[Clinical aspects, pathogenesis and treatment of neurovascular spastic torticollis].

The authors describe the clinical picture and treatment of neurovascular spastic torticollis (NVST) with special reference to 20 patients with ST, who underwent microvascular decompression of the accessory nerves. Postural attenuation of ST served as a criterion for the screening of the patients. The authors describe the results of clinico-anatomic correlations, attesting to the diverse neurological picture of NVST and to the presence of correlations between the nystagmus in ST and compression of nerve XI of the posterior connective artery as well as between facial hyperkineses in ST patients and compression of the accessory nerves by the pathologically involuted vertebral and posteroinferior cerebellar arteries.
