Overview
Vertebral artery dissection is the development of dissection (a flap-like tear) in the vertebral artery. It is commonly associated with physical trauma but may also develop spontaneously. It is a major cause of stroke in young people.
Presentation
Typical features are pain in the neck associated with stroke-like symptoms of the "posterior circulation": cranial nerve palsies, ataxia, and cortical visual loss.[1] It can also cause subarachnoid hemorrhage (bleeding into the area around the brain); dissecting aneurysms of the vertebral artery represent about 4% of all aneurysms.[2]
Incidence
The annual incidence is about 1 per 100,000 in America and 1.5 per 100,000 in France.[2]

| Class I |
| "1. Noninvasive imaging by CTA or MRA for detection of vertebral artery disease should be part of the initial evaluation of patients with neurological symptoms referable to the posterior circulation and those with subclavian steal syndrome. (Level of Evidence: C) " |
| "2. Patients with asymptomatic bilateral carotid occlusions or unilateral carotid artery occlusion and incomplete circle of Willis should undergo noninvasive imaging for detection of vertebral artery obstructive disease. (Level of Evidence: C) " |
| "3. In patients whose symptoms suggest posterior cerebral or cerebellar ischemia, MRA or CTA is recommended rather than ultrasound imaging for evaluation of the vertebral arteries. (Level of Evidence: C) " |
| Class IIa |
| "1. In patients with symptoms of posterior cerebral or cerebellar ischemia, serial noninvasive imaging of the extracranial vertebral arteries is reasonable to assess the progression of atherosclerotic disease and exclude the development of new lesions. (Level of Evidence: C) " |
| "2. In patients with posterior cerebral or cerebellar ischemic symptoms who may be candidates for revascularization, catheter-based contrast angiography can be useful to define vertebral artery pathoanatomy when noninvasive imaging fails to define the location or severity of stenosis. (Level of Evidence: C) " |
| "3. In patients who have undergone vertebral artery revascularization, serial noninvasive imaging of the extracranial vertebral arteries is reasonable at intervals similar to those for carotid revascularization. (Level of Evidence: C) " |
