Coronary arterial lesions due to kawasaki disease: selective coronary angiography in five cases with difficult-to-detect localized stenosis
- 32 Downloads
We report five cases of localized stenosis in coronary arterial lesions due to Kawasaki disease which were difficult to demonstrate by routine selective coronary angiography. Of these cases, three had localized stenosis overlapping the aneurysm, one had localized stenosis overlapping another adjacent branch, and the fifth had localized stenosis at the proximal left main trunk of the coronary artery. The reasons for difficulty in demonstrating the stenoses by routine study include: the localized stenosis was often superimposed on the aneurysm and/or the other adjacent branches, and the catheter was pushed into the inlet of the aneurysm on the proximal left main trunk. For a precise demonstration of a localized stenosis by selective coronary angiography, many angiograms from different perspectives should be taken. In addition, when a large aneurysm exists in the left main coronary artery, selective coronary angiography should be taken without pushing the catheter into the inlet of the aneurysm, and each frame of the cine coronary angiogram should be carefully examined. Care should also be taken to compare with the initial view of the projection.
