[Some observations on prognosis in congenital hydrocephalus (second report) -with reference to the physical handicap in survival cases (author's transl)].

The prognosis of surgically treated congenital hydrocephalus has lately proven to give a remarkably increased expectation of life for patient. However, numerous reports hve shown that the prognosis of congenital hydrocephalus have not always shown favourable turns from the viewpoints of physical and mental disability. This problem has been considered many times over the past years. But, an important problem has been left unsolved. The children of social and physical disability are most serious problem, so we attempt to obain a new interpretation about the influence factors upon the prognosis. Present report consists of follow-up studies of long surviving patients who have studied the fatty acid metabolism in the cerebrospinal fluid during postoperatively, the influeence on prognosis of complicated central nervous system malformation and discussed motor and mental disability in survival cases. Since lipids are essential factors in composing the brain tissues, quantitative composition of fatty acid inC.S.F. was determined by the method of gaschromatography using the arachidic acid as an indicator...
