Kawasaki disease (KD) is an acute, self-limiting, small-vessel vasculitis with an unknown cause that affects children between the ages of 6 months and 5 years. Its important acute complication is coronary artery aneurysm. Myocardial infarction caused by thrombus formation inside the aneurysm or by organic obstructive lesion following the regression of aneurysm is the principal cause of death in KD. However, coronary artery aneurysms and stenosis requiring surgery are rare in KD. We report an our experience about anesthetic management of child undergone off-pump coronary artery bypass grafting surgery because of coronary artery aneurysm associated with KD.
