Hématome péridural rachidien spontané au cours de la grossesse

Spontaneous spinal epidural haematomas are quite rare. We report here the case of a 27-year-old woman, without previous history of relevant medical disorder, who presented with acute paraplegia at 36 weeks of gestation. MRI performed in emergency revealed a T8 epidural haematoma. The management consisted in an emergency Caesarean section under general anaesthesia, followed immediately by a T8 laminectomy allowing the spinal cord decompression 14 hours after the first symptoms. Neurologic recovery was rapid and complete, except for bladder dysfunction persisting one month later. Spontaneous spinal epidural haematomas require a prompt diagnosis because neurologic prognosis essentially depends on the interval of time between onset of symptoms and surgical decompression. Obstetrical management especially depends on the term of pregnancy. For the anaesthesiologist, the difficulty is the management of both pregnant condition (full stomach general anaesthesia) and spinal cord compression (maintenance of spinal cord perfusion pression and limitation of ischaemia and oedema).
