Surgical Treatment of Syringomyelia Associated with Chiari Malformation

I．はじめに

　脊髄空洞症に対しては，種々の外科的治療が行われているが^{1,4,5,8-10,14,15）}，今回われわれは，Chiari奇形に合併した脊髄空洞症の外科的治療につき報告する．本報告では，Chiari奇形に合併した脊髄空洞症に対してsyringosubarachnoid shunt（S-S shuntと略す）が有効な治療法であることを述べるとともに，S-S shuntの問題点についても言及する．

　There is now a controversy about the methods of surgical treatment in syringomyelia associated with Chiari malformation. In this report, the authors emphasize that syringosuharachnoid shunt is effective as a surgical procedure or syringomyelia associated with Chiari malformation.

　From 1982 to 1986, 17 patients with syringomyelia associated with Chiari malformation were surgically treated. Seventeen patients underwent 22 operative procedures for syringomyelia.
