Abstract
Carotid arteries are the main sources of blood to the structures in the head and neck
region. Normally, the right and left Common Carotid arteries differ in origin and length, they
persue a similar course and distribution after being divided into External and Internal carotid
arteries in the neck. The normal course and distribution of these arteries has been studied and
well documented. Although some of the anatomical variations in these structures have been
identified and reported earlier, such data is available only for western populations.
During this study, the origin, course and the level of bifurcation of the common carotid
arteries, branching pattern and important relations of the external carotid arteries and the
diameters of these vessels at different anatomical levels were looked into while special attention
was paid to identify the anatomical variations.
Although it is not possible to draw any final conclusions, the results of this preliminary
study shows that anatomical variations of common external carotid arteries are relatively
common among the Sri Lankans. Higher or lower bifurcation and unusually tortuous course of
common carotids and several variations in the course and branching pattern of external carotids,
which were found during the study, are reported here.
