Carotid Artery Diseases
| Definition: |
Diseases of the common, internal, and external carotid arteries. ATHEROSCLEROSIS and trauma are relatively frequent causes of carotid artery pathology. |

Carotid Artery Diseases Categories.

Carotid Artery Injuries - Blunt and penetrating traumatic injuries of the common, internal, or external carotid arteries which may result from CRANIOCEREBRAL TRAUMA; THORACIC INJURIES; and NECK INJURIES. Damage to the artery may lead to CAROTID ARTERY THROMBOSIS; CAROTID-CAVERNOUS SINUS FISTULA; pseudoaneurysm formation; and internal carotid artery dissection (CAROTID ARTERY, INTERNAL, DISSECTION). Clinical manifestations (e.g., stroke, HORNER SYNDROME) may be immediate or delayed. (From Am J Forensic Med Pathol 1997 Sep;18(3):251-7; J Trauma 1994 Sep;37(3):473-9) |
|
Carotid Artery Thrombosis - Blood clot formation in the common, internal, or external carotid artery which may produce stenosis or occlusion of the vessel, leading to ischemia or infarction of tissue supplied by these arteries. Thrombosis of the common and internal carotid arteries may result in ISCHEMIC ATTACKS, TRANSIENT; CEREBRAL INFARCTION; or AMAUROSIS FUGAX. |
|
Carotid Stenosis - Narrowing or stricture of the internal, common, or external carotid artery, most often as a result of atherosclerotic plaque formation. Ulcerations may form in atherosclerotic plaques and induce thrombus formation. Platelet or cholesterol emboli may arise from stenotic carotid lesions and induce a transient ischemic attack (ISCHEMIC ATTACK, TRANSIENT) or CEREBROVASCULAR ACCIDENT. Emboli which travel to the eye may manifest as AMAUROSIS FUGAX (temporary blindness). (From Adams et al., Principles of Neurology, 6th ed, pp822-3) |
|
Moyamoya Disease - A chronic cerebral vasculopathy primarily occurring in childhood and characterized by slowly progressive carotid artery narrowing and occlusion at the base of the brain. An extensive network of anastomoses forms between branches of the carotid arteries, resulting in a characteristic angiographic appearance. The condition may be idiopathic (classic moyamoya disease) or occur in association with ANEMIA, SICKLE CELL; DOWN SYNDROME; CRANIOCEREBRAL TRAUMA; RADIOTHERAPY induced arterial injury; NEUROFIBROMATOSIS; and other diseases. Clinical manifestations include hemiparesis, headache, seizures, and delayed mental development. In older individuals, this disease may present as SUBARACHNOID HEMORRHAGE. (From Adams et al., Principles of Neurology, 6th ed, p831; Clin Neurol Neurosurg 1997 Oct;99 Suppl 2:S36-8) |
