Treatment for hepatocellular carcinoma associated with tumor embolus in the inferior vena cava

Abstract

Hepatic resection and removal of the tumor embolus was performed in six patients with hepatocellular carcinoma associated with tumor embolus in the inferior vena cava, without distant metastasis. Hepatic resection was performed in five patients under total hepatic vascular exclusion (THVE) with veno-venous bypass, using a centrifugal force pump and in one patient, under simple THVE without the bypass. In one patient, partial resection of segment VIII was performed, in one, a central bi-segmentectomy, and in four, right hepatic lobectomies were performed. Surgery was safely performed in all the 5 patients under THVE using the centrifugal force pump. One patient who underwent partial hepatic resection under the simple THVE, suffered cardiac arrest during surgery, but resuscitation was successful. Three patients died of reccurence within 1 year. The other three patients survived for 10 months, 2 years and 10 months, and 3 years and 10 months, respectively, after surgery. There were recurrences in the first two, patients, in both, treated by transcatheter arterial embolization, and to date, the third patient is disease-free. Hepatic resection was safely performed in patients with hepatocellular carcinoma associated with tumor embolus in the inferior vena cava, under conditions of THVE using the centrifugal force pump. Prolonged survival can be anticipated, with favorable liver function, in those patients in whom most of the lesion is resected.
