-==Epidural hematoma in the spine==
-Bleeding into the epidural space in the spine may also cause epidural hematoma. These may arise spontaneously (e.g. during [[childbirth]], or as a rare complication of anaesthesia (such as [[epidural]] anaesthesia) or surgery (such as laminectomy).
-The anatomy of the epidural space means that spinal epidural hematoma has a different profile from cranial epidural hematoma. In the spine, the epidural space contains loose fatty tissue, and the '''epidural venous plexus''', a network of large, thin-walled veins. This means that bleeding is likely to be venous. Anatomical abnormalities and [[coagulopathy| bleeding disorder]]s make these lesions more likely.
-They may cause pressure on the spinal cord or [[cauda equina]], which may present as pain, muscle weakness, or bladder and bowel dysfunction.
-The diagnosis may be made on clinical appearance and time course of symptoms. It usually requires [[MRI]] scanning to confirm.
-The treatment is surgical decompression.
-The incidence of epidural hematoma following epidural anaesthesia is extremely difficult to quantify; estimates vary from 1 per 10,000 to 1 per 100,000 epidural anaesthetics. This means that a typical anaesthetist or [[anesthesiologist]] is statistically unlikely to cause one in a whole career.
