[Neoplastic obstruction of the vena cava inferior in general surgery].
Patients with primary or secondary tumoral occlusion of the inferior vena cava are difficult to be managed with safety and success. Nevertheless, their survival may be prolonged by an aggressive surgical approach according to the technical advances of liver transplantation. In fact, it is possible to perform a tumoral exeresis including the inferior vena cava by a total vascular exclusion of the liver (HVE) and a pump-driven veno-venous bypass (ECC). The Authors report the management of 8 patients with inferior caval tumoral involvement (8 M, 1 F, mean age 63.7 yrs). Vascular occlusion was caused by caval leiomyosarcoma (n 1), renal cell carcinoma (n 3), hepatocellular carcinoma (n 1), liver metastases (2 colorectal, 1 renal). Five patients (62.5%) underwent surgical treatment (2 laparotomy, 2 wide nephrectomy with partial caval wall resection in HVE, 1 ex vivo liver resection with caval venoplasty in HVE and ECC). Operative mortality was 40%. Three patients underwent medical treatment (radio-chemotherapy, chemoembolization). Total survival rate was 75% at 3 months, 50% at 6 months, and 25% at 24 months. Two patients (25%) are still alive at 3 months from the diagnosis and at 36 months from the operation.
