| Abstract | 「要旨」術前に冠動脈造影を施行した胸部大動脈瘤予定手術39例を対象に, 冠動脈病変との関連から周術期心筋虚血発生率を調べた. 上行・弓部再建術例の50%(13/26)に冠動脈の有意狭窄を認め, 8例に冠動脈再建が同時施行された. その結果, 冠動脈疾患の既往がある群(I群)50%(3/6), 無症候性冠動脈病変を有する群(II群)71%(5/7), 狭窄を有しない群(III群)23%(3/13)に心筋虚血が発生し, I群では2例に心筋梗塞, 3例に低心拍出量症候群を合併した. 下行置換13例中冠動脈狭窄を有していたのは1例のみで, 非狭窄群の2例(17%)に周術期心筋虚血を認めた. |

| Abstract | In 39 patients undergoing elective thoracic aortic aneurysm surgery, we assessed the incidence of coronary artery disease from coronary angiography preoperatively, and evaluated the relationship between coexisting coronary artery disease, perioperative myocardial ischemia and cardiac morbidity. Of them, 26 were operated on for aneurysm involving the aortic arch and 13 for descending aortic aneurysm. Fourteen patients (36%) including 13 (50%) in the former group and one (8%) in the latter group, had significant anatomic coronary artery disease. A concurrent coronary artery bypass (CABG) with repair of the aonic arch was performed in 8 of the 13 patients with correctable coronary artery disease. Perioperative myocardial ischemia detected by ECG was seen in 50% (3/6) of the patients with symptomatic CAD, 71% (5/7) of those with asymptomatic CAD, and 23% (3/13) of those with normal coronary arteries. Two patients with symptomatic CAD who underwent rapair of the aortic arch had a postoperative myocardial infarction. Cardiac morbidity was significantly higher in patients with symptomatic CAD than those asymptomatic CAD, even by aid of a concurrent CABG. (Circ Cont 18：51〜55, 1997) |
