of stenosis for both moderate (50–69%) and severe (⩾ 70%) lesions. Owing to the low number of ICA stenoses ⩾ 70% in the final dataset, no definitive conclusions can be made regarding modification of existing SRUCC parameters to further optimize their diagnostic performance for severe ICA lesions. Laboratories currently using SRUCC should consider modification of existing criteria to incorporate more stringent and more accurate parameters for ⩾ 50% ICA stenosis by increasing the PSV threshold to ⩾ 180 cm/sec or requiring the ICA/CCA PSV ratio ⩾ 2.0 in addition to PSV of ⩾ 125 cm/sec.
