Unusual High Bifurcation Of Common Carotid Artery Among Eastern Population- A Case Study

Variation of the common carotid artery, including high origin, rare absence, low bifurcation & also anomolous origins of common carotid artery are very common. Knowledge of carotid bifurcation is important for vascular surgical procedures, such as carotid endarterectomy or radical neck dissection, catheterization and aneurysms 1 . The aim of this study was to describe the level of common carotid artery bifurcation. 50 adult cadavers were dissected and variation in pattern of common carotid artery bifurcation were noted. During radical neck surgeries, the common carotid arteries are important landmarks, defining the plane of the dissection .Evaluation of the carotid bifurcation level can be done with non invasive techniques and external anatomical landmarks can be clinically useful in predicting the bifurcation level of the carotid artery. Accurate level of bifurcation can be devised by dissection method in nonliving. Increase variations in the branching patterns may increase the risk of vascular accidents during surgical procedures in the neck and also angiographic aberrations 3
