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 ischemic stroke in young people.
Epdidemiology and Demographics
The annual incidence is about 1 per 100,000 in America and 1.5 per 100,000 in France.[1]
Diagnosis
Symptoms
Typical features are pain in the neck associated with stroke-like symptoms of the "posterior circulation": cranial nerve palsies, ataxia, and cortical visual loss.[2] 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.[1]

Class I |
"1. Contrast-enhanced CTA, MRA, and catheter-based contrast angiography are useful for diagnosis of cervical artery dissection. (Level of Evidence: C) " |
Class IIa |
"1. Antithrombotic treatment with either an anticoagulant (heparin, low-molecular-weight heparin, or warfarin) or a platelet inhibitor (aspirin, clopidogrel, or the combination of extended-release dipyridamole plus aspirin) for at least 3 to 6 months is reasonable for patients with extracranial carotid or vertebral arterial dissection associated with ischemic stroke or TIA. (Level of Evidence: B) " |
Class IIb |
"1. Carotid angioplasty and stenting might be considered when ischemic neurological symptoms have not responded to antithrombotic therapy after acute carotid dissection. (Level of Evidence: C) " |
"2. The safety and effectiveness of pharmacological therapy with a beta-adrenergic antagonist, angiotensin inhibitor, or nondihydropyridine calcium channel antagonist (verapamil or diltiazem) to lower blood pressure to the normal range and reduce arterial wall stress are not well established. (Level of Evidence: C) " |
