Concomitant aortic and vena caval reconstruction associated with germ-cell tumor resection with creation of a new venous bifurcation.

Aortic and vena caval reconstruction associated with tumor resection is very rare. We describe a 22-year-old man with a retroperitoneal metastasis from a germ-cell tumor previously treated with chemotherapy who presented with a huge mass involving the infrarenal aorta and the inferior vena cava. He underwent retroperitoneal lymph node dissection with concomitant aortic and caval reconstruction that included customization of a new caval bifurcation. His postoperative recovery was uneventful, and he remained well 36 months after the operation. Complementary follow-up imaging examinations demonstrated that the aortic and venous interposition grafts were patent and that there was no local or distant disease recurrence.
