"Distal stump" of the internal carotid artery with ascending pharyngeal artery collateralisation. A potential source for further embolic ischemia

Neuroradiology. 1987;29(1):81-3. doi: 10.1007/BF00341046.

Abstract

In 2 patients, clinically exhibiting recent amaurosis fugax and small cortical infarction, carotid occlusion had been shown by means of doppler ultrasound. IA-DSA showed a collateral circulation within the distal carotid artery in the base of the skull via the ascending pharyngeal artery. The slowly perfused stump of a distal carotid artery is supposed to be a potential source of emboli into the retinal or intracranial territories.
