A 43-year-old woman was referred to our hospital for an abnormal shadow on chest X-ray. Computed tomography revealed a tumor with calcification of 9.8 cm in size at the anterior mediastinum. The infiltration into the left brachiocephalic vein and superior vena cava by tumor was suspected. Surgery was performed under a diagnosis of mature teratoma. The tumor was found to adhere firmly to superior vena cava (SVC), left brachiocephalic vein, right phrenic nerve, and the arch of the azygos vein. To ensure the blood flow, an artificial blood vessel was placed between left brachiocephalic vein and right atrium. Then SVC was clamped and the tumor was resected with the part of SVC.
一名43岁女性因胸部X光片出现异常阴影而被转诊至我院。计算机断层扫描显示前纵隔有一个大小为9.8厘米且伴有钙化的肿瘤。怀疑肿瘤已浸润至左头臂静脉和上腔静脉。在诊断为成熟畸胎瘤后进行了手术。发现肿瘤与上腔静脉（SVC）、左头臂静脉、右膈神经和奇静脉弓紧密粘连。为确保血流，在左头臂静脉和右心房之间放置了一根人造血管。然后夹住上腔静脉，将肿瘤与部分上腔静脉一并切除。
