SummaryTransvenous mitral commissurotomy (TMC) was conducted with transesophageal echocardiography (TEE) in two patients with mitral stenosis. It was possible to see clearly not only the intracardiac structures to be examined by TMC, such as the right and left atria, interatrial septum, and mitral valve, but also the instruments used in TMC, such as the catheter, guidewire, and balloon. It was possible to determine the positional relation between the intracardiac structures and instruments. We could observe all procedures other than Brockenbroughs procedure by both TEE and fluoroscopy at the same time. Although safety and reliability cannot be confirmed from just the two present cases, TEE appears to be applicable to TMC.

冠動脈バイパス手術(CABG)における動脈グラフトとしての右胃大網動脈(RGEA)は,構造上血管平滑筋が多い筋性血管であり,内胸動脈と比較し動脈硬化が起こりやすく,また発達の個人差が大きいとされている.したがって術前にグラフト材料としての適否を検討することが望ましく,その検査法としてはカテーテル血管造影検査が一般的である.最近われわれは,カテーテル血管造影検査の代わりに,CT-angiographyによりRGEAを評価している.同検査法は,より低侵襲かつ簡潔に行えるだけでなく,詳細で鮮明なangio画像が得られ,グラフトの適否を決定するうえできわめて有効な検査法であると考えられた.

To improve the outcomes of coronary revascularization with free arterial grafts, we have devised a composite method that uses free arterial grafts with an arterial wall patch. After an arterial graft is anastomosed to the left external iliac artery (EIA), the EIA wall is excised (like a collar) and anastomosed to the aorta. The defect on the EIA is repaired with a vascular graft patch. Our domino patch method is simple, and it causes minimal wall thickness mismatch and allows the use of various arterial grafts anastomosed to any coronary artery. The procedures and early results are reported.

最近5年6か月の間に経験した遠位弓部大動脈瘤は17例であった. 内訳は真性瘤13例, III型解離性動脈瘤でエントリー部が嚢状となったもの4例であった. 17例中3例が破裂瘤であった. 手術補助手段として用いたのは遠心ポンプによる左心バイパス法 (LHB) 6例, 逆行性脳灌流法 (RCP) 5例, 選択的脳灌流法 (SCP) 6例であった. LHBは左鎖骨下動脈を含みそれより遠位側大動脈に瘤が存在する症例に, 左総頸動脈との間で大動脈を遮断して用いた. 手術死亡例はなかったが, 脳梗塞2例を認め, うち1例が入院死した. RCPは限局型の嚢状瘤や破裂緊急例に用いた. 最近の3例にはPCPS回路を用いて, 循環停止を併用して左開胸のみで, 無遮断下に手術を行った. SCPは弓部にまで病変の及んだ症例に用いて, 6例中 (弓部全置換4例) 1例を失った. 瘤の形態, 広がり, 緊急性により補助手段を使い分けた.
