Ⅰ.はじめに

 迷走神経刺激(vagal nerve stimulation:VNS)療法は,難治性てんかんに対する低侵襲的な緩和治療である.VNS装置埋め込みの手術手技は,頚動脈内膜剝離術の手技に精通している術者であれば,比較的容易なものとされる17,18,40).しかし,迷走神経を取り扱う以上,不適切な手術操作は不整脈や心停止などの重篤な心臓合併症につながる可能性がある4,22,37).また,VNS装置の埋め込みに伴う感染や,装置の断裂・故障などの合併症に注意する必要がある1,2,5,8,13,14,17,23,27,36,37).VNS療法は,欧州では1994年に,米国では1997年に承認され,既に数万人の難治性てんかん患者がこのVNS療法を受けているので17),VNSに伴う手術合併症については多くの報告があるが,これらの合併症の発生率は低いといわれている1,2,5,8,13,14,17,23,27,36,37).一方,本邦における承認は2010年7月で25),3年を経過した現在,本邦でVNS装置の埋め込みを受けた患者はわずか487例にすぎず,手術合併症に関する報告はほとんどない17,18,40).われわれは2011年3月にVNS療法を導入し25),2年半の間で26例の難治性てんかんに対してVNS装置の埋め込み手術を行った.経験した手術合併症を詳細に報告するとともに,その対策について考察する.
