. There is a filling defect in distal aspect of the basilar artery beyond the origins of the superior cerebellar arteries. There is also nonvisualization of the right posterior cerebral artery. Posterior communicating arteries are small and not definitively seen on the right. The left posterior cerebral artery and the superior cerebellar arteries are patent. Atherosclerotic changes involving the proximal basilar and distal vertebral arteries. There is heavy atherosclerotic calcification of the cavernous internal carotid arteries with mild to moderate degrees of stenosis. Otherwise no evidence of significant stenosis involving the anterior or middle cerebral arteries. The superficial and deep intracranial venous drainage is unremarkable. There is no abnormal enhancement of the brain. There are severe atherosclerotic calcifications of the aortic arch and the origins of the great vessels without significant stenosis. The origins and cervical segments of the left and right vertebral arteries demonstrate atherosclerosis. There is mild outpouching or ectasia of the aortic arch. There are moderate atherosclerotic calcifications of the carotid arteries at their carotid bifurcations, with less than 50% ICA bulb stenosis bilaterally. The right vertebral artery is hypoplastic and demonstrates superimposed atherosclerotic changes with high-grade stenosis involving the right the V3 segment and better opacification involving the right V4 segment which may be related to retrograde flow. Patient is status post endotracheal intubation, with endotracheal tube terminating superior to the carina. Oroenteric tube is visualized extending into the visualized portion of the thoracic esophagus. There are foci of air noted involving the right jugular and subclavian veins with smaller foci elsewhere which may related to venous line placement.
