Though variations have been observed, the most common site for bifurcation relative to the vertebral level is at the 4 th cervical vertebra. Common carotid artery division sites have not been studied in Thailand, so our aim was to inventory the site of bifurcation in Thai cadavers.Objective: To determine the site of bifurcation of the common carotid artery relative to the vertebral level. Study design: A descriptive study.Setting: The study was carried out at the Department of Anatomy, Faculty of Medicine, Khon Kaen university, Thailand.ommon carotid artery division sites have not been studied in Thailand, so our aim was to inventory the site of bifurcation in Thai cadavers. Objective: To determine the site of bifurcation of the common carotid artery relative to the vertebral level.
On the left, the common carotid arises directly from the aortic arch whereas, on the right, the origin is from the brachiocephaic trunk. The left common carotid artery can be thought of as having two distinct parts: thoracic and cervical. Since the right common carotid arises cranially, it only really has a cervical portion. In the thoracic section, the left common carotid travels upwards through the superior mediastinum to the level of the left sternoclavicular joint where it is continuous with the cervical portion.
