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.
The right common carotid originates in the neck from the brachiocephalic trunk; the left from the aortic arch in the thorax. These split into the external and internal carotid arteries at the upper border of the thyroid cartilage, at around the level of the fourth cervical vertebra.n other cases the artery on the right side may arise as a separate branch from the arch of the aorta, or in conjunction with the left carotid. The left common carotid varies in its origin more than the right.
