A young adult who had undergone coronary artery bypass grafting and abdominal aortic replacement with prosthetic vessel later after incomplete Kawasaki disease

SummaryA 33-year-old male with a history of undiagnosed fever at the age of 14 years underwent coronary artery bypass grafting (CABG) and abdominal aortic replacement with a prosthetic vessel. Syncope and chest pain on exertion at the age of 19 years led to the diagnosis of complete occlusion of three major coronary branches and emergency CABG was performed. Fourteen years later, a pulsating abdominal mass was an incidental finding during an outpatient clinic visit and an abdominal aortic aneurysm was confirmed by computed tomography. Based on the recorded symptoms and examination findings, the past history of unexplained fever was suspected to be due to incomplete Kawasaki disease. Co-existing systemic arterial lesions should be sought in patients with multi-vessel coronary disease due to Kawasaki disease, although their prevalence is low.
