title: Vertebral artery angioplasty in patients younger than 55 years: long-term follow-up.
abstract: Since 1964 we have performed 136 vertebral artery reconstructions representing 4% of all operations on extracranial cerebral arteries by our staff. Fifteen of our patients were under age 55 years and had symptoms of dizziness, bilateral visual disturbances, ataxia, presyncopal episodes, and occasionally localized extremity weakness. Dizziness, often severe and incapacitating, has been the most common and consistent symptom. The diagnosis of vertebral artery lesions was made using aortic arch four-vessel cerebral arteriography. Operations were performed for severely obstructing bilateral vertebral artery lesions and included only unilateral vertebral vein patch angioplasty with or without suture plication of the artery in 13 patients. Unilateral carotid vertebral bypass was performed in one patient and unilateral vertebral reimplantation to the carotid in another. Follow-up averaged 8.9 years, ranging from ten months to 20 years. Eleven of 15 patients have remained asymptomatic and without strokes. Recurrent dizziness was present in three, two of whom had vertebral arteriography showing patent vertebral reconstructions. Another had a stroke related to the anterior circulation in follow-up at nine years. Atherosclerotic obstruction of vertebral arteries does occur in patients in the preatherosclerotic age group. Even atypical symptoms suggestive of vertebrobasilar insufficiency may be associated with isolated correctable bilateral flow-impeding vertebral lesions. These symptoms warrant evaluation with cardiac neurological and cerebrovascular studies. Vertebral angioplasty relieves symptoms and the incidence of stroke during follow-up is low.
