Stroke & Vascular Disorders
Spontaneous carotid and vertebral artery dissection
Cerebral artery dissection is the most common cause of stroke in young adults. The most common clinical features of extracranial carotid dissection include ipsilateral headache or neck pain, Horner syndrome, and cerebral or retinal ischemia. An estimated 50% of cases develop stroke and 30% present with transient ischemic attack from hemodynamic compromise of the distal vasculature due to luminal narrowing, or by distal embolism due to thrombotic fragments that communicate with the lumen of the dissected vessel.
