Abstract:Objective: To explore the diagnostic value of echocardiography on Kawasaki disease with coronary artery lesions and compare with multislice spiral CT. Materials and Methods: The date of three hundred and ninty-four patients with Kawasaki disease were analyzed retrospectively. They were examined with echocardiography, in which 53 patients were examined with multislice spiral CT and their results were compared. Results: In the patients with coronary artery lesions, the left coronary artery were more frequently involved than the right coronary artery. In the patients with coronary artery aneurysm, most of the aneurysms were multiple and left main coronary artery and left anterior descending artery were frequently involved. Both techniques coincided with the detection of coronary artery lesions. Conclusion: Echocardiography can make fast and accurate diagnosis on coronary artery lesions with Kawasaki disease, but less sensitive than multislice spiral CT on the distal lesions and stenosis. Both techniques should be combined to improve diagnosis.
