Developing Pulsatile Flow in the Internal Carotid Artery.

Unrecordable pulsatile ocular blood flow may signify severe stenosis of the ipsilateral internal carotid artery.

AIM To examine the relation between stenosis of the internal carotid artery (ICA) and pulsatile ocular blood flow (POBF). METHODS In 57 eyes of 30 patients who were referred for Doppler ultrasound examination of the ICA we measured POBF and analysed the correlation with degree of ipsilateral ICA stenosis. RESULTS There was a significant negative correlation between POBF and ipsilateral ICA ...

Pulsatile Tinnitus Arising from Aberrant Internal Carotid Artery at Nasopharynx

Pulsatile tinnitus arising from an aberrant internal carotid artery at the level of the nasopharynx is rarely found. We present a case of a 74-year-old woman complaining of pulsatile tinnitus in the right ear. The tinnitus was not audible by auscultation. Endoscopic examination revealed pulsating swelling of the nasopharyngeal wall on the right side. Computed tomography angiography of the head ...

A Penetrating Pellet Jeopardizing Internal Carotid Artery

SCIENTIFIC REPORT Unrecordable pulsatile ocular blood flow may signify severe stenosis of the ipsilateral internal carotid artery

Aim: To examine the relation between stenosis of the internal carotid artery (ICA) and pulsatile ocular blood flow (POBF).

Pulsatile tinnitus from reversal of flow in an aberrant occipital artery: resolved after carotid artery stenting.

Carotid artery stent placement, performed for correction of an asymptomatic severe stenosis, leads to the resolution of persistent and troublesome pulsatile tinnitus. Tinnitus has been reported as a consequence of severe carotid stenoses on previous occasions. This case highlights how an aberrant occipital artery originating above a carotid artery stenosis can result in flow reversal and be a m...
