A 57-year-old woman with a history of idiopathic thrombocytopenia presented with chest pain and inferior ST-segment elevation myocardial infarction following percutaneous coronary intervention to a distal right coronary artery stenosis. A right femoral artery angiogram showed an acute stent thrombosis. After blood flow was restored with intracoronary thrombectomy and balloon angioplasty, optical coherence tomography was performed using DragonFly Optis (Abbott Vascular). Unfortunately, it was difficult to advance the catheter beyond the stented segment. On review of the image, there were 2 circular figures resembling "crop circles" extending proximally for several frames.
一位 57 岁女性，既往有特发性血小板减少症病史，在经皮冠状动脉介入治疗远端右冠状动脉狭窄后出现胸痛和下壁 ST 段抬高型心肌梗死。右股动脉造影显示急性支架内血栓形成。经冠状动脉血栓切除术和球囊血管成形术后恢复血流后，使用 DragonFly Optis（雅培血管）进行光学相干断层扫描。不幸的是，导管很难推进到支架段以外的部位。在查看图像时，有 2 个圆形物体，类似于“麦田怪圈”，在几个帧上向近端延伸。
