Conversion of a lumboperitoneal shunt to a lumboatrial shunt through femoral catheterization: technical note.

abstract：OBJECTIVE:This study uses proton magnetic resonance spectroscopy to investigate whether or not idiopathic normal pressure hydrocephalus is associated with neuronal dysfunction or ischemia in the brain. We evaluate whether or not proton magnetic resonance spectroscopy is useful for predicting improvement after long-term...
