- A patient undergoing radical retroperitoneal lymphadenectomy for metastatic embryonal cell testicular carcinoma is presented. Tumor resection required removal of the inferior vena cava due to transmural invasion. The inferior vena cava was replaced using externally stented polytetrafluoroethylene (PTFE) graft. Patency was documented by postoperative Doppler studies, duplex scanning, and computed tomographic scanning. Stented PTFE is currently the graft of choice for inferior vena caval replacement.
