[A Case of Epidural Hematoma Associated with Epidural Anesthesia]

We report a case of epidural hematoma in an elderly patient with normal coagulability and without difficulty in epidural catheterization. A 76-year-old man with a history of cervical myelopathy was scheduled for gastrojejunostomy under combined epidural and general anesthesia. He had normal bleeding time, coagulation test results, and platelet count. He underwent an epidural catheterization without difficulty. On the first postoperative day, he noticed that could not move his legs with analgesia. After stopping continuous epidural perfusion, he could move legs slightly, but paraplegia remained. On the second postoperative day, MRI of the spine demonstrated a hematoma-like lesion, and severe thoracic and lumbar spinal canal stenosis. Severe vertebral deformation, especially in cases of the elderly, is a potential risk for epidural hematoma after epidural catheterization, because a small hematoma may compress the spinal cord. A careful preoperative evaluation whether to perform epidural catheterization and postoperative observation are required for elderly patients with severe vertebral deformation.
