Postoperative Spinal Epidural Hematoma

The catastrophic morbidity of a symptomatic postoperative epidural hematoma remains a substantial disincentive to start chemoprophylaxis after spinal surgery. The rarity of this complication makes study of its risk factors difficult. Although many surgeons perceive the risk to be higher, the reported incidences of clinically relevant postoperative epidural hematoma are lower, ranging from 0% to 1%. Despite this finding, there is insufficient published data available to precisely define the safety of postoperative chemoprophylaxis. Though not pertaining to prophylaxis, the available evidence does suggest that use of therapeutic doses of heparin in postoperative spinal patients who sustain a PE may have a higher incidence of bleeding complications.
