Introduction: In treating posttraumatic syringomyelia, subarachnoid-subarachnoid bypass (S-S bypass) surgery has been reported as not only a safe and effective surgical technique but also a safer physiological method owing to the reconstruction of cerebrospinal fluid flow. S-S bypass surgery is also performed for spinal arachnoid lesions with syringomyelia. This study aimed to investigate the results of S-S bypass surgery for spinal arachnoid lesions with syringomyelia and discuss its indications.
Methods: Forty-five patients (posttraumatic syringomyelia in 28 patients, arachnoid web in 6, and other spinal adhesive arachnoiditis in 11) who had progressive neurological symptoms and underwent S-S bypass surgery were included in this study. Clinical symptoms were assessed in terms of improvement, stabilization, or deterioration. The size of the cavity was assessed using preoperative and postoperative magnetic resonance imaging.
Results: Cavity reduction was observed in 36 of 45 patients (82%). Clinical symptoms improved in 32 patients (71%), Seven patients (16%) remained stable, whereas 6 deteriorated (13%).
Conclusions: S-S bypass surgery was effective in reducing the size of the cavity in most cases of spinal arachnoid lesions with syringomyelia.
