This report describes a case of subacute stent thrombosis (SAT) after drug-coated balloon (DCB). A 79-year-old male was investigated for stable angina. An in-stent restenosis (ISR) lesion was detected by coronary angiography. A skin reaction related to the anti-platelet agent thienopyridine was also observed at this time. Therefore, DCB was used to treat the ISR lesion under single anti-platelet therapy (aspirin). However, 3 days after percutaneous coronary intervention, SAT occurred. OCT did not reveal the underlying cause of SAT. Further data are needed to clarify the optimal duration of dual anti-platelet therapy after DCB.
本报告描述了1例药物涂层球囊（DCB）术后亚急性支架血栓形成（SAT）的病例。一名79岁男性因稳定性心绞痛接受检查。冠状动脉造影检测到支架内再狭窄（ISR）病变。此时还观察到与抗血小板药物噻吩吡啶相关的皮肤反应。因此，在单一抗血小板治疗（阿司匹林）下，使用DCB治疗ISR病变。然而，经皮冠状动脉介入治疗后3天发生了SAT。光学相干断层扫描（OCT）未揭示SAT的潜在原因。需要进一步的数据来阐明DCB术后双联抗血小板治疗的最佳持续时间。
