Abstract

Liquorpheresis (cerebrospinal fluid 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. Continuous or intermittent cerebrospinal fluid (CSF) replacement may be an alternative approach not explored thus far. Here, we review previous experiences in the use of liquorpheresis in autoimmune and degenerative neurological diseases. Then we describe previous technical reports  and provide some new innovations in order to design bidirectional CSF shunting systems that can be complemented either with a deposit of artificial CSF or with a filter of CSF, allowing CSF replacement or liquorpheresis respectively. Both options would lead to mechanical dilution of the patient's CSF.
