From the Research
Treatment of thoracic syrinx primarily involves surgical intervention, with the specific approach depending on the etiology, and the goal of preventing neurological deterioration rather than reversing existing damage. The primary treatment options include posterior fossa decompression with or without duraplasty for Chiari malformation-associated syrinx, and procedures such as laminectomy with syrinx fenestration, syringosubarachnoid shunting, or syringoperitoneal shunting to divert fluid for post-traumatic or tumor-related syrinx 1. Some key points to consider in the treatment of thoracic syrinx include:
- Surgical intervention is the primary treatment, with the specific approach depending on the etiology
- Conservative management is appropriate for asymptomatic patients or those with stable, mild symptoms, involving regular MRI monitoring every 6-12 months to assess progression
- Medication therapy is primarily symptomatic, including gabapentin, pregabalin, or amitriptyline for neuropathic pain
- Physical therapy helps maintain function and prevent complications like muscle atrophy
- The treatment approach should be individualized based on symptom severity, progression rate, and underlying cause Some studies have shown that syringosubarachnoid shunting can be an effective treatment option for syringomyelia, with good results in terms of pain relief and improvement in neurological function 2, 3. However, the decision to use a shunt should be made on a case-by-case basis, taking into account the individual patient's symptoms, progression rate, and underlying cause of the syrinx. It's also important to note that syrinx-related neurological deficits often remain permanent even after successful treatment, so the goal of treatment is to prevent further neurological deterioration rather than to reverse existing damage. In terms of specific treatment options, a study published in 2001 found that posterior craniovertebral decompression and selective placement of a syringosubarachnoid shunt was an effective and safe treatment for patients with Chiari I malformation and syringomyelia 1. Another study published in 2005 found that shunting procedures were effective in some patients with syringomyelia associated with spinal arachnoiditis, but that decompression procedures of the spinal subarachnoid space may be an alternative primary surgical treatment except for patients with longitudinally extensive arachnoiditis 4. Overall, the treatment of thoracic syrinx requires a comprehensive and individualized approach, taking into account the underlying cause, symptom severity, and progression rate, with the goal of preventing neurological deterioration and improving quality of life.
