Relationship between intima-media thickness in the common carotid artery and atherosclerosis in the
carotid bifurcation. Stroke 1998;29(27):1378-82.
Variation in the
carotid bifurcation geometry of young versus older adults: implications for geometric risk of atherosclerosis.
Similar sex differences have been reported in the anatomy of common
carotid bifurcation (Krejza et al., 2006) and intracranial arteries (Lindekleiv et al., 2010).
Most common source of embolism is the
carotid bifurcation, but may arise from the aortic arch, common carotid, internal carotid, vertebral, and basilar artery also.
A computerised tomographic angiogram (CTA) was performed and revealed a 6 cm highly vascular tumour splaying the
carotid bifurcation with near total encasement of the external carotid artery (ECA) and partial encasement of the internal carotid artery (ICA).
Anticoagulation is preferable for lesions not amenable to surgery, such as intracranial lesions or those near the
carotid bifurcation.
The
carotid bifurcation tends to develop atherosclerotic stenosis, which might interfere with cerebral blood supply and can cause coma, hemodynamic disturbance, stroke, and even death.
[4] simulated blood flows in both concentrically and eccentrically stenosed
carotid bifurcation models to study geometrical effects on flow patterns.
Note the occlusion of the left internal carotid artery, starting at the level of the common
carotid bifurcation (a), in the neck (b), and in the carotid canal (c).
[4] had calculated blood rheology marker for bulk flow in models of
carotid bifurcation. Newtonian rheology was hold true for bulk flow metrics and found to influence wall shear stress at different levels of geometry.
The anterior circulation consists of internal carotid arteries, which originate from the
carotid bifurcation and are divided into anterior cerebral and middle cerebral arteries.
A contrast-enhanced multidetector computed tomography angiography (MDCTA) confirmed the lesion in the right
carotid bifurcation and showed a proximal critical stenosis of the innominate and left carotid artery emerging from a BAA with a concentric vulnerable plaque of the bovine common trunk (Figure 1).
