Carotid Vein Occulation Symptoms
Carotid artery occlusion is an extremely rare condition that occurs when blood flow to the brain is blocked by a clot or other blockage. Learn more about carotid artery occlusions symptoms, causes, and treatments.
Carotid artery occlude (CAO) is a very rare condition in which there is a complete or near-complete obstruction of the internal carotid artery. CAO is usually caused by a thrombus (blood clot), although other types of lesions can also cause this problem.
What Is Carotid Artery Occlusion?
A common symptom of carotid artery occlusions is sudden onset of severe headache with no known cause. Other symptoms include loss of vision, weakness, numbness, tinnitus, vertigo, nausea, vomiting, confusion, speech difficulties, and seizures.
Carotid Artery Blockages Are Rare But Dangerous
Carotid artery blockages are very rare, occurring in less than 1% of people who have had a stroke. However, they are dangerous because they can lead to permanent damage to the brain. In fact, carotid artery blockages account for approximately 5% of strokes.
Carotid Arteries Supply Blood To The Brain
The carotid arteries supply blood to the brain. These vessels originate at the base of the neck and run down the sides of the head. There are two main carotid arteries, one on each side of the body. Each carotid artery has three branches: internal carotid artery (ICA), external carotid artery (ECA) and common carotid artery (CCA).
Carotid Artey Occlusion Symptoms Include Headaches And Dizziness
Carotid artery stenosis is a narrowing of the lumen of the carotid artery. This narrowing reduces blood flow through the vessel. If the narrowing is severe enough, it will cause symptoms such as headaches, dizziness, vision changes, numbness, tingling, weakness, speech difficulties, memory loss, confusion, and even paralysis.
Carotid Artye Occlusion Causes May Be Due To A Stroke Or Other Health Issues
Carotid artery thrombosis (also known as carotid artery occulsion) is a medical emergency that requires immediate treatment. It is caused by a blood clot forming inside one of the arteries supplying oxygenated blood to the brain. The most common symptom of carotid artery thrombus is sudden onset of headache, neck pain, and/or jaw pain.
