A clinical study regarding the outcomes of symptomatic spinal epidural haematoma after adult spinal deformity surgery

Abstract Symptomatic spinal epidural haematoma (SSEH) is a rare but serious postoperative complication. This study aimed to assess the prevalence, causes and treatment of SSEH after adult spinal deformity (ASD) surgery. The patients admitted from August 2012 till August 2016 were retrospectively reviewed using case notes. During these four years, 102 patients were admitted with adult spinal deformity, out of which 3 (2.9%) developed post-operative SSEH. The duration between surgery to onset of SSEH was 10-13 hours (average 11.7 hours) post-operatively. Three patients were treated by haematoma evacuation at 8.5-14 hour (average 11.4 hours) after the symptoms appeared. One patient had improved by 2 Frankel grades, and two patients had improved by1 Frankel grade at the last follow-up. The results concluded that post-operative SSEH occurred in 2.9% of ASD patients who underwent corrective spinal procedures. Improvement in neurological deficits can be achieved by early haematoma evacuation. Continuous.....
