Internal carotid artery hypoplasia

Computerized Radiology, 1986
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

Internal Carotid Artery Epistaxis

Otolaryngology–Head and Neck Surgery, 1986
Epistaxis from the internal carotid artery (ICA) or bleeding from the ICA at the skull base is a rare, frightening, and difficult management problem. We present five cases, with a variety of causes—in all of which the patients survived massive hemorrhage—and suggest a protocol for management of the condition.

Aplasia of the internal carotid artery

Acta Neurochirurgica, 2003
The majority of previous reports on this rare agenesis of the internal carotid artery (ICA) have been limited to reporting upon its association with other congenital anomalies case by case. In order to collectively summarize this congenital anomaly of ICA, we have reviewed nine cases of ICA aplasia and their associated abnormalities.Nine cases of ICA ...

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 ...

Aberrant Internal Carotid Artery

Southern Medical Journal, 1994
An aberrant internal carotid artery (ICA) in the middle ear is rare. If unrecognized, it may lead to massive hemorrhage or other catastrophic results during even a minor surgical procedure of the tympanic membrane or middle ear. Recognition of this entity is particularly significant to the primary care or emergency department physician who performs ...

Pseudoaneurysm of Internal Carotid Artery

The Indian Journal of Pediatrics, 2007
Pseudoaneurysms of the extracranial Internal Carotid Artery (ICA) are rare. Here it is reported a case of posttraumatic extracranial ICA pseudoaneurysm in a three-year-old boy. The pseudoaneurysm arising from the extracranial ICA was initially diagnosed by DSA. Later on confirmed by Doppler and MRA.

Fenestration of the internal carotid artery

Surgical Neurology, 1985
Fenestration of the internal carotid artery is very rare. The authors describe two cases of fenestration at the cervical portion of the internal carotid artery that were revealed by angiography. The embryological basis and clinical significance of this anomalous condition are discussed.

THROMBOSIS OF THE INTERNAL CAROTID ARTERY

American Journal of Psychiatry, 1962
Angiography has taught us much about the symptomatology of occlusion of the internal carotid artery; it may produce no symptoms or may be followed by variable complications. Simple occlusion may produce no sequelae if the circle of Willis functions efficiently and if adequate collateral circulation is established.

Internal Carotid Artery Thrombosis

Archives of Surgery, 1958
Practitioners of medicine have long recognized the clinical entity known as "stroke," or "cerebral vascular accident." For many years the cause of the neurologic manifestations has been evident, as either hemorrhage or thrombosis. Similarly, the syndrome of internal carotid artery thrombosis and certain of its sequelae have been recognized. However, it

Internal carotid artery insufficiency

The American Journal of Surgery, 1964
Abstract This series includes forty-five patients with fifty-seven diseased internal carotid arteries. Surgery was performed on forty internal carotid arteries. Seven were explored only. Three of these were considered to have insignificant amounts of occlusive disease. Four are listed as severe disease.
