Syndrome of Extracranial Obstruction of the Internal Carotid Artery (Syndromum Obturationis Extracranialis Arteriae Carotidis Internae)

Syndrome of Extracranial Obstruction of the Internal Carotid Artery (Syndromum Obturationis Extracranialis Arteriae Carotidis Internae) is a condition in which a combination of opto-hemiplegic syndrome occurs with a weakening of the pulsation of the carotid artery and a decrease in pressure in the central retinal artery. This syndrome is observed on the side of the extracranial obstruction of the internal carotid artery.

Optical-hemiplegic syndrome manifests itself in the form of hemiplegia, that is, paralysis of half the body, and visual impairment in the form of a narrowing of the visual field and a decrease in visual acuity. The weakening of the pulsation of the carotid artery is associated with a decrease in blood flow in this artery, which can lead to brain hypoxia. Decreased pressure in the central retinal artery can lead to impaired visual function.

The cause of Extracranial Internal Carotid Artery Occlusion Syndrome may be stenosis or occlusion of the internal carotid artery. A stenosis is a bottleneck in an artery that narrows the lumen and reduces blood flow. Occlusion is the complete cessation of blood flow through an artery. These conditions may occur due to atherosclerosis, thrombosis, embolism, congenital arterial abnormalities, or trauma.

To diagnose Extracranial Internal Carotid Artery Occlusion Syndrome, various examination methods are used, such as ultrasound, angiography, computed tomography and magnetic resonance angiography. Treatment may include conservative methods such as anticoagulants and antiplatelet agents, and surgical methods such as endarterectomy and stenting.

Extracranial Internal Carotid Artery Occlusion Syndrome is a serious condition that can cause visual and motor impairment. Therefore, it is important to seek medical help at the first signs of this syndrome in order to begin treatment in a timely manner and prevent possible complications.



Syndrome of extracranial occlusion of the internal carotid artery (SYO) is an independent intracranial transient disorder of cerebral circulation. Includes a combination on the side with impaired blood flow through the main vessels of the brain and suppression of vital signs of neurological
