A retrograde ventriculosinus (RVS) shunt is a watertight connection that de
livers excess cerebrospinal fluid (CSF) to the superior sagittal sinus (SSS
) against the direction of blood flow. This method of CSF shunting utilizes
the impact pressure (IP) of the bloodstream in the SSS to maintain the int
raventricular pressure (IVP) more than the sinus pressure (SP) regardless o
f changes in posture or intrathoracic pressure (ITP) and discourages stagna
tion and clotting of blood at the venous end of the connection. It also uti
lizes collapse of the internal jugular vein (IJV) in the erect posture to p
revent siphonage. During the past 8 years, 50 RVS shunts were successfully
implanted using valveless shunting catheters. There were no problems relate
d to incorrect CSF drainage or sinus thrombosis. The results indicated arre
st of the hydrocephalic process, normalization of the IVP and proper shunt
function.
