| Abstract | 「要旨」内胸動脈グラフトに対するPTCAの初期および遠隔期成績について検討した. 対象は1989年7月から'97年12月の間に内胸動脈を使用した冠動脈バイパス術312例(男238, 女74)のうち術後の確認造影にて内胸動脈に狭窄病変を認めた17症例, 17病変. 病変部位は内胸動脈グラフト遠位吻合部16病変, 体部1病変だった. 初期成功は, 17病変中15病変で得られ(初期成功率88.2%), 狭窄率は90.2±7.5%から17.3±14.5%に改善した. 不成功2例は完全閉塞病変であった. また, 早期成功15病変中13病変で行った確認造影では13病変中2病変に再狭窄を認めた(病変部狭窄率25.7±39.0%, 再狭窄率15.4%). 内胸動脈に対するPTCAは, 完全閉塞病変でなければ早期成功率は高く, 再狭窄率も低い. |

| Abstract | We evaluated the initial and long-term efficacy of percutaneous coronary angioplasty (PTCA) to the internal thoracic arteries (ITA) which were used as the coronary artery bypass graft (CABG). From July 1989 to December 1997, CABG surgeries using the right and/or left ITA were performed in 312 patients (238 men, 74 women, the mean age 63 ± 8 years old) at our hospital. Post-operative coronary angiography showed any significant stenosis of the ITA in 17 patients (5.45% ;9 men, 8 women). Stenotic sites were observed in 16 lesions at the distal anastomoses of the ITA and in one lesion at the mid portion of the ITA. PTCA was applied to the stenotic lesions of the ITA. Of 17 patients, PTCA succeeded in 15 patients (Mean stenotic ratio was improved from 90.2 ± 75% to 17.3 ± 14.5%). The remaining 2 patients had total occlusion. No complications resulted ; neither death, myocardial infarction, dissection of the coronary artery, or the use of any stent was observed during the PTCA procedure. |
