Ⅰ.はじめに
非腫瘍性Aqueductal stenosisの神経放射線学的診断について,気脳,および脳室造影による所見はよく研究され,数多くの報告がある17,20,23,26,29).しかし,脳血管造影による本病変について検討したものは極めて少ない.
一方,15歳以下の小児においては、検査による侵襲の上からも,脳血管造影が,頭蓋内占拠病巣の診断のために,気脳および脳室造影よりも先に行なわれることの多い現在,本病変を脳血管造影上で的確に把握することは診断上,非常に重要であり,今回,私共が経験した小児例4症例の脳血管造影所見について検討した.
Angiograpic diagnosis of non-neoplastic aqueductal stenosis in 4 children were described. The materials were selected from 160 vertebral angiograms of children below 15 years, performed at the Kyushu University Hospital from July 1967 to March 1974. There were 4 cases of angiographically demonstrated non-neoplastic aqueductal stenosis. These cases were confirmed by pneumoencephalogram and/or pneumoventriculograms, which were performed before and after the Tolkildsen procedure. Ages of the patients varied from 6 to 15 years with average of 11.8 years.
