The Role of Cardiovascular Surgeons in Oncovascular Surgery for Resection of Retroperitoneal Tumors: A Case Report.

A 43-year-old man diagnosed with a giant retroperitoneal tumor with suspected invasion of the abdominal aorta and inferior vena cava underwent surgery. Complete en bloc tumor resection could be achieved by transection and reconstruction of the abdominal aorta and inferior vena cava. This case highlights the need for aggressive, complete tumor resection when major vessels are invaded. To ensure comprehensive tumor removal, especially in cases requiring manipulation of major vessels, it is imperative to increase the involvement of cardiovascular surgeons in such surgeries. Therefore, widespread promotion of the concept of oncovascular surgery is essential.
