Objective:
To describe the topography and anatomical variations of the carotid arteries among Kenyans.
Design:
A descriptive cross-sectional study.
Setting:
Department of Human Anatomy, University of Nairobi.
Subjects:
Eighty carotid arteries of forty cadavers were dissected.
Results:
The bifurcation of the commonest carotid artery was high (above the reference points) in 63.8% of vessels and the external carotid was antero-lateral to the internal carotid artery in 30% of the vessels. A linguo-facial trunk was the most common variation of the external carotid artery. The origin of the right common carotid artery was high and low in 10% and 2.6% of vessels respectively.
Conclusion:
The carotid arteries show important variability and thus emphasise caution for clinicians during surgical procedures in the neck.

Overview of Systemic Arteries
Systemic circulation is the part of the cardiovascular system that carries oxygenated blood away from the heart to the body's tissues and returns deoxygenated blood back to the heart.

Arteries
Arteries circulate oxygenated blood from the heart, except the pulmonary artery, which transports deoxygenated blood to the lungs. Large arteries, such as the aorta, have...
