Giant Aortic Aneurysm Complication of Kawasaki Disease

Abstract

This study presents a case of a giant aneurysm of the ascending aorta that evolved to rupture in a pediatric patient. The diagnosis was made possible through echocardiogram, which was subsequently confirmed by an aortic computed tomography (CT) angiography. The patient was referred for surgical intervention and demonstrated favorable outcomes. The authors describe the differential aspects of the clinical manifestations and immune response in Kawasaki disease. While the coronary arteries represent the main site of aneurysm formation in KD, they are not the sole location, and it is important to keep in mind that aortic aneurysms may occur. Despite the rarity of aortic aneurysms in KD, a take-home message to be learned from this case study is to consider KD in the context of acute onset ascending aortic aneurysm.
