title: Complications in the surgical treatment of lumbar stenosis.
abstract: The authors analyze the complications which may occur in the surgical treatment of lumbar stenosis. They report 4 cases of cauda equina syndrome and 8 dural tears in 96 patients aged from 21 to 81 years submitted to multiple bilateral laminectomy. Based on a review of the patients some considerations on surgery for the treatment of lumbar stenosis are discussed. The advanced age of the patients, hypertension, diabetes, vasculopathies in general, severe neurological deficit dating back some time contraindicate surgery. When surgery is indicated a correct preoperative evaluation by MRI from T12 to the sacrum is required to determine the extent of the laminectomy and a safe and accurate intra- and postoperative bleeding control is mandatory. Dural laceration may be repaired by a thoracolumbar fascia patch.
