[Assessment of peak systolic velocity in various-degree isolated stenoses of the internal carotid artery using triplex scanning].

The purpose of this study was to compare the values of the peak systolic velocity in various-degree stenoses of the internal carotid artery, measured by means of triplex scanning with the values revealed by multislice computed tomography. The obtained findings were compared with the data of the Society of Radiologists in Ultrasound Consensus (2003). Significant differences were revealed in the values of velocity for 50-69% stenoses and 70-89% stenoses. Based on the results obtained, we proposed a table with the indication of the peak systolic velocity for various-degree stenoses of the internal carotid artery.
