Ascending pharyngeal collaterals between the external carotid artery and the occluded internal carotid artery.
نویسنده
چکیده
A 68-year-old man presented with occlusion of the internal carotid artery (ICA) manifesting as a 6-month history of progressive sensory and motor disturbance of the left lower limb. Angiography clearly demonstrated a collateral arterial network between the ICA and external carotid artery (ECA) through the vidian artery, a small branch of both the ICA and ECA. The vidian artery may form an unusual but important ECA-ICA collateral pathway in patients with occlusive lesion of the ICA. Neurol Med Chir (Tokyo) 46, February, 2006 Letter to the Editor

Reconstitution of obstructed ICA via collaterals.
Recently we encountered an unusual case in which a left internal carotid artery (ICA), occluded at its origin by atherosclerosis, was reconstituted in its cervical position by small anastomotic branches of the ascending pharyngeal artery. An initial angiogram demonstrated apparent occlusion of the left ICA at its origin. However, on late films, there was opacification with antegrade flow of the...
متن کاملCollateral circulation via the ascending pharyngeal artery arising from the internal carotid artery.
Artery Arising from the Internal Carotid Artery I read with interest the article by Chan et al. They stated that there was a rare congenital anastomosis between the vertebral artery (VA) and internal carotid artery (ICA) with an absence of communication between the common carotid and cervical ICA. I, however, diagnose that there was an acquired occlusion of the ICA at its origin with a developm...
متن کاملAnatomical study of the carotid bifurcation and origin variations of the ascending pharyngeal and superior thyroid arteries.
BACKGROUND Human anatomy texts in current use have very little precise information as to the frequency of variations in the bifurcation of the common carotid artery, and a clear description of the relation between external and internal carotid arteries as well as the variation of the origin of the ascending pharyngeal and superior thyroid arteries is limited. MATERIAL AND METHODS Sixty common...
متن کاملOcclusion of the ascending pharyngeal artery during carotid artery surgery: importance and technique.
AIM In surgeries involving clamping, opening and repairing the carotid artery such as carotid endarterectomy (CEA) and proximal anastomosis at radial artery (RA) grafting, back-bleeding, often due to insufficient occlusion of the ascending pharyngeal artery (APA), must be avoided. In 96% of cases the APA originates at the dorsal side of the external carotid artery, while in 2% each it arises at...
متن کاملAbnormal Origin of Superior Laryngeal Artery and Its Clinical Significance: A Case Report
Superior laryngeal artery (SLA) is one of the main branches of the superior thyroid artery that its main function is to supply blood to the larynx. This artery is accompanied by the internal branch of superior laryngeal nerve; this relation has anatomical and surgical significance. In this paper, a case of anomalous origin of the superior laryngeal artery is reported. Abnormal origin of SLA fro...
