[Spontaneous dissection and stenosis of the vertebral artery].
The case of a 21-year-old female patient with neck pain and brain stem symptomatology after appendectomy is reported. Duplex sonographic findings were compatible with right vertebral artery dissection and occlusion of the vessel. Angiography confirmed the diagnosis. The patient recovered within weeks and was free of symptoms 6 months after the acute episode. Dissection of the vertebral artery can occur with or without minor trauma. Associations with fibromuscular dysplasia, arterial hypertension and the use of oral contraceptives have been reported. As in our own patient, dissection can appear without any vessel pathology or risk situation. The most dangerous complication of the disease is rupture of the adventitia with subarachnoid hemorrhage. Without this complication, prognosis of vertebral artery dissection is favourable with complete recovery within weeks. Clinical findings, diagnostic procedure and therapy are discussed.
