Abstract

 

PURPOSE: Determine the presence of aneurysms, thrombosis and stenosis is very important for the diagnosis of atypical Kawasaki disease (AKD) and in the follow-up in patients with aneurysms. We aimed to demonstrate high-pitch, low-dose dual-source computed tomography angiographic (CTA) findings in pediatric patients with AKD.

 

METHODS: Over a 5-year period, high-pitch, low-dose CT angiography was performed to determine vascular aneurysms or occlusions in 17 patients who had suspected AKD. The patients ranged from 2 months of age to 11.3 years, with a mean age of 3 years. The American Heart Association’s criteria were used to diagnose AKD.

 

RESULTS: We did not detect any vascular problems in 6 of the patients, and they were not included in our study. Arterial aneurysms were present in 11 patients (their ages ranged from 2 months to 11.3 years, with a mean age of 4.2 years, and 7 of the patients were male). In one patient, there was also a thrombus at an arterial aneurysm. Coronary artery aneurysms were detected in 7 patients, and systemic artery aneurysms were detected in 7 patients. Three patients had both systemic and coronary aneurysms.

 

CONCLUSION: Our results suggest that high-pitch, low-dose dual-source CT can detect all types of aneurysms, stenosis and occlusions of vessels in patients with AKD who were not previously diagnosed. This useful, easy, robust and fast technique may be preferred to diagnose AKD.
