Acute spinal cord compression due to spinal subdural hematoma after spinal anaesthesia in-patient under anticoagulant drug

Background Subdural spinal cord hematomas are very rare condition. They most often occur in patients with primary or secondary blood haemostasis disorders and following lumbar punctures. Early diagnosis and management preserve functional prognosis. Case description We report the case of a female 69-year-old patient on oral anticoagulant, Acenocoumarol 4 mg (SINTROM) for previous aortic prosthesis. The patient had undergone surgery for appendicitis under spinal anaesthesia 2 days before her admission in neurosurgery department. She was admitted in emergency for 1/5 central flaccid paraplegia with sensitive umbilical level. A spinal MRI performed showed a collection intradural in intermediate signal in T1 and hyposignal in T2 with echo gradient of 8 mm thickness extended from D8 to L2 compressing the marrow with anomalies of intramedullary signal extended from D8 to the conus medullaris. We retained indication to operate the patient early in emergency because of acute spinal cord compression. We performed T12-L2 laminectomy, durotomy and evacuated hematoma. Postoperative marked by an immediate recovery of sensitivity and an onset of motor recovery from 1/5 to 2/5 and 4/5 follow up at on year with physiotherapy. Conclusion Spinal cord compression due to subdural spinal hematomas not often described especially in patients with haemostasis blood disorders due to anticoagulants drugs. In addition, we should pay attention with lumbar puncture in these patients. Emergency surgery allows a good prognosis about recovery of neurological disorders.
