RESUMO
Symptomatic spinal epidural hematoma (SSEH) following spinal surgery is rare but one of the serious complications. SSEH can leave devastating neurological consequences if missing the optimal timing for treatment. The early diagnosis of SSEH is critical to the neurologic recovery, and MRI examination can help to check the location and the scope of the hematoma and provide imaging information for surgical operation. The risk factors of SSEH can be divided into preoperative factors, intraoperative factors and postoperative factors. The occurrence of SSEH can be minimized by controlling the risk factors, exact hemostasis and reasonable perioperative management. Patients with mild paralysis can choose conservative treatment, while patients with severe or progressive nerve injury (manual muscle testing <3) and unendurable nerve root pain should choose to clean the hematoma and decompress the nerve as soon as possible.
