Is a pseudomeningocele serious?
Conclusions: Incidental durotomy and repair causing a large compressive pseudomeningocele after spine surgery is a rare and potentially devastating event.
How is pseudomeningocele treated?
A combined treatment protocol involving open revision surgery for extirpation of the pseudomeningocele, repair of dural tears, and implantation of a subarachnoid catheter for drainage is safe and effective to treat giant pseudomeningoceles.
What is acquired pseudomeningocele?
A pseudomeningocele is an abnormal collection of cerebrospinal fluid (CSF) that communicates with the CSF space around the brain or spinal cord.
How long does Pseudomeningocele take to heal?
Spontaneous resolution may occur over a period of 3 months to 3 years. Healing of the dural defect with gradual resorption of the intra-capsular CSF is the possible mechanism for resolution of these pseudomeningoceles.
What is Pseudomeningocele repair?
Whereas the goals of pseudomeningocele repair, which are extirpation of the pseudomeningocele cavity and elimination of extradural dead space, can typically be achieved by primary closure performed using nonabsorbable sutures, giant pseudomeningoceles (> 8 cm) can require more elaborate repair in which fibrin glues.
Is a Pseudomeningocele a CSF leak?
A pseudomeningocele normally has no surrounding membrane, but is contained in the space between the dura mater and surrounding soft tissues. Pseudomeningocele are commonly found alongside a CSF leak, particularly high-flow leaks and those found on the anterior side of the spinal cord.
What is Spinal Pseudomeningocele?
Pseudomeningocele is an extradural cerebrospinal fluid collection arising from a dural defect, that may be congenital, traumatic, or more commonly as a result of postoperative complication. Majority of the postoperative pseudomeningoceles occurring after lumbar spine surgeries are small and resolve spontaneously.
How do you fix a spinal leak?
After conservative treatments have been tried, an epidural blood patch is the most common treatment for spinal CSF leaks. In this procedure, your own blood is injected into the spinal canal. The blood clot that forms creates a seal to stop the leak.
What does pseudomeningocele mean?
Share via… Abnormal collection of cerebrospinal fluid (CSF) that communicates with the CSF space around the brain or spinal cord. Pseudomeningocele is the term used to describe fluid accumulation due to the leakage of cerebrospinal fluid into the surrounding soft tissue.
What is the incidence of epidural abscess with pseudomeningocele after durotomy?
Pseudomeningocele as unintended “incidental” durotomy: 0.7–2% 1) (may appear similar radiographically to a spinal epidural abscess (SEA), but post-op SEA often enhances, is more irregular, and is associated with muscle edema). Pseudomeningocele is a cause of Failed back surgery syndrome
Can pseudomeningocele cause failed back surgery syndrome?
Pseudomeningocele is a cause of Failed back surgery syndrome Pseudomeningocele on myelography or MRI: suggests nerve root avulsion (very proximal); however, 15% of pseudomeningoceles are not associated with avulsion s, and 20% of avulsions do not have pseudomeningoceles 2) 3) .
What is the relationship between sealant use and postoperative pseudomeningocele?
Adjusted for the significance of sealant usage, there is a 6% increase in odds for complication for every year increase in patient’s age. A statistically significant relationship exists between age and sealant use and the risk of developing a postoperative pseudomeningocele. Emphasis and attention must be placed on meticulous closure technique.
