Thromboembolic Common Carotid Arteries Stroke, often called a carotid artery stroke, is a serious medical condition that occurs when there is a blockage in one of the carotid arteries, leading to the brain. This blockage, typically caused by a blood clot, can result in various types of strokes, each with its own set of causes, symptoms, diagnostic tests, treatments, medications, and, in some cases, surgical options. In this article, we will explain this complex condition in plain and easy-to-understand language, providing you with essential information to understand, identify, and manage carotid artery strokes effectively.
Types of Carotid Artery Strokes:
- Ischemic Stroke: Definition: An ischemic stroke occurs when a blood clot or other debris blocks blood flow to the brain, starving it of oxygen.
- Embolic Stroke: Definition: Embolic strokes are a subset of ischemic strokes where a clot travels from another part of the body, often the heart, to block a carotid artery.
Common Causes of Carotid Artery Strokes:
- Atherosclerosis: Definition: Atherosclerosis is the buildup of fatty deposits in the carotid arteries, narrowing them and increasing the risk of clots.
