title: Sirolimus-eluting stent fracture and aneurysm formation in a young child with a coronary artery bypass graft.
abstract: Clinical experience with coronary stent implantation in children is very limited. In-stent restenosis, thrombosis, and aneurysm formation are known complications. Recently, fracture of a drug-eluting stent was reported to be a cause of in-stent restenosis, but the natural course of stent fracture and proper management options remain uncertain. This report describes the case of a 7-year-old boy with a sirolimus-eluting stent implanted to treat stenosis of a coronary artery bypass graft who showed complete stent fracture and aneurysm formation. During the 2-year follow-up period, the boy experienced complete regression of the aneurysm without in-stent restenosis.
