Depends on shunt. There is not really a "piece" in your neck but just tubing traversing it. If you truly have a ventriculoperitoneal shunt, then the tube goes from the head to the abdomen. Sometimes, we place the distal ends of the shunt elsewhere, such as in the right atirum of the heart. We call this a ventirucloatrial shunt. Other times, we place it into the space around the lung, which is ventriculopleural.
