Peripheral nerve tumours in own material.

Peripheral nerve tumours are rather rare soft tissue tumours. In the present article, results of surgical treatment of the peripheral nerve tumours have been presented. Clinical material consisted of 34 patients (16 females aged 19-55 years and 18 males aged 17- 75 years). The following surgical procedures were performed: excision of the tumour without damaging the structure of fascicles - 6 cases; excision of the tumour with transsection of 1-2 fascicles - 6 cases; excision of the tumour with transsection of many fascicles - 1 case; excision of the tumour with microsurgical reconstruction of part of the nerve - 6 cases; excision of the tumour without reconstruction of any part of the nerve - 4 cases; arm amputation in 1/3 proximal - 1 case; and evacuation of the intraneural cyst with wall excision - 2 cases. The pre- and postoperative motor and sensory deficit have been evaluated. Three point scale of deficit intensity from + to +++ has been established. Peripheral nerve tumours were mainly benign and malignant neoplasm was only found in 2 cases. There were no new neurological deficits after surgical treatment. The surgical treatment results depended on the histopathological pattern, size and localisation of tumours and the choice of the optimal operative technique.
