Final answer:
Coronary aneurysms in Kawasaki disease are typically seen within two to four weeks after the onset of fever. Early treatment with IVIG can reduce the risk of aneurysms, which are caused by the disease's inflammatory process rather than atherosclerosis-related risk factors.
Step-by-step explanation:
Coronary aneurysms in Kawasaki disease typically become visible in the acute phase of the illness, usually within two to four weeks after the onset of fever.
Kawasaki disease is a pediatric illness that involves inflammation of the blood vessels throughout the body, including the coronary arteries.
The risk of developing coronary aneurysms is one of the serious complications of Kawasaki disease, and early treatment with intravenous immunoglobulin (IVIG) can reduce this risk.
Unlike atherosclerotic coronary arteries that develop due to underlying atherosclerosis and risk factors such as smoking, hypertension, and hyperlipidemia, coronary aneurysms in Kawasaki disease are related to the inflammatory process of the disease itself.
It's crucial to monitor children with Kawasaki disease for the development of coronary aneurysms through echocardiography or coronary angiography in order to prevent long-term cardiac complications.
