The scores based on Doppler sonographic spectral features in 14 vertebral arteries with flow reversal and 10 vertebral arteries with normal antegrade flow were correlated with those of ipsilateral internal thoracic (or internal mammary) and subclavian arteries. The statistical analysis revealed significant correlation between the scores of all ipsilateral arteries. We concluded that color duplex ultrasonographic examination of internal thoracic arteries should be carried out in all patients with flow reversal in vertebral arteries. It is especially important in those who are potential candidates for coronary revascularization using in situ internal thoracic artery graft.
