Carotid and Vertebral Artery Dissections.

Carotid and vertebral artery dissections are an important cause of stroke in younger patients that can present a diagnostic challenge. Symptoms can range from subtle neck pain and headache to a clear stroke syndrome. Carotid and vertebral artery dissections, referred to as cervical artery dissections, are often associated with a traumatic mechanism of varying severity, and screening has been incorporated into major trauma guidelines. Diagnosis is achieved through vessel imaging, most commonly computed tomography angiography or magnetic resonance angiography. Treatment with antiplatelet or antithrombotic agents depends on individual patient risk factors and is typically continued for 3 to 6 months.
