Table 3. Complications associated with dural tears.
Complication | Comment |
Duro-cutaneous fistula | The formation of a fistula between the dura and the skin can subsequently result in either arachnoiditis, or epidural abscess, or meningitis. |
Cerebrospinal fluid leak | A continuous leak predisposes to the development of pseudomeningocele formation and possible trapping of nerve roots with associated neurologic symptoms. The symptoms may include sciatica and cranial nerve palsies; for example, strabismus may occur as a result of a cranial nerve VI palsy. |
Headache | A debilitating orthostatic headache often arises. The headache is postural; when the patient sits upright, it occurs, and when the patient is recumbent, it resolves. |
Subcutaneous fluid collection | Proper wound healing may be prevented by fluid collection. This can result in breakdown of the wound, incision site infection, or both. |
