Transcranial Duplex Evaluation of Internal Carotid Artery Flow Direction during Transcarotid Artery Revascularisation with Integrated Embolic Protection

In this study, distal ICA flow reversal was not present during TCAR for a significant proportion of patients despite retrograde flow being visually observed in the CCA sheath. Addition of distal embolic protection in all patients appears reasonable for effective stroke risk reduction.
