新生児脳室内出血—その成因と外科的治療について

The Mechanism of the Intraventricular Hemorrhage in the Newborn Infants, and Its Treatment

Ⅰ．はじめに

　新生児脳室内出血は，新生児頭蓋内出血の20-40％を占めるといわれ^5，16），今世紀初頭より注目されており^{2，10，11，15）}，文献の数も多い．これ等文献を通覧すると，本症は，未熟児に特有の疾患とされており，成熟児には少いとされている^{5，6，7，14，16）}．

　われわれは最近1年間に，新生児脳室内出血の5例を経験しているが，全例成熟児であり，未熟児に特有であるという考え方には疑問を感じている．

In the newborn infants, the intraventricular hemorrhage which occurs almost exclusively in premature infants accounts for 20-40% of intracranial hemorrhage and is responsible for 8-15% of their motality.

The diagnosis of intraventricular hemorrhage is difficult to be established by ventricular tap and ventriculography alone.

In the past one year, we have experienced five cases of the intraventricular hemorrhage, all of which were in mature infants in contrast to the general concept. Three cases were successfully treated with ventricular irrigation followed by ventriculo-peritoneal shunt.
