가와사끼병에 의해 발생한 거대 관상동맥류의 협착 및 혈전형성을 보인 환아에서 시행한 Graft Stent 삽입술 1례

Abstract

Kawasaki disease is an acute systemic vasculitis of unknown origin. Coronary aneurysm or ectasia is one of the most serious complications of Kawasaki disease. The major complication of Kawasaki coronary disease is myocardial infarction caused by thrombus formation inside the aneurysm or by organic obstructive lesion following the regression of aneurysm. Percutaneous balloon angioplasty, rotational ablation, directional coronary artherectomy, stent insertion and coronary artery bypass graft can be used to treat coronary artery stenosis or occlusion. We describe a 6-year old boy who had an episode of Kawasaki disease with giant coronary artery aneurysm diagnosed at the age of 3 years. Surveillance echocardiogram showed giant coronary aneurysm with stenosis and large mural thrombus in the proximal portion of left main coronary artery. So we inserted two polytetrafluoroethylene(PTFE) covered graft stent without complication.
