Vertebral artery dissection

Vertebral artery dissection is a condition that involves a tear in the lining of the vertebral artery, one of the major arteries that supply blood to the brain.

This tear can cause blood to enter the arterial wall, creating a hematoma that may narrow or block the artery, leading to reduced blood flow to the brain.

As a result, this condition can lead to a stroke, which is a serious medical emergency.

Vertebral artery dissection can occur spontaneously or as a result of trauma, such as a neck injury or sudden neck movement.

It can affect individuals of any age, though it is more common in younger and middle-aged adults.

Symptoms may include severe headache, neck pain, dizziness, vision problems, or difficulty speaking, and they can vary widely depending on the extent of the dissection and the areas of the brain affected.

Diagnosis is typically made using imaging studies such as magnetic resonance imaging (MRI) or computed tomography (CT) angiography, which can visualize the dissection and assess its impact on blood flow.

Management of the condition may involve antithrombotic therapy to prevent stroke, and in some cases, surgical intervention may be necessary.

Understanding vertebral artery dissection is crucial as early detection and treatment can significantly impact outcomes.

Patients are advised to seek immediate medical attention if they experience symptoms suggestive of this condition.
