title: [Malignant neoplasms invading into the inferior vena cava. Surgical indications].
abstract: Clinical conditions requiring resection and replacement of the inferior vena cava (IVC) are rare and have included tumors, traumatic or iatrogenic injuries. Intraluminal extension or direct mural involvement of the IVC is seen with a variety of tumors: renal cell carcinomas, adrenal cortical tumors, leiomyosarcomas and pheochromocytomas. Surgical treatment requires tumor resection with simultaneous en bloc resection of the involved IVC. Resection of the lower and middle segments of IVC is possible in nearly all cases and surgical reconstruction is generally made with a polytetrafluoroethylene (PTFE) tube graft. Resection at suprahepatic vein level is indicated only rarely: tumor invasion of the suprahepatic veins require liver transplantation. Venous bypasses have lower patency rates than prosthetic replacement because of the low pressure and lower-flow of the venous system.
