Dissection of the extracranial carotid or vertebral arteries can result in cerebral infarction. The injury may produce hemorrhage into the vessel wall leading to occlusion of the vessel or possible thrombus formation with subsequent embolization. In comparison to atherosclerotic stroke, the patients who suffer carotid or vertebral artery dissection tend to be younger in age and the injury may occur spontaneously or in association with trauma. Several case reports have suggested a link between vertebral artery dissection and chiropractic manipulation of the neck. In this new study, Rothwell and colleagues conducted a recent population-based, nested, case-control study to examine the possible association.

The final paragraph of the referenced article-
An association was found between recent chiropractic visits and the risk of vertebrobasilar accidents in patients under 45 years of age. The patients were 5 times more likely than controls to have visited a chiropractor in the previous week and to have had 3 or more cervical chiropractic visits in the previous month. No significant associations were discovered for the patients aged 45 years and older. Although the results demonstrated an association, further investigation is required to provide conclusive evidence.
Now compare this to the number of people who die every year as the result of using common anti-inflammatory drugs, or against the number of people who die as a result of malpractice.
