When an abrupt malfunction occurs, symptoms can develop very rapidly potentially leading to coma and possibly death. The shunt system continuously performs its function of diverting the CSF away from the brain, thereby keeping the intracranial pressure within normal limits. An alternative operation called endoscopic third ventriculostomy may be recommended.
Most cases of shunt malfunctions occur due to occlusion (blockage) of the proximal ventricular catheter. In these instances, pumping of the shunt will show a valve that is slow to refill, or does not refill at all.
