Postoperative Cervical Cord Compression Induced by Hydrogel Dural Sealant (DuraSeal®).

Cerebrospinal fluid (CSF) leakage is a potential complication of cranial and spinal surgery. Postoperative CSF leakage can induce delayed healing, wound infection and meningitis. DuraSeal® (Covidien, Waltham, MA, USA) is a synthetic product which has been increasingly used to facilitate watertight repair of dural defects after cranial and spinal surgery. Despite some advantages of Duraseal®, the authors report a patient who developed cord compression following the use of DuraSeal® in cervical spine surgery in which the expansion of the DuraSeal® was believed to be the causative factor.
