[Surgery for aortic aneurysms with coronary disease].

Between 1981 and 1988, 52 patients with dissecting aneurysms were operated and four of them (7.7%) had right coronary dissections that were repaired by Bentall's method with or without right coronary bypass grafting (CABG). Three (8.5%) of 35 patients with thoracic aneurysms had coronary disease. Among them, two had one vessel disease (1VD) and one had 2VD; two underwent temporary axillofemoral bypass grafting (AFBG) without CABG and one underwent extracorporeal circulation with CABG. Eight (5.6%) of 142 patients with abdominal aneurysms had coronary disease. They consisted of three patients with 1VD, two with 2VD and three with 3VD; their ejection fraction rates were 0.46 to 0.75. Three of them underwent temporary AFBG and one first underwent CABG but later underwent abdominal aortic graft replacement. In conclusion, patients with good coronary distal run-off and a low ejection fraction rate (under 0.5) should initially undergo CABG, but for those with poor run-off, temporary AFBG is better to prevent cardiac afterload.
