Cerebrospinal fluid (CSF) leakage is a rare complication that can occur due to dural defects during spinal surgery, hindering the improvement of the surgical site and increasing the possibility of infection. DuraSeal® is a dural sealing adhesive that prevents CSF leakage and is used as an adjunct to enable the watertight repair of dural defects when the dura is damaged during spinal surgery. In the present case, DuraSeal® was applied to repair a dural defect in the surgical area after thoracic spine surgery, and no neurological problems occurred immediately after surgery. However, a day later, the patient’s paraparesis worsened; therefore, reoperation was performed and the symptoms improved.
