Postoperative Brown-Sequard syndrome complicated by spinal epidural haematoma after cervical laminoplasty: A case report and literature review

Symptomatic epidural hematoma after cervical laminoplasty has a reported incidence rate of 0.44%-1.2%. This case study examined a 47-year-old man who presented with dorsal cord compression from cervical vertebrae C3 to C7 and underwent unilateral open-door laminoplasty (left to right side) and a partial laminectomy of C2-C7. At 5 h after surgery, the patient experienced left-side weakness that rapidly developed into hemiparesis, but pain and temperature sensation remained constant on both sides. Computed tomography (CT) revealed a left epidural haematoma compressing the spinal cord from C3 to C6 that resulted in Brown-Sequard syndrome. The hema-toma was evacuated 2 h after the onset of symptoms. The patient recovered successfully after surgical decompression.
