Subxiphoid Robotic Thymectomy with Superior Vena Cava Resection.

Area of Science:

• Thoracic Surgery
• Robotic Surgery
• Surgical Oncology

Background:

• Thymectomy is a key procedure for thymic malignancies and myasthenia gravis.
• Superior vena cava (SVC) resection is sometimes necessary for advanced thymic tumors but typically requires open surgery.
• Minimally invasive techniques for complex thymic resections involving SVC are limited.

Purpose of the Study:

• To describe a novel surgical technique for subxiphoid robotic thymectomy combined with SVC resection.
• To demonstrate the feasibility of robotic-assisted SVC reconstruction during thymectomy.
• To present an alternative to open surgery for complex thymic tumors requiring SVC resection.

Main Methods:

• A subxiphoid robotic approach was utilized.
• A dual-cannulation strategy was employed for cardiopulmonary bypass and blood management.
• En bloc resection of the tumor, SVC, thymus, pericardium, and part of the right lung was performed.
• Reconstruction focused on the right brachiocephalic-SVC anastomosis.

Main Results:

• The described technique successfully enabled robotic-assisted thymectomy with combined SVC resection and reconstruction.
• The procedure was completed using a minimally invasive subxiphoid incision.
• This approach facilitates SVC replacement, expanding options beyond traditional open surgery.

Conclusions:

• Subxiphoid robotic thymectomy with SVC resection is a viable and potentially advantageous alternative to open surgery.
• This technique offers a minimally invasive option for managing advanced thymic tumors requiring SVC involvement.
• Robotic assistance enhances precision and potentially improves outcomes for complex thoracic procedures.
