Abstract

Liquorpheresis (CSF filtration) comprises a therapeutical approach that has been
proposed to treat several neurological conditions where antibodies, inflammatory
mediators or abnormal peptides are the cause or play an important role in the
pathogenesis of the disease. CSF replacement may be an alternative approach not
explored so far.
Here, we review previous experiences in the use of liquorpheresis in autoimmune and
degenerative neurological diseases. Then we describe previous developments and
provide some new technical innovations in order to design bidirectional CSF shunting
systems. These systems can be complemented either with a deposit of artificial CSF or
with a CSF filter, allowing CSF replacement or liquorpheresis respectively. Both options
would lead to mechanical dilution of the patient’s CSF.
