Case ReportsRetrohepatic vena cava replacement of hepatic malignancies without using total hepatic vascular exclusion or extracorporeal bypass.
Total hepatic vascular exclusion and venovenous bypass are frequently used surgical procedures when concomitant resection of the inferior vena cava is required during surgery of liver cancer involving the retrohepatic inferior vena cava close to the hepatic veins. However, the duration of total hepatic vascular exclusion is limited due to the risk of hepatic ischemia. Three patients presented with severely compressed inferior vena cava and/or hepatic veins due to liver cancer. ⋯ No graft-related complications occurred, but 2 of the 3 patients showed temporal renal dysfunction associated with renal congestion postoperatively. The surgical procedure described herein is effective for the treatment of retrohepatic inferior vena cava in some patients. However, when the case is complicated by chronic nephropathy or simultaneous nephrectomy is required, venovenous bypass should be performed.
