Carotid artery thrombosis might sound like a mouthful, but it’s an important topic to understand, especially when we’re talking about stroke prevention.
What Are the Carotid Arteries?
First, let’s break it down. You have two carotid arteries, one on each side of your neck. They’re like superhighways for blood, carrying oxygen-rich blood from your heart to your brain. This blood flow is crucial because your brain needs a constant supply of oxygen to function properly.
What Happens During a Carotid Artery Thrombosis?
Imagine one of those highways getting blocked by a traffic jam. In the case of carotid artery thrombosis, that “traffic jam” is actually a blood clot that forms in the artery. This clot can severely reduce or even completely block the blood flow to your brain, which is extremely dangerous.
Why Is It Dangerous?
When your brain doesn’t get enough oxygen, brain cells start to die off. This can lead to a stroke, which can cause lasting damage to your body and mind, or even be life-threatening. Carotid artery thrombosis is one of the key causes of ischemic stroke, which is the most common type of stroke.
What Causes the Blood Clot?
Several factors can increase the risk of developing a blood clot in the carotid artery. These include:
Atherosclerosis: This is when plaque (made up of fat, cholesterol, and other substances) builds up on the artery walls, narrowing them and making it easier for clots to form.
High Blood Pressure: Constant high pressure can damage the arteries, making them more susceptible to clots.
Smoking: Chemicals in cigarettes can damage your blood vessels, leading to increased clotting.
Diabetes: This condition can lead to changes in blood vessels that make clotting more likely.
Carotid Webbing: A rare and lesser-known cause is carotid webbing, which was the cause of Sybil’s stroke. Carotid webbing is a thin, fibrous band in the carotid artery that can disrupt blood flow and increase the risk of clot formation. Although rare, carotid webbing is a significant risk factor for stroke, especially in younger individuals who might not have other traditional stroke risk factors.
