INTRODUCTION: Advanced-stage thymic malignancies are a heterogeneous group of mediastinal tumors that include thymoma and thymic carcinoma infiltrating the surrounding thoracic structures. When the tumor infiltrates the superior vena cava (SVC), radical resection can be selectively achieved via en bloc SVC resection and its prosthetic conduit replacement. We herein report a case of SVC replacement for thymic carcinoma en bloc radical resection.
CASE PRESENTATION: A 75-year-old Japanese man presented at our hospital due to progressive dyspnea and edema of his face and upper extremities. CT showed a 55 × 40 × 38-mm tumor located at the anterior mediastinum lesion. This tumor had invaded the superior vena cava and both brachiocephalic veins. We performed surgical resection for the thymic carcinoma located at the mediastinum that invaded the superior vena cava and both brachiocephalic veins. The surgery was performed through a full median sternotomy and transmanubrial approach without using an artificial heart and lung. The tumor involved the SVC, right brachiocephalic vein (RBCV) and left brachiocephalic vein (LBCV). We performed SVC replacement for thymic carcinoma en bloc radical resection.
DISCUSSION: This report has two important implications. First, a venovenous shunt (VVS) from the distal LBCV to the right auricle was very useful and safe before performing an SVC complete clamp. The second implication of our study was that using a PTFE with a large inner diameter may prevent thrombus occlusion.
CONCLUSIONS: We experienced SVC replacement for thymic carcinoma en bloc radical resection. We were able to safely performed this surgery using our usual approach.
