Abstract 要  旨:遠位弓部大動脈瘤において遠位側吻合部が深い場合,および急性解離(AAD)に対する全弓部置換手術(TAR)の際には,elephant trunk(ET)を用いてきた.今回,その手術成績と対麻痺の発生,およびET周囲の血栓化からその有用性を検討した.【方法】2004~2012年に行ったTAR 122例のうち,ETを併用した40例.原因疾患は遠位弓部大動脈瘤27例,AAD 13例.2007年以降遠位弓部大動脈瘤全例(n=15)で術前CTにてAdamkiewicz動脈(AKA)を同定.【結果】全体の手術死亡1例(2.5%).ET長は平均11.4(7-22)cm.ET長と対麻痺の関連を検討したところ,15 cm以上の15例中4例(27%)に対麻痺を認め,12 cm以下の25例では対麻痺はなかった(p<0.01).AKAを同定温存した14例で対麻痺はなかった.遠位弓部大動脈瘤でET周囲の血栓化により一期的根治を期待した21例中16例(76.2%)で瘤は血栓化し縮小.AADではET長は7-10 cmで対麻痺はなく,13例中2例で完全に解離腔が消失,8例で平均T8まで血栓化.【結論】TAR+ETの手術成績は良好であった.遠位弓部大動脈瘤ではETにより瘤の血栓化が得られるが,その長さが15 cm以上で対麻痺の危険が高く,ET長の決定には充分な注意が必要である.よって,現在ではETによる瘤の血栓化を期待するのではなく計画的二期手術(hybrid手術)を基本方針としている.またAADではET長が7-10 cmで良好な血栓化が得られ,対麻痺もなかったことから妥当な長さであると考える.
