ABSTRACT
Infarction mechanisms Three mechanisms determine brain infarction in carotid artery disease. The most frequent is atheroembolism, followed by distal perfusion failure, and distal thrombus formation due to blocked blood flow. 19 Carotid occlusion is less frequent. 12,20 All of them produce some of the following syndromes: transient ischemic attack (TIA), stroke, and progressive neurological defects.
