Surgical risks of epidural hemorrhage

Epidural hemorrhage is mostly caused by trauma, and is often associated with skull fractures. Therefore, epidural hemorrhage can occur when there is bleeding at the fracture site or when the broken end of the fracture punctures the dural blood vessels or dural sinus. Therefore, the risk of surgery is mainly when the bone flap is lifted during the operation. If the operation is too rough, the dura may be damaged, resulting in massive bleeding, which may cause difficulty in hemostasis when it affects the superior sagittal sinus. Excessive removal of the hematoma during surgery can cause the compressed brain tissue to reset too quickly, resulting in the dissection of the contralateral dura mater, resulting in the formation of the contralateral epidural hematoma or the aggravation of the primary intracranial brain injury, and more surgical treatment is required. Another is the possibility of postoperative infection. Because craniocerebral injury is often combined with skin contusion and skull dura mater injury, postoperative incision infection may occur or even spread to the brain to cause intracranial infection, and the prognosis of patients is poor.
