Surgical experience with coronary arterial sequelae of Kawasaki disease in children.

The coronary arterial sequelae due to Kawasaki disease have been treated surgically in five children ranged from 6 to 9 years old. The procedures were aortocoronary bypass surgery in all cases, coronary artery aneurysmectomy in one case and left ventricular aneurysmectomy in one case. The early results of operated cases have been good with the graft patency of 86% confirmed by angiography one month after surgery. The characteristic features of coronary artery damage in patients with Kawasaki disease are coronary artery aneurysms, which manifest wall irregularity, thrombus, calcification and stenosis. The significant stenosis of coronary artery could often be observed at the inlet or outlet of the aneurysm in major coronary artery branches. Although the early results of aortocoronary bypass surgery in the children with Kawasaki disease have been good, long-term follow up is mandatory to investigate the status of autogenous saphenous vein grafted in children.
