Syringomyelia can come back, however, requiring additional surgeries which may be less effective.In some cases, including both communicating and non-communicating forms of the condition, a syrinx may require ongoing drainage. This is done with a shunt, which uses tubes and valves to let cerebrospinal fluid (CSF) drain from the syrinx into another cavity within the body (usually the abdomen). This type of shunt, called a ventriculoperitoneal shunt, is particularly useful in cases involving hydrocephalus. By continually draining the syrinx, a shunt can arrest the progression of symptoms and relieve pain, headache, and tightness.Many factors affect the decision to use a shunt. There are risks of injury to the spinal cord, infection, drainage becoming blocked, and bleeding, and they do not always achieve the intended results. Draining the fluid more quickly does not produce better outcomes, but for some syrinxes, a shunt is the only drainage option.In the case of trauma-related syringomyelia, the surgeon operates at the level of the initial injury. The syrinx collapses at surgery, but a tube or shunt is usually necessary to prevent it from returning. Non-surgical interventions
Surgery is not always recommended for syringomyelia patients. While there is no medication which can cure the condition, for many patients, the main treatment is analgesia to manage the symptoms. Physicians specializing in pain management can develop a medication and treatment plan to ameliorate pain. Medications to combat any neuropathic pain symptoms such as shooting and stabbing pains (e.g. gabapentin or pregabalin) would be first-line choices.
A typical cause of PTS would be a car accident or similar trauma involving a whiplash injury.What can make PTS difficult to diagnose is the fact that symptoms can often first appear long after the actual cause of the syrinx occurred (e.g., a car accident occurring and then the patient first experiencing PTS symptoms such as pain, loss of sensation, and reduced ability on the skin to feel varying degrees of hot and cold a number of months after the car accident). Pathogenesis
The pathogenesis of syringomyelia is debated. The cerebrospinal fluid also serves to cushion the brain. Excess cerebrospinal fluid in the central canal of the spinal cord is called hydromyelia. This term refers to increased cerebrospinal fluid that is contained within the ependyma of the central canal. When fluid dissects into the surrounding white matter forming a cystic cavity or syrinx, the term syringomyelia is applied. As these conditions coexist in the majority of cases, the term syringohydromyelia is applied. The terms are used interchangeably.It has been observed that obstruction of the cerebrospinal fluid spaces in the subarachnoid space can result in syrinx formation, and alleviation of the obstruction may improve symptoms. A number of pathological conditions can cause an obstruction of the normal cerebrospinal fluid spaces. These include Chiari malformation, spinal arachnoiditis, scoliosis, spinal vertebrae misalignment, spinal tumors, spina bifida, and others. The reasons that blockage of the cerebrospinal fluid space within the subarachnoid space can result in syrinx formation are not fully understood although a small posterior fossa is one known cause.
