Transvenous embolisation for spontaneous intracranial hypotension caused by a cerebrospinal fluid–venous fistula
Closed for comments This consultation ended on at Request commenting lead permission
Description
A cerebrospinal fluid (CSF)–venous fistula is an abnormal connection that develops between the space surrounding the spinal cord and nearby veins. The fistula allows CSF to leak into the veins. The loss of CSF can cause pressure in the brain to drop (spontaneous intracranial hypotension).
In this procedure, a small tube (catheter) is inserted through the femoral vein (transvenous) at the top of the leg and guided to the fistula. A liquid is then injected to seal the fistula (embolisation). The aim is to prevent further CSF leaks.
