RESUMO
BACKGROUND: The goal of this study was to show the importance of the identifying potential carotid and vertebrobasilar stenosis with Computed Tomography Angiography (CTA) in severe coronary artery disease. METHODS: In 109 patients, CTA of the carotid and the vertebrobasilar system were taken in the six months following the Coronary Angiography (CA). Coronary arteries and carotid vertebrobasilar system stenosis were considered significant at more than ≥ 50 %. RESULTS: A significant statistical relationship was found between a coronary artery group of three-vessel disease (3-VD) and stenosis of the cervical segments of the right (p = 0.022) and left internal carotid artery (ICA) (p = 0.001); intracranial segments of the right (p = 0.007) and left ICA (p = 0.020), and the right vertebral artery (VA) (p = 0.008). There was a significant statistical relationship between Gensini score and stenosis of both the right (p = 0.030) and the left ICA cervical segments (p = 0.003). CONCLUSION: In patients with severe coronary artery disease especially in 3-VD, CTA scan may be useful diagnostic tool for identifying stenosis of the carotid arteries, particularly in the intracranial segments of the ICA and in the preforaminal (V1) segment of the VA (Tab. 4, Fig. 3, Ref. 22).
