      COMMON CAROTID ARTERY BIFURCATION GEOMETRY ON CT ANGIOGRAPHY (Abstract): Background and Purpose: Each individual’s vascular anatomy variations may contribute to the acceleration of atherosclerotic plaque formation. Given that most pathological changes occur near the terminal bifurcation of the common carotid artery, we decided to test if we encounter inter-individual variability of geometric parameters in healthy adult patients. Method: Disease-free carotid computed tomography angiographies were selected from 40 patiens. Identifying the height of the common carotid bifurcation was done in relation to the cervical vertebraes. The angle between the common carotid artery - internal carotid artery and the bifurcation angle were measured in a robust way to attempt to make the measurement straighforward and, as such, easily reproductible. Results: The majority of carotid bifurcations were demonstrated near the C4 cervical vertebrae (66,25%). The internal carotid angle recorded was on average 157 ± 12°, and the bifurcation angle was 42 ± 10°. Conclusions: Moderate interindividual variations regarding carotid bifurcation geometry in our adult population suggests that, if a geometric risk for atherosclerosis will eventually be considerate, its early detection could be challenging.
