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.

Bilateral External Carotid Artery Aneurysms
Vascular, 2004A 60-year-old female was found on a physical examination to have bilateral palpable pulsatile neck masses. She denied local pain, cranial nerve compressive symptoms, or symptoms of cerebral ischemia. Duplex ultrasonography demonstrated bilateral 1.5 x 2.2 cm external carotid artery aneurysms.

Mycotic aneurysm of the external carotid artery
The Journal of Laryngology & Otology, 1998AbstractMycotic aneurysms of the extracranial carotid arteries are extremely rare. A case is reported of a false aneurysm of the left external carotid artery. This developed secondary to cervical lymphadenitis which did not settle with high dose antibiotic therapy.

Embolization in the External Carotid Artery
Journal of Vascular and Interventional Radiology, 2006The technical skill set of peripheral interventional radiologists is well-suited to the performance of most transcatheter embolization procedures in the external carotid artery (ECA). These procedures center in large part on hypervascular tumors, epistaxis, and trauma.

External carotid artery stenting in symptomatic internal carotid artery occlusion
Journal of Clinical Neuroscience, 2020We report the case of a patient with an anterior ischemic stroke due to tandem occlusion of the left M2 segment and ipsilateral internal carotid artery (ICA), with concomitant severe stenosis of the ipsilateral external carotid artery (ECA) and contralateral ICA, and moderate stenosis of the left vertebral artery (VA); as thrombectomy was not possible,

Tentorial arteries arising from the external carotid artery [PDF]
Neuroradiology, 1978 Two 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.

The external carotid artery (ECA) gives off various branches supplying musclocutaneous organs, visceral organs (pharynx, oral cavity, larynx, and thyroid), cranial nerves, facial and skull bones, and dura matter. It communicates to the cerebral arteries and ophthalmic artery via various potential anastomoses.

Congenital External Carotid Artery Aneurysm
Annals of Vascular Surgery, 2010An 8-month-old child presented with a right pulsatile neck mass. The tumor's rapid increase in size and respiratory problems prompted image evaluation. An external carotid artery aneurysm was found, which was compressing other neck structures. The patient underwent aneurysm resection and ligation at its insertion on the common carotid artery.

Arteriovenous Fistula of External Carotid Artery
Archives of Otolaryngology - Head and Neck Surgery, 1968ARTERIOVENOUS fistulas of the face and neck are rare clinical entities but do occur either as congenital disorders or as the result of trauma. Flynn and Mulder 1 define the congenital arteriovenous fistula as a nontraumatic vascular abnormality in which the arterial blood passes into the venous system without traversing the capillary bed.

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.
