A ruptured anterior communicating artery aneurysm associated with internal carotid artery agenesis and a middle cerebral artery anomaly [PDF]

Journal of Clinical Neuroscience, 2009
Agenesis of the internal carotid artery associated with an anomalous middle cerebral artery originating from the contralateral internal carotid artery is rare. We report a patient with agenesis of the internal carotid artery presented with a subarachnoid

Carotid Artery Tortuosity and Internal Carotid Artery Plaque Composition

Clinical Neuroradiology, 2023
Little is known about the association between carotid artery tortuosity and internal carotid artery atherosclerosis. This study sought to evaluate the associations between various types of arterial tortuosity and vulnerable plaque components on magnetic resonance angiography (MRA).A retrospective review was completed of 102 patients who had undergone ...

Hypoplasia of the carotid arteries is a rare congenital anomaly which when clinically symptomatic presents as cerebral ischemia or hemorrhage. Patients with this anomaly commonly have associated variations of the circle of Willis, an increased incidence of intracranial aneurysms and extensive networks of collateral vessels to accommodate the diminished
