Representative case of left innominate vein injury and repair. (A) Left innominate vein injury and bleeding. (B-D) The bleeding was stopped by suture. A 48-year-old male, preoperative CT scan revealed a mass in the anterior mediastinum with clear boundary, about 40 mm×34 mm in size, indicating a high probability of thymoma. After eliminating contraindications, a robotic portal thymectomy was performed. During the procedure, the left innominate vein injury occurred and the bleeding site was near the confluence of the superior vena cava. The bleeding site was compressed with a gauze piece for hemostasis and then closed with an 8-character pattern suturing using a 4−0 prolene suture
