Abstract
The main treatment for syringomyelia associated with Chiari Type 1 malformation is surgery – decompression of posterior cranial fossa, in order to eliminate the cerebrospinal fluid flow block at the craniovertebral transition level. However, successful surgical treatment does not always lead to regression of syringomyelia symptoms. The literature presents controversial data about factors affecting the postoperative outcome. We examined 44 patients, who underwent decompression of the posterior cranial fossa, in order to assess the postoperative dynamics of syringomyelia associated with Chiari Type 1 malformation and to identify predictive factors. Analysis of clinical and neurovisual parameters before surgery and at the distant postoperative stage (2 years or more after treatment) made it possible to determine the frequency of the dynamics of spinal symptoms and symptoms of the large occipital foramen and identify the main factors affecting the postoperative outcome.
