[Epidural hematoma after removal of an epidural catheter].

Epidural hematoma is a rare but serious neurological complication of epidural anesthesia. We report the case of a 61-year-old man with squamous cell carcinoma of the lung who suffered an epidural hematoma after undergoing right double lobectomy. Before anesthetic induction an epidural catheter was inserted to the D5-D6 space for postoperative analgesia. Surgery was without noteworthy events and the patient was extubated in the operating room; 5,000 IU of low molecular weight heparin was injected subcutaneously every 24 hours and 5 mg of methadone was provided by epidural catheter every 8 hours. After removal of the catheter three days after surgery, lumbar back pain and hypoesthesia, and weakness in both legs appeared. Epidural hematoma was suspected and treatment with 30 mg.kg-1 of methylprednisolone i.v. was started. Nuclear magnetic resonance imaging of the lumbar spine confirmed the presence of a hematoma at D6-D8. Neurologic symptoms improved in the following hours and additional surgery was not required. The patient was released without neurological symptoms 10 days after lung surgery. We discuss the prevalence, etiology and treatment of epidural hematoma related to epidural anesthesia.
