“…17 Pratt-Thomas and Berger 16 reported that their patients had, at postmortem examination, an increased range of movement at the atlantoaxial joint, as judged by the pathologist. Vertebral ligament laxity has been recently proposed as a contributing condition in stretch syncope, a clinical syndrome with complete loss of consciousness during stretching with the neck hyperextended.…”

Background. Vertebrobasilar ischemic strokes may occur after chiropractic manipulation of the cervical spine or, less often, after spontaneous and abrupt head movement.Summary of Review. We describe three such cases of vertebrobasilar ischemic strokes and review 36 other reported cases.Conclusions. We give evidence that 1) the population at risk cannot be identified a priori in the vast majority of cases; 2) symptoms may develop after many uneventful manipulations; 3) clinical syndromes consist of occipital lobe (5%), cerebellar (8%), locked-in (8%), Wallenberg's (28%), other brain stem (49%), and unclassifiable (2%); 4) mortality or very severe long-term impairment occurs in 28% of cases; 5) the development of transient neurological symptoms during previous manipulations, the presence of known or suspected ligament laxity, and, if known, the presence of a vertebral artery terminating in posterior inferior cerebellar artery should always contraindicate any chiropractic neck maneuver, and 6) the pathogenetic mechanism involves vertebral artery dissection at the atlantoaxial joint with intimal tear, intramural bleeding, or pseudoaneurysm that can lead to thrombosis or embolism.

Abstract:Vertebral Artery Occlusion Following Hyperextension and Rotation of the Head• This is a case report of a lateral medullary syndrome of Wallenberg following occlusion of one vertebral artery and stenosis of the opposite artery precipitated by combined motion of hyperextension, rotation, and lateral flexion of the head within physiological limits. Sufficient duration of such head position appeared to initiate thrombus formation following stenosis or occlusion of the vertebral artery at the level of the atlanto-occipital joint. Propagation of this thrombus obstructed the posterior inferior cerebellar artery causing infarction of the lateral medullary region. The pathogenesis of this mechanism is discussed. Additional Key WordsWallenberg syndrome vertebral artery thrombosis posterior inferior cerebellar artery atlanto-occipital joint However, the mechanism of arterial occlusion, thrombosis, and infarction has not been clarified from postmortem or clinical findings. 6This article presents a description of a lateral medullary syndrome following sustained physiological hyperextension, rotation, and lateral flexion movements of the head for a period of several hours. The angiographical survey demonstrated complete obstruction of the right vertebral artery associated with severe stenosis of the vertebral artery on the left. The clinical course and angiographical abnormalities provide an interesting sequence of events which suggest a probable mechanism of progression for this type of vascular occlusion. Case ReportA 43-year-old left-handed male draft designer experienced occasional nonvertiginous dizziness for two years. On March 21, 1974, he painted the ceilings of two rooms in his home, beginning in the early morning and finishing in the late afternoon. While painting, he used a roller or brush in his left hand. Therefore, his head was maintained in hyperextension, rotated to the left, and tilted to the right. Occasionally he used his right hand while his head remained hyperextended, rotated to the right, and tilted to the left. During that afternoon, he noted occasional dizziness as he used his right hand. The remainder of the day was not unusual and he was in no particular distress. The next morning, From the Division of Neurosurgery, Department of Neurology, University of Iowa College of Medicine, Iowa City, Iowa 52242. however, on March 22, 1974, he experienced an abrupt onset of severe headache, unsteadiness, numbness of the right side of his face, difficulty swallowing, and loss of taste on the right side of the tongue. As he attempted to climb into bed, he fell to the floor with marked loss of balance, but noted no change in level of consciousness. On March 23rd he was admitted to a local hospital where his ataxia and headache increased gradually. On admission to University of Iowa Hospitals on March 28th, examination revealed an alert and well-oriented man with a blood pressure of 140/80 mm Hg. The cranial nerve examination revealed absence of corneal reflex, and marked impairment of sensation to touch ...
