CT Anatomy Neck Vasculature (Coronal) - Video Lesson

Hey everybody, welcome back. This lesson is about the vasculature of the neck as seen in CT imaging in the coronal plane. This is a CT angiography study of the head and neck. Iodinated contrast was injected intravenously and the scan was timed to demonstrate maximum opacification of the arteries. We will see some opacification of the veins, but that was not the intent of this study. All of the arteries that ultimately supply the head and neck originate at the aortic arch. The aortic arch has three branches. We can see the first branch, which is the brachiocephalic artery. This trunk immediately bifurcates into the right subclavian artery to supply the right arm and the right common carotid artery to supply the right side of the head and neck. We can also see the second branch, which is the left common carotid artery. Finally, we can see the third branch, which is the left subclavian artery. In this plane, we cannot see where the subclavian artery originates at the aorta, but we can see it turning laterally to supply the left arm. All
