title: Total replacement of the suprarenal inferior vena cava with an expanded polytetrafluoroethylene tube graft in 2 patients with tumor thrombi from renal cell carcinoma.
abstract: Total replacement of the suprarenal inferior vena cava using an expanded polytetrafluoroethylene vascular graft was successful in 2 renal cell carcinoma patients with extended tumor thrombi densely adherent to the vena caval wall. Right radical nephrectomy in 1 patient and enucleation of the tumor in the solitary right kidney were performed concomitantly. Both patients are well without tumor recurrence and with good vena caval patency 14 and 6 months postoperatively. This procedure could be a safer mode of operation in cases of extended vena caval involvement by malignant tumors. Total reconstruction of the inferior vena cava enables more radical resection of the tumor.
