Abstract
In our institute, 1100 patients with a history of Kawasaki disease have been catheterized for selective coronary arteriography. Their age at examination ranged from four months to 13 years. Coronary artery lesions (CAL) were found in 262 patients. As far as the type of the CAL was concerned, occlusion was noted in 20 (7.6%), segmental stenosis in 15 (5.7%), localized stenosis in 62 (23.7%), aneurysm in 93 (35.5%), and dilatation in 72 patients (27.5%). In terms of the total number of lesions, there were 23 occlusions, 19 segmental stenoses, 109 localized stenoses, 449 aneurysms and 307 dilatations. The 262 patients with CAL were analyzed according to the interval from the onset to the time of selective coronary arteriography. The incidence of both occlusion and segmental stenosis was lowest in the group who were catheterized shortly after the onset of disease, whereas the prevalence of aneurysm was highest in this group. But the prevalence of dilatation was highest in the group of patients who were catheterized late. A total of 12 patients had to undergo femoral arterial thrombectomy for arterial thrombosis following the catheterization, but no other major complication was experienced.
