Abstract
A 65-year-old man on dialysis was performed Zotarolimus-eluting stent implantation in right coronary artery a month before and his symptom disappeared after stent implantation. He was readmitted for coronary intervention for a residual coronary lesion in left circumflex artery. Coronary angiography showed a significant stenosis within the Zotarolimus-eluting stent in right coronary artery. Intravascular ultrasound and optical coherence tomography showed a protruding material within the stented segment. We tried to use a thrombus suction catheter and material was successfully removed. Pathological examination demonstrated a block of thrombus formation within the stent.
