Abstract
OBJECTIVES: Spinal cord compression from a hematoma is a rare serious complication of neuroaxial anesthesia. Our objective was to investigate cases reported and published by Spanish authors. MATERIAL AND METHODS: Cases of spinal cord compression related to neuroaxial hematomas (epidural, subarachnoid, or both) reported at congreses and meetings in Spain or published in Medline-indexed journals from 1989 through December 2002 were reviewed. The clinical characteristics, risk factors, treatments, and outcomes were described for each case. RESULTS: Since 1996, when the first cases were reported, 20 cases in all have appeared: 8 related to sub-arachnoid anesthesia, 8 to epidural anesthesia, 1 to a combination, and 1 to diagnostic lumbar puncture. In 2 cases, the neuroaxial technique used was poorly defined. Factors that might have caused the complication could be identified in 11 cases, among which there were 7 cases of anesthetic puncture or manipulation of an epidural catheter during a period of hemorrhagic risk because of antithrombotic therapy. The hematoma was evacuated surgically in 11 cases, and medical treatment was provided in 9 cases. The neurologic outcome was satisfactory in 14 cases. CONCLUSIONS: The number of compressive spinal hematomas reported or published by Spanish authors is fairly high, and there are cases related to both sub-arachnoid and epidural anesthesia. Nonsurgical treatment was provided in 45% of the cases and the outcome was satisfactory in 70%. Risk factors were identified in over half of the reported cases.
