Aortocoronary bypass surgery for Kawasaki disease

Summary A case of Kawasaki disease with precordial pain in a 6-year-old boy is described. Coronary arteriography revealed large aneurysms with subtotal obstruction of the left anterior descending artery and long-segment narrowings of the right coronary artery. The left ventriculogram revealed an old myocardial infarction of the inferoposterior wall of the left ventricle. The patient was given aortocoronary bypasses using both a left internal mammary artery and a fresh saphenous vein graft to the left anterior descending artery. Serial angiographic study, performed 6 weeks after the operation, revealed these grafts were both patent. Using the two techniques together may have the potential benefit of the saphenous vein bypass graft functioning as a temporary measure to ensure survival with the hope that the internal mammary artery supply will continue to grow.
