Carotid artery dissection
Carotid dissection is a serious condition in which a tear forms in one of the two main carotid in the neck, allowing blood to enter the artery wall and separate its layers (dissection). This separation can lead to the formation of a blood clot, narrowing of the artery, and restricted blood flow to the brain, potentially resulting in . Symptoms vary depending on the extent and location of the dissection and may include a sudden, severe headache, neck or facial pain, vision changes, a drooping eyelid, and stroke-like symptoms such as weakness or numbness on one side of the body, difficulty speaking, or loss of coordination.
