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

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.....

Cauda equina syndrome due to Factor Xa inhibitor (Rivaroxaban): Case report and review of literature

Background: Factor Xa inhibitors are widely used by the physicians to reduce the incidence of thrombosis in order to protect the cardiovascular function. Although complications of bleeding and spontaneous gastrointestinal sources have been reported before, there are very sporadic cases of spinal epidural haematoma causing neurological compromise. Case presentation: We report a case of spontaneous spinal epidural haematoma (SSEH) in an 85-year-old female patient treated with Rivaroxaban, a new agent to prevent the incidence of thrombo-embolic events. Anticoagulant therapy is a recognised risk factor in the development of spontaneous bleeding and haematomas. The patient presented to the emergency department with sudden onset of severe back pain in the lumbar spine associated with paraplegia in the lower limbs. Magnetic resonance imaging (MRI) of the spine demonstrated a SSEH from T12 to L5 affecting the cauda equina. Rivaroxaban was discontinued and the patient was monitored as an inpatient. There was gradual improvement in the symptoms of the lower limbs. Conclusion: This rare condition of incomplete cauda equina syndrome due to Rivaroxaban therapy has not been reported previously. Clinicians must have a high index of suspicion in patients on regular anti-coagulation regimen.

Spontaneous spinal epidural haematoma following intra-arterial catheter-directed thrombolysis: A case report

A 79-year-old Chinese gentleman presented with unilateral acute lower limb ischaemia and received intra-arterial catheter-directed thrombolysis, initially with good result and reversal of the ischaemia. However, he developed an extensive spontaneous spinal epidural haematoma within hours of the procedure and was left with permanent paraplegia after being deemed unsuitable for decompressive spinal surgery. This report serves as a reminder of the risk of severe complications of catheter-directed thrombolysis by describing this rare but devastating side-effect that occurred even despite early detection from onset of symptoms.
