Congenital internal carotid artery hypoplasia

Bilateral hypoplasia of the internal carotid artery

Agenesis and hypoplasia of the internal carotid artery (ICA) are rare congenital anomalies, occurring in less than 0.01% of the population. We report a rare case of bilateral hypoplasia of the ICA in a patient with post-traumatic subarachnoid hemorrhage. We describe the embryological development of the cerebral vasculature and present a review of literature.

Congenital Hypoplasia of Bilateral Internal Carotid Artery with Migraine-Like Headache with Aura

To the Editor: A 36‐year‐old man with intermittent migraine‐like headache with aura for 20 years underwent cerebrovascular computed tomography angiography (CTA) revealing very small calibers of bilateral internal carotid arteries (ICAs) in other hospital. He was admitted to our hospital for further examination several days later. He had no vascular risk factors, and no family history of atheros...

Congenital Horner Syndrome with Heterochromia Iridis Associated with Ipsilateral Internal Carotid Artery Hypoplasia

BACKGROUND Horner syndrome (HS), also known as Claude-Bernard-Horner syndrome or oculosympathetic palsy, comprises ipsilateral ptosis, miosis, and facial anhidrosis. CASE REPORT We report herein the case of a 67-year-old man who presented with congenital HS associated with ipsilateral hypoplasia of the internal carotid artery (ICA), as revealed by heterochromia iridis and confirmed by compute...

Intracranial dissection and extracranial hypoplasia of the internal carotid artery.

issection of the intracranial portion of the internal carotid artery (ICA) is an uncommon cause of stroke or transient ischemic attack (TIA). Congenital anomalies of the ICA have been rarely associated with cerebral ischemia. However, unilateral ICA hypoplasia can be frequently associated with intracranial arterial anomalies and altered hemodynamics.1 We describe the case of a woman who had sud...
