Stent graft implantation for in-stent restenosis of coronary artery stenosis after Kawasaki disease.

Coronary artery stenosis is a major complication of Kawasaki disease (KD). Several interventional methods in treating coronary artery stenosis have been introduced. However, there are few reports on the management of in-stent restenosis after coronary stent implantation in children. Reported is a 10-year-old boy who underwent successful stent graft insertion for treating in-stent restenosis with neoaneurysm formation after stent implantation for severe coronary stenosis after KD. Twenty-eight months follow-up studies showed no significant restenosis and perfusion defect.
