How can Kawasaki disease cause serious complications?
Children with Kawasaki disease can develop inflammation of the arteries of various parts of the body. This inflammation of the arteries is called vasculitis. Arteries that can be affected include the arteries that supply blood to the heart muscle (the coronary arteries). Vasculitis can cause weakening of the blood vessels and lead to areas of vessel widening (aneurysms). Coronary aneurysms have been reported in up to 25% of those with Kawasaki disease. Because of the potential for heart injury and coronary aneurysms, special tests are performed to examine the heart. Children are typically evaluated with an electrocardiogram (EKG) and an ultrasound test of the heart (echocardiogram). Other arteries that can become inflamed include the arteries of the lungs, neck, and abdomen. These effects can lead to breathing problems, headaches, and pain in the belly, respectively. How is Kawasaki disease treated? Kawasaki disease is treated with high doses of aspirin (salicylic acid) to reduce infla
