carotid bifurcation

carotid bifurcation

[TA]
the division of the common carotid artery into internal and external carotid arteries; it occurs at the level of the superior border of the thyroid cartilages (vertebral level C4), The carotid body and sinus occur in relation to the carotid bifurcation.

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).
