The need for lifelong review of Kawasaki disease in young children depends on the severity of the patient’s lesions. Kawasaki disease is a self-limiting disease. If the patient’s lesion does not involve the coronary artery system, the patient will be reviewed once at 1 month, 3 months, 6 months, 1 year, and 2 years after his or her discharge from the hospital, and after no abnormality is seen on review, the patient can be considered cured without further review. If the patient is complicated by coronary artery aneurysm, close long-term review and follow-up is required until the coronary artery aneurysm disappears. Some patients with thrombosis may require anticoagulation therapy, and such patients may need lifelong review to monitor coagulation index and cardiac function.
