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.
目的
描述肯尼亚人颈动脉的形态及解剖变异情况。
设计
描述性横断面研究。
地点
内罗毕大学人体解剖学系。
研究对象
解剖了40具尸体的80条颈动脉。
结果
最常见的颈动脉分叉位置较高（高于参考点）的情况在63.8%的血管中出现，30%的血管中颈外动脉位于颈内动脉的前外侧。舌面干是颈外动脉最常见的变异。右颈总动脉起源位置较高和较低的情况分别在10%和2.6%的血管中出现。
结论
颈动脉显示出重要的变异性，因此在颈部手术过程中临床医生应予以谨慎对待。
