Abstract

Renal cell carcinoma (RCC) with tumor thrombus (TT) may extend into and, in rare cases, actually invade the inferior vena cava (IVC). Techniques of IVC reconstruction after removal of the RCC, TT, and infiltrated portion of the IVC have not been well documented. Methods A ringed polytetrafluoroethylene (PTFE) interposition graft along with an IVC filter placed within the graft (to prevent the development of pulmonary emboli) was used for patients who underwent surgical resection of RCC with TT extending into and directly invading the wall of the IVC. Demographic information about these patients along with their pathology reports, surgical procedures, and patency of the PTFE graft was obtained and described. Results Four male patients were identified as having RCC and TT with histologic invasion of the IVC requiring IVC dissection and replacement with a PTFE graft (as described above); their TT levels were II, IIIa, IIIc, and IV, respectively. Patient ages were 58, 65, 58, and 51 years and tumor sizes were 7.5, 7.5, 15.0, and 6.5 cm, respectively. These patients were followed for 36, 24, 32, and 48 months, respectively. At last follow-up, each patient had a patent IVC graft, and none of them developed any pulmonary emboli post-operatively. Conclusions Ringed PTFE interposition graft along with an IVC filter deployed inside the graft appears to be a safe vascular conduit for IVC reconstruction after surgical resection of RCC with TT directly invading the IVC.
