A 76-year-old woman with a 2-week history of dyspnea on exertion was admitted to our hospital. A computed tomography scan showed a 70-mm diameter aortic arch aneurysm containing a large thrombus that was compressing the pulmonary artery. Echocardiography showed severe pulmonary stenosis and no shunt flow. Operative findings revealed an aneurysmal thrombus protruding into the lumen of the pulmonary artery through a foramen. A ductus arteriosus aneurysm was diagnosed. After the thrombus removal, arch replacement and ductus closure with a prosthetic patch were performed. Histological examination showed that the thrombus had no vascular components. The patient's symptoms were relieved, and she was discharged.
一名76岁女性，有2周劳力性呼吸困难病史，入住我院。计算机断层扫描显示直径70毫米的主动脉弓动脉瘤，内有巨大血栓，压迫肺动脉。超声心动图显示重度肺动脉狭窄，无分流。手术所见显示一个动脉瘤性血栓通过一个孔突入肺动脉腔。诊断为动脉导管动脉瘤。清除血栓后，进行了主动脉弓置换及用人工补片封闭动脉导管。组织学检查显示血栓无血管成分。患者症状缓解后出院。
