Carotid and vertebral artery dissection is a rare but important cause of stroke, accounting for roughly 20% of strokes in patients under the age of 45.

Moreover, up to half of patients with dissection have been found to exhibit connective tissue abnormalities upon microscopic analysis of skin biopsies.
