Detection of a coronary arterial thrombus by indium-111-oxine-labeled platelet scintigraphy

Coronary arteriography revealed significant left anterior descending corona ry artery stenosis in a 72-year-old man with a history of myocardial infarc tion. Stenting of the stenotic vessel was performed. Twelve hours after ste nting the patient complained of chest pain but emergent coronary arteriogra phy did not show sign of any coronary arterial stenosis. Under suspicion of coronary thrombus formation, indium-111-oxine-labeled platelet scintigraph y was performed 5 days after stenting, and revealed accumulation of indium- 111-oxine in the area corresponding to the stent implantation site.
