Hope you and your child are in good health and spirits.I have read your query and yes, you are right approximately 20% of children who suffer from kawasaki disease have chances of developing aneurysms characterized by swelling of a section of blood vessels.Following treatment of aneurysm, it goes away and arteries look normal. However, the wall of aneurysm is basically weak and abnormal once formed. A clot or thrombus nay develop in aneurysm leading to serious heart problems in future. You must consult your child's medical specialist and cardiologist regularly. A heart scan may become necessary if symptoms and signs appear.Hope he will never get any complications. </s>
