**6. Conclusion**

In patients with a history of KD, the pathogenesis of vascular complications and long-term prognosis are being elucidated by many studies. This suggests an increased risk of atherosclerosis in these populations. However, there are few reports of an increased incidence of atherosclerotic lesions in adult KD patients. Further studies are needed, and careful management of long-term vascular health is required by evaluating vascular function using these clinical tools.
