[Cardiac and extracardiac complications in Kawasaki disease]

Area of Science:

• Pediatric rheumatology
• Vascular pathology
• Infectious disease complications

Context:

• Kawasaki disease commonly leads to coronary artery aneurysms and stenosis.
• Autopsy studies reveal broader arterial involvement in Kawasaki disease.
• Medium and small muscular arteries in multiple organs can be affected.

Purpose:

• To highlight the diverse and often overlooked complications of Kawasaki disease.
• To emphasize the diagnostic challenges posed by rare, systemic manifestations.
• To underscore the importance of recognizing uncommon presentations for timely intervention.

Summary:

• Kawasaki disease can cause injury to medium and small muscular arteries in various organs, not just the heart.
• Incomplete Kawasaki disease with rare neurological or digestive complications can delay diagnosis and treatment.
• Delayed treatment increases the risk of coronary artery aneurysms and hinders recovery from other complications.

Impact:

• Enhances understanding of Kawasaki disease's systemic impact.
• Improves diagnostic accuracy for atypical cases.
• Promotes timely and comprehensive patient management.
• Reduces the incidence of severe cardiovascular sequelae.
