Anomalous course of the external carotid artery
Anatomical Science International, 2015The course and the branching patterns of the external carotid artery were investigated macroscopically in a total of 550 bodies or 1100 head sides of Japanese subjects, donated for student dissection at Kumamoto University from 1994 to 2014. With the exception of 14 head sides, the external carotid arteries running between the posterior belly of the ...

The external carotid artery (ECA) arises from the bifurcation of the common carotid artery (CCA), usually at the level of the third and fourth cervical vertebrae. The superior thyroid artery (STA) can arise from a common trunk with the lingual artery as the thyrolingual trunk, or with the lingual and facial arteries as the thyrolinguofacial trunk ...

Duplex US of the External Carotid Artery
Acta Radiologica, 1996The ratio between the systolic peak velocities of the internal and common carotid arteries (vpICA/vpCCA), vpICA and grey-scale imaging measurement are generally used to evaluate internal carotid stenosis against known flow criteria in order to differentiate non-significant from significant stenosis.

The external carotid artery (ECA) arises from the common carotid bifurcation at the C4 vertebral level. A more proximal or distal origin can occur. Variants of the level of the carotid bifurcation are described in Chap. 2. These variants also involve indirectly the origin of the ECA. The ECA may originate directly from the aortic arch.

Tentorial arteries arising from the external carotid artery
Neuroradiology, 1978Two cases illustrating an unusual connexion between the middle meningeal artery and tentorial branches, normally arising from the siphon, are reported. The significance of this anastomosis is discussed.
