WebbTypical flow in the proximal internal carotid artery (ICA). Note that the end- diastolic velocity is rather high (11cm/s) compared to the maximal systolic velocity (33cm/s). The ratio is 2.8. This is typical for a low resistance artery. 6.6 What are the normal flow velocities in the carotid artery? Webb26 juni 2024 · Normally, children have slower blood flow than adults, which can be erroneously presumed to be thrombosis on color Doppler sonography (CDS), particularly if the sensitivity is too low, the scale is set wrongly, or filters are too high. Additionally, a poor insonation angle (close to 90°) can cause pseudothrombosis.
