Outcomes of Syringosubarachnoid Shunting in Patients with Syringomyelia Following Foramen Magnum Decompression

Abstract

Introduction:  Syringomyelia following foramen magnum decompression can develop as a progressive neurological deficit that requires effective intervention. Syringosubarachnoid shunting has been brought to attention as a direct method to relieve syrinx pressure and relieve symptoms. The purpose of this study is to assess clinical and radiological outcomes of syringosubarachnoid shunting in such patients.

Material & Methods:  A retrospective study was done of 21 patients of syringomyelia treated by syringosubarachnoid shunting at Hayatabad Medical Complex, Peshawar. The modified Japanese Orthopedic Association score (mJOA) was used to assess clinical recovery, and radiological outcomes included syrinx area change and span. Paired t tests and correlation analysis were performed using statistical analysis with p < 0.05.

Conclusion:  Syringosubarachnoid shunting provides a safe and effective surgical option for the relief of syringomyelia after foramen magnum decompression with significant clinical and syringomyelia improvement and low complication rates. Nevertheless, it is still a good intervention when decompression alone is not enough.
