Delayed Onset of Spinal Subdural Hematoma after Vertebroplasty for Compression Fracture: A Case Report

ABSTRACT

Vertebroplasty (VP) is a well-known therapeutic modality used to treat pain associated with vertebral compression fractures. Major complications such as cord or root compression, epidural and subdural hematomas (SDH) and pulmonary emboli, occur in less than 1% of patients who undergo VP after compression fracture. Spinal SDH is an extremely rare complication that usually happens a few hours after the procedure. We report a case of spinal SDH that developed at two weeks after a successful VP. We also reviewed related literatures and discussed its possible pathogenesis.
