Vertebral artery dissection has been previously reported following minor head and neck trauma. Such activities as rapid head turning, tennis, yoga, and vigorous exercise have been implicated. We report a case of vertebral artery dissection following minor neck trauma suffered in a volleyball game. The anatomy of the vertebral artery, pathophysiology of dissection, and emergency department recognition and treatment of this disorder are discussed.

An 81-year-old woman became unconsciousness after complaining of a backache, and then, an ambulance was called. She was suspected to have an aortic dissection by the emergency medical technicians and was transferred to our department. On arrival, she was in shock. Emergency cardiac ultrasound disclosed good wall motion with cardiac tamponade but no complication of aortic regurgitation. Computed tomography of the trunk revealed a type A aortic dissection with cardiac tamponade. During performance of pericardial drainage, she lapsed into cardiopulmonary arrest.

Dissecting aneurysm of the vertebral arteries following chiropractic manipulation of the spine. A thirty-five years old man had a Wallenberg Syndrome following chiropractic manipulation of the spine. Plain films and hypocycloidal tomography showed a foramen arcuale on both side. Arteriography lead to the diagnosis of dissecting aneurysm of the vertebral arteries. The favourable course point to the value of the posterior communicating arteries and the spinal artery as collateral pathways of the vertebro-basilar circulation.

A 39-year-old man presented with a pure motor stroke 9 days after cervical chiropractic manipulation. Computerised tomographic scanning showed a pontine infarct. Cerebral angiography showed changes consistent with the diagnosis of bilateral vertebral artery dissection. It is postulated that the infarct resulted from artery-to-artery embolism.

Vertebral artery dissection after neck manipulation has been well described. A case of bilateral vertebral artery dissection diagnosed with dynamic CT scanning of the neck is reported. The CT appearances and correlative angiographic and MR findings are presented.

A 29-year-old woman died from a right hemispheric infarction caused by dissection and subsequent thrombosis of the internal carotid artery after chiropractic manipulations of the neck. Pathologic study of several arteries of muscular and elastic type revealed a mediolytic arteriopathy with widespread mucoid degeneration and cystic transformation of the vessel wall caused by segmental degeneration of smooth muscle cells of the tunica media.

Vertebrobasilar-distribution stroke is a rare but sometimes severe complication of chiropractic neck manipulation. We report two patients with dissections of the vertebral arteries authenticated two and six days after the cervical manipulation. In the first case, a Wallenberg's syndrome occurred due to a dissection of the right intracranial vertebral artery; the patient was treated with anticoagulant therapy but little improvement of the disorder was noted.

A review of 4,500 angiograms yielded 11 patients with dissection of the vertebral arteries who had MRI and (in 4 patients) MR angiography (MRA) in the acute phase of stroke. One patient with incidental discovery at arteriography of asymptomatic vertebral artery dissection and two patients with acute strokes with MRI and MRA findings consistent with vertebral artery dissection were included. Dissection occurred after neck trauma or chiropractic manipulation in 4 patients and was spontaneous in 10.

Vertebral artery dissections (VADs) following a variety of minor traumatic mechanisms have been previously reported. This article reports 2 cases of VAD with delayed recognition following motor vehicle collisions (MVCs). The first VAD patient developed major neurologic abnormalities 28 hours after an MVC. The second VAD patient presented with 3 weeks of neck and head pain beginning 8 weeks after an MVC and subsequent chiropractic manipulation. The anatomy and pathophysiology of VAD are reviewed.

We analyzed the clinical course and neuroradiological findings of ten patients aged 27-46 years, with ischemic stroke secondary to vertebral artery dissection (VAD; n = 8) or internal carotid artery dissection (CAD; n = 2), all following chiropractic manipulation of the cervical spine. The following observations were made: (a) All patients had uneventful medical histories, no or only mild vascular risk factors, and no predisposing vascular lesions. (b) VAD was unilateral in five patients and bilateral in three.
