====== External Lumbar Cerebrospinal Fluid Drainage Indications ======

1. to reduce CSF pressure on a site of Cerebrospinal fluid fistula/fistula. Example situations:

a) dural breach during spine surgery or craniotomy (especially posterior fossa)

b) for spontaneous CSF fistula (rare) 

2. to reduce intracranial pressure in cases of communicating hydrocephalus: e.g. drain test for NPH,
or when an infected shunt has been removed

3. to reduce CSF pressure to attempt to increase perfusion of the spinal cord: e.g. during surgery for
abdominal [[aortic aneurysm]], or following [[spinal cord injury]]
