Diastolic reversed flow was determined in 7 (39%) of 18 patients with AR grade 3\u20134. Three patients (25%) with AR grade 2 and 4 patients (22%) with AR grade 3\u20134 had zero level diastolic flow in the common carotid artery. Statistically significant changes of decreased end\u2010diastolic velocity, increased peak systolic velocity\/end\u2010diastolic velocity, resistivity index, and pulsatility index were revealed, especially in AR grade 3\u20134 compared to controls.
