A 60-year-old man complained of severe chest pain and was emergently admitted to our hospital with a dignosis of anterior acute myocardial infarction. Emergent coronary angiography revealed significant stenosis in segment 7 and filling defect in segment 11 without flow delay. Haziness was observed in segment 5. Coronary thromboembolism was suspected, but the embolic source or culprit lesion was hard to detect. Intravascular ultrasonography detected ruptured plaque with lipid pooling in segment 5. Stent implantation for segment 5 was performed successfully and the patient had an excellent clinical course. Coronary thromboembolism is rare and intravascular ultrasonography may be useful to detect the culprit lesion.
一名60岁男性主诉严重胸痛，因诊断为前壁急性心肌梗死紧急入院。急诊冠状动脉造影显示7段有明显狭窄，11段有充盈缺损且无血流延迟。5段可见模糊影。怀疑有冠状动脉血栓栓塞，但难以检测到栓子来源或罪犯病变。血管内超声检查发现5段有斑块破裂伴脂质池形成。成功对5段进行了支架植入，患者临床过程良好。冠状动脉血栓栓塞很少见，血管内超声检查可能有助于检测罪犯病变。
