During cervical artery dissection, which arteries are most likely to be involved?

• A. Internal jugular and subclavian arteries
• B. Vertebrobasilar and internal carotid arteries
• C. Carotid and basilar arteries
• D. Aorta and renal arteries

Answer: (B)

Cervical artery dissection is a condition that involves a tear in the artery wall, often leading to complications such as ischemia or stroke. The two main types of arteries commonly affected in cervical artery dissection are the vertebrobasilar arteries and the internal carotid arteries. The vertebrobasilar system supplies blood to the posterior circulation of the brain, including vital areas responsible for functions such as balance, coordination, and vital signs. The internal carotid arteries primarily supply blood to the anterior circulation, which is essential for cognitive function and consciousness. When dissection occurs in these arteries, it can disrupt blood flow and lead to serious neurological outcomes, such as transient ischemic attacks or strokes. Understanding the relevance of these arteries is critical in the clinical assessment of a patient who presents with signs suggestive of cervical artery dissection, such as neck pain, headache, or neurological deficits. Therefore, the involvement of both the vertebrobasilar and internal carotid arteries in cervical artery dissection highlights the potential severity of this condition.
