Why the study?
In a patient with superior vena cava syndrome from invasive thymoma, endovascular therapy was not feasible because the superior vena cava appeared totally occluded and stenting risked tumor embolism to the pulmonary arteries.

Demonstrates successful open surgical resection of invasive thymoma causing superior vena cava syndrome, indicating a viable option when endovascular therapy is unfeasible.
Here we describe a case of open surgery for superior vena cava syndrome due to invasive thymoma. An 85-year-old woman presented with facial swelling and exertional dyspnea. Computed axial tomography revealed a thymoma in the mediastinum, extending to the superior vena cava, right atrium, and bilateral brachiocephalic veins. Endovascular therapy did not seem feasible because superior vena cava appeared totally occluded, and stenting could cause tumor embolism to the pulmonary arteries. Open surgery facilitated macroscopically complete and successful tumor resection. If long-term survival seems possible, open surgery could be a viable treatment option for superior vena cava syndrome that is ineligible for endovascular therapy.

Kawaida et al. (2022) conducted a case report in Superior vena cava syndrome due to invasive thymoma (n=1). Open surgical tumor resection and vascular reconstruction with polytetrafluoroethylene grafts and bovine pericardium was evaluated on Macroscopic tumor resection, central venous pressure reduction, and graft patency.
