What is a complication of Kawasaki disease that requires follow-up?

Kawasaki disease is primarily known for its potential to cause significant cardiovascular complications, particularly affecting the coronary arteries. One of the most serious long-term complications associated with Kawasaki disease is the development of coronary artery aneurysms. This occurs due to the inflammation of the blood vessels during the acute phase of the disease, which can weaken the artery walls and lead to abnormal dilations.

Regular follow-up is essential to monitor for these aneurysms, as they can lead to serious outcomes such as myocardial infarction or sudden cardiac death later in life if they are not managed appropriately. Thus, awareness of and monitoring for coronary artery aneurysm formation is a critical component in the long-term management of children who have had Kawasaki disease, ensuring that any necessary interventions or treatments can be undertaken promptly.

In contrast, other options listed, such as intestinal obstruction or neurological impairment, are not commonly recognized complications directly stemming from Kawasaki disease. While a skin rash does manifest during the illness, it typically resolves with treatment and does not necessitate long-term follow-up. Therefore, the coronary artery aneurysm stands out as a significant and ongoing concern for those recovering from Kawasaki disease.
