Traditional anatomic techniques for central line access rely on the sternocleidomastoid as the principle landmark. This is readily identified under U/S as well. Two vessels deep to the sternocleidomastoid are identified at the lateral neck; the more lateral, larger, thin walled, superficial vessel which is compressible with light probe pressure represents the internal jugular vein. The medial, deeper, thicker walled vessel with a characteristic pulsation, and higher resistance to collapse represents the common carotid artery.
