Carotid artery dissection refers to a condition where a tear occurs in the inner lining of the carotid artery, one of the major blood vessels in the neck that supplies blood to the brain. This tear can lead to the formation of a blood clot, which may partially or completely block the artery, impeding blood flow to the brain.
Carotid artery dissection can be caused by trauma, such as a sudden neck movement or injury, or it may occur spontaneously without any apparent cause. Common symptoms include sudden and severe headache, neck pain, dizziness, vision problems, and difficulty speaking or understanding speech.
Diagnosis of carotid artery dissection involves medical imaging techniques like ultrasound, CT scan, or MRI. Treatment options depend on the severity of the dissection and may include medication to prevent blood clots, surgery to repair the artery, or endovascular procedures to open up the blocked artery.
Early detection and prompt treatment are crucial in managing carotid artery dissection to prevent potential complications like stroke or transient ischemic attack (TIA). If you experience any symptoms suggestive of carotid artery dissection, it is important to seek immediate medical attention.
