The incidence of coronary artery aneurysms is about 1 to 2%, with clinical course dependent on the size of the aneurysm. A case of moderate-size aneurysm in the proximal left anterior descending coronary artery with stenosis at both edges is presented. This was interrogated with intravascular ultrasound (IVUS), and based on the patient's presentation, a single stent, size-matched 1:1 to the proximal reference, was placed across the aneurysm and both lesions. Post-implantation IVUS demonstrated residual stenosis and minimal change in the neck size of the aneurysm. At 4 months, there was no thrombosis or in-stent restenosis, and the aneurysm was almost completely resolved.
冠状动脉瘤的发生率约为1%至2%，其临床病程取决于动脉瘤的大小。本文报告一例左前降支近端中等大小的动脉瘤，两端均有狭窄。采用血管内超声（IVUS）对其进行检查，并根据患者的表现，植入一枚与近端参考血管1:1尺寸匹配的单支架，横跨动脉瘤及两处病变部位。植入后IVUS显示仍有残余狭窄，动脉瘤颈部大小变化极小。4个月时，未出现血栓形成或支架内再狭窄，动脉瘤几乎完全消退。
