Coronary aneurysms usually require medication, intervention or surgery to cure and cannot heal on their own. Coronary aneurysms caused by Kawasaki disease need to be treated according to the severity of the Coronary artery aneurysm, determines the treatment, and the prognosis varies according to individual differences and the course of treatment. It is a localized or diffuse dilatation of the coronary arteries that reaches more than twice its original diameter, forming a single or multiple aneurysmal changes. Since it is a bulge in the coronary arteries, the risk is high, so it needs to be treated as soon as it is detected, and Kawasaki’s disease is one of the causes of the disease. Treatment can generally be categorized into three types: medical drug therapy, interventional therapy, and surgical intervention. Drug therapy is mainly used to prevent thrombosis with antithrombotic drugs such as warfarin and heparin, to delay and reverse cardiac changes with angiotensin-converting enzyme inhibitors such as captopril, and to avoid atherosclerosis with statin drugs such as atorvastatin. Interventional therapy can be used to address coronary artery problems by placing stents to restore normal blood flow, and surgery can be used to restore the original blood vessels in patients who cannot undergo interventional therapy or who also have serious complications. If left untreated, serious complications such as angina pectoris and myocardial infarction may occur, which may affect the patient’s daily life and life expectancy, so it is important to treat the disease as soon as it is detected.
