A Statement on Cervical Manipulation and Dissections

VAD

The American Heart Association and the American Stroke Association recently published in the journal Stroke a thorough analysis of the evidence for an association between cervical manipulative therapy (CMT) and both vertebral artery dissection (VAD) and internal carotid artery dissection (ICAD). The full article is online: “Cervical Arterial Dissections and Association With Cervical Manipulative Therapy: A Statement for Healthcare Professionals From the American Heart Association/American Stroke Association.” For background, an arterial dissection is essentially a tear in the inner lining of the artery. This tear disrupts the normal flow of blood, and also causes platelets to gather at the site of injury. This can result in a blood clot at the site of the dissection. This blood clot can block flow through the artery, or it can break off and lodge downstream, blocking flow at that point. Dissections, therefore, can result in a stroke (a lack of blood flow to a portion of the brain causing damage). There are four arteries in the neck that bring blood from the heart to the brain, two carotid arteries in the front, and two vertebral arteries in the back. A dissection in one or more of these arteries is associated with 2% of all strokes, but with 8-25% of strokes in patients <45 years old. This is mostly because strokes associated with processes like atherosclerosis are much less common in the younger population. Arterial dissections are classified as either spontaneous or traumatic. Trauma can be either severe, such as whiplash injury from a car accident, or subtle, such as from yoga or simply turning one’s neck to look past the shoulder. (more…)
