Anatomical Variation of Common Carotid Artery Bifurcation In Relation To Cervical Vertebra on CT Angiogram
Journal Title: IOSR Journal of Dental and Medical Sciences (IOSR-JDMS) - Year 2018, Vol 17, Issue 12
Abstract
Aims and objectives: To see anatomical variation of common carotid artery bifurcation in relation to cervical vertebra on CT angiogram in Indian population. Materials and methods:It was a hospital based, observational, descriptive, cross sectional study with a sample size of 200 cases during a period of 1.5yrs in the department of radiology of Seth G.S. medical college and KEM hospital Mumbai.Patients undergoing CT Angiogram covering neck vessels to brain were included in study. Results: Out of 200 patients, level of bifurcation was at the same level bilaterally in 172 patients. While in 28 patients, the level of bifurcation was different on left and right side. Out of the 200 patients, level of CCA bifurcation on right side was at C2 in 3 patients, C2-C3 in 8 patients, C3 in 96 patients, C3-C4 in 32 patients, C4 in 52 patients, C4-C5 in 6 patients, C5 in 3 patients. Out of the 200 patients, the level of CCA bifurcation on left side was at C2 in 5 patients, C2-C3 in 8 patients, C3 in 103 patients, C3-C4 in 26 patients, C4 in 47 patients, C4-C5 in 8 patients, C5 in 3 patients. In 172 patients the level of bifurcation was same. In these, the bifurcation occurred at C2 in 2 patients (1.2%), C2-C3 in 5 patients (2.9%), C3 in 91 patients (53%), C3-C4 in 24 patients (13.9%), C4 in 43 patients (24.9%), C4-C5 in 6 patients (3.5%), C5 in 1 patient (0.6%). Conclusion:The Common carotid artery and its branches are the most important vessels in the neck. These vessels are susceptible to injury during various surgical procedures, neck dissections, and orthopedic surgeries on cervical vertebra. A high common carotid artery bifurcation possesses a higher risk of being hit by intraarticular screws during orthopedic procedures on cervical vertebra.Various endovascular procedures are nowadays performed in neck masses to devascularize the tumor before complete excision .Knowledge of accurate location of carotid artery bifurcation can aid in surgical planning, in ligation of external carotid artery, intra-arterial administration of chemotherapeutic agents and radical neck dissection.
