A 71 year old male patient who experienced acute myocardial infarction (AMI) 4 years ago and had a history of polycythemia vera and thrombocythemia was admitted because acute attack of chronic heart failure. Coronary angiography revealed an unusual filling defect in the middle segment of the left anterior descending (LAD) coronary artery and IVUS showed it is a HLS which is different from dissection or woven coronary artery. We review the recent literature of HLS in this article and further investigations are warranted for the optimal management of HLS.

左冠状动脉前降支中的蜂窝状结构（HLS）——血管内超声（IVUS）显示真性红细胞增多症和血小板增多症患者的血栓再通

一名71岁男性患者，4年前经历过急性心肌梗死（AMI），有真性红细胞增多症和血小板增多症病史，因慢性心力衰竭急性发作入院。冠状动脉造影显示左前降支 (LAD) 冠状动脉中段存在异常充盈缺损，IVUS 显示这是 HLS，不同于夹层或编织冠状动脉。我们在本文中回顾了 HLS 的最新文献，并需要进一步研究以实现 HLS 的优化管理。
