[A case report of redo A-C bypass for MCLS performed 13 years after initial surgery].

This is the first report of re-aortocoronary bypass for Kawasaki's disease. The patient is a 22-year old female. She was afflicted with Kawasaki's disease at the age of 6 and had the symptom of angina pectoris at the age of 9. She went through the first aortocoronary bypass, to the left anterior descending artery (LAD) and the right coronary artery (RCA) with saphenous vein graft (SVG). After the first operation, the graft to LAD occluded totally, but she remained asymptomatic and well for 11 years. She had a sudden recurrence of anginal attack at the age of 20. The examinations confirmed ischemia of the anterior wall (LAD area) and the lateral wall (LCX area). Coronary angiography revealed patent SVG with a moderate sign of sclerotic change. We decided on re-aortocoronary bypass, left mammary artery to LAD and gastroepiploic artery to LCX, when she was 22-years old. LIMA was anastomosed to LAD, but LCX was not revascularized, because LCX was not identified and exposed in the operation. In spite of incomplete revascularization, postoperative stress ECG test was negative. Tl-myocardial scintigram confirmed no ischemia of the anterior wall and greatly reduced ischemia in the lateral wall. She became asymptomatic and returned to normal life.
