Endovascular Shunting for Communicating Hydrocephalus Using a Biologically Inspired Transdural Cerebrospinal Fluid Valved eShunt^® Implant

Key points

A transvenous trans-dural approach to communicating hydrocephalus was developed which mimics the function of the arachnoid granulation by shunting CSF to the jugular vein.
The low profile eShunt implant is delivered using endovascular method percutaneously via the femoral vein and the inferior petrosal sinus into the cerebello-pontine angle cistern.
Unlike conventional surgical ventriculo-peritoneal or -atrial shunts, the eShunt approach avoids hydrostatic pressure gradient-related siphon effect
