Abstract
A retrospective review of the medical records of adults with diagnosed spinal epidural abscess (SEA) admitted to the Departments of Neurosurgery and Infectious Diseases at the University Hospital of Umea, Sweden, during a 10-year-period (1978–1987) is presented. 10 patients were diagnosed as having SEA during the study period. An iatrogenic origin was suspected in 5. Spondylitis was the most common source of infection. Bacteriological aetiology was confirmed in 8 cases and Staphylococcus aureus was the most common aetiological agent. Trauma and degenerative diseases of the spine, were underlying conditions in 6 cases. Laminectomy was performed in 7 cases. 5/6 patients operated within 48 h after onset of neurological symptoms improved. The remaining case with therapy resistant tuberculous spondylitis died. One patient with surgery after 96 h became paretic. 2/3 conservatively treated patients had a successful outcome while the third patient had a permanent paraparesis due to missed diagnosis. Early diagnosis and early laminec-tomy are still the most important prognostic factors. Recommended initial antibiotic therapy is the combination of a cephalosporin with extended spectrum and metronidazole.
