Lumbar epidural hematoma following lumbar puncture: the role of high dose LMWH and late surgery. A case report.

Spinal epidural hematoma (SEH) is a known complication of spinal surgery, but the incidence of post-surgical SEHs that result in neurologic deficits is extremely rare (0.1%). Patients that require multilevel lumbar procedures and/or have a preoperative coagulopathy are at a significantly higher risk of developing an epidural hematoma. The introduction of higher dose of low molecular weight heparin (LMWH) twice daily 30 mg regimen) increased the reported incidence of neuroaxial hematomas. Surgery performed within 8 hours makes good or partial recovery of neurologic function. Our patient was also started on higher dose of LMWH and developed neurological deficits due to a SEH following lumbar puncture. She underwent operation after six days and she had a mild recovery following the operation. Current administration of high doses of LMWH can cause SEH even after a lumbar puncture, which was performed without multiple attempts. Although surgery performed within 8 hours makes good or partial recovery of neurologic function, laminectomy and epidural hematoma evacuation performed after three days can also have successful results.
