背景：冠状动脉中的蜂窝状结构很少通过冠状动脉内超声或光学相干断层扫描来诊断。此外，其结构机制和对介入治疗的反应仍不清楚。 病例介绍：一名59岁的日本男性因急性失代偿性心力衰竭伴快速心房颤动被转诊至我院。接受抗凝治疗后，冠状动脉造影显示呈辫子状外观，冠状动脉内超声图像证实左冠状动脉前降支中部存在蜂窝状结构。我们将两根导丝插入不同的分区。虽然带有刻划装置的球囊血管成形术无法完全开窗，但植入支架能够轻松地完全压缩该结构。结论：该患者左冠状动脉前降支的蜂窝状结构怀疑是由于心源性栓塞的再通所致。该结构可能由相对较硬的组织组成，但很容易被支架植入压缩。
BACKGROUND: A honeycomb-like structure in the coronary artery is rarely diagnosed by intracoronary ultrasound or optical coherence tomography. Further, its structural mechanisms and response to interventional therapy remain unknown.CASE PRESENTATION: A 59-year-old Japanese man was referred to our hospital because of acute decompensated heart failure with rapid atrial fibrillation. After receiving anticoagulant therapy, a coronary angiogram revealed a braid-like appearance and an intracoronary ultrasound image confirmed a honeycomb-like structure in the mid left anterior descending coronary artery. We inserted two guide wires into different partitions. Although a balloon angioplasty with a scoring device could not completely fenestrate these partitions, a stent implant was able to completely compress the structure easily.CONCLUSIONS: The honeycomb-like structure of the left anterior descending coronary artery in our patient was suspected to be because of recanalization of a cardiogenic embolism. This structure may have been composed of relatively hard tissues, but was easily compressed by a stent implantation.
