ABSTRACT
Objective To assess the value and feasibility of 64-slice spiral CT in diagnosis of coronary artery aneurysm in the follow-up of young children with previous Kawasaki disease. Methods Twelve boys (mean age 5.1 years) for follow-up (ranged 1.1 to 5.1 years) with known Kawasaki disease and coronary artery aneurysms underwent coronary CT angiography using 64-slice spiral CT.The number,location,shape and size of each coronary artery aneurysm were recorded and compared with those of echocardiography performed simutaneously. Results A total of 30 coronary artery aneurysms were identified with mean diameter of(7.5±3.8) mm,and mean maximum length of (12.4±9.1) mm.10 aneurysms were small in size,7 aneurysms were medium in size and 13 were giant aneurysms.Fourteen aneurysms were saccular,and the remaining 16 were fusiform. Among the aneurysms in left coronary artery,7 of them were located in the main branch,9 were located in the proximal segment of the anterior descending branch,4 were located at the middle segment of the anterior descending branch,and 2 were located in the circumflex branch.Among the aneurysms in right coronary artery,6 of them were located in the proximal segment,9 were located in the middle segment,and 4 were located at the distal segment.Nine of the aneurysms involved 2 segments of the coronary arteries,and one involved 3 segments.Six stenotic segments were found. Calcification was found in 5 aneurysms and 3 of them had thrombosis. Echocardiography failed to detect 8 aneurysms of small size and located in the middle or distal segments of the coronary arterys.Conclusion The 64-slice CT angiography proved valuable for monitoring young children with Kawasakidisease.
