PECULIARITIES OF TREATMENT OF PATIENTS WITH TUMORS OF CERVICAL SPINAL NERVES WITH PARAVERTEBRAL SPREAD

Introduction. We aimed to evaluate the results of surgical treatment of patients with peripheral nerve sheath tumors with specification of the peculiarities of their structure and extension pattern, and to determine prognostically unfavorable morphological features in tumors of peripheral nerves. Materials and methods. The study is based on a retrospective analysis of the medical records of 65 patients who were operated in our Neurosurgical Department during 2008 to 2018. The indication for the operation was worsening of neurological symptoms as a result of the tumor process in the cervical spine, verified by methods of neuroimaging (spondylography, CT, SCT, MRI). The choice of the surgical access depended on such factors as the tumor location regarding to the dura mater and the nervous structures, bones. Discussion: the expected response to surgical treatment in patients with peripheral nerve sheath tumors depends on many factors: localization, directions of neoplasm extension, radical nature of the treatment and the histological variant of the tumor. The tumors of the spinal nerves are quite common and form up to the 48% of all tumors of the spinal localization. The overwhelming majority of such tumors leads to the compression of the spinal cord and its nerve roots, and to considerable neurological symptomatology. Determining the tactics of surgery and the choice of surgical access is an important component for achieving long remission. The choice of an adequate approach makes it possible to totally remove the tumor, reduces the time of intervention, blood loss, injuries to the nervous structures during removal of the tumor.
