Comparative studies were performed on effects, complications and shunt impairments of ventriculo atrial shunt (V-A shunt) and ventriculo-peritoneal shunt (V-P shunt) operations, mainly on the basis of our experiences with 62 V-A shunt and 19 V-P shunt operations. From the standpoint of shunt effect and durability, V-A shunt was definitely superior. From the standpoint of safety, V-P shunt was superior. We consider that, in hydrocephalic cases where both V-A shunt and V-P shunt have good indications, V-A shunt will be the operation of choice. However, in cases where any occult infection of CSF is suspected for, V-P shunt will be the operation cf choice. Various attempts hitherto performed by us for preventing postoperative complications and shunt impairments following V-A shunt, were mentioned. Remote prognosis of our hydrocephalic cases treated with shunt operations, as revealed by enquete method, was also reported.
