Repair of giant postlaminectomy pseudomeningocele with fast-resorbing polymer mesh: technical report of 2 cases

Restricted access

Pseudomeningocele is a rare but well-known complication of lumbar spine surgery, which arises in 0.068%–0.1% of individuals in large series of patients undergoing laminectomy and in up to 2% of patients with postlaminectomy symptoms. In symptomatic pseudomeningoceles, surgical reexploration and repair of the dural defect are typically necessary. 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, dural substitute, myofascial flaps, or all of the above are used. The authors present 2 cases of postsurgical symptomatic giant pseudomeningoceles that were repaired using a fast-resorbing polymer mesh–supported reconstruction technique, which is described here for the first time.

ABBREVIATIONS FRP = fast-resorbing polymer.
