HEPATECTOMY FOR TUMORS ADJACENT TO THE ROOT OF HEPATIC VEIN

Objective To investigate the possibility of resection of liver tumors adjacent to the root of hepatic veins. Methods Thirty five patients who had undergone hepatectomy for tumors close to the root of hepatic veins in recent three years were analyzed, including 22 cases of hepatocellular carcinoma, 11 cases of haemangioma, one case of FNH and one metastatic carcinoma from lung. Results The resection of the left liver together with segment Ⅷ were performed in 10 cases, the left liver in two cases, segments Ⅶ and Ⅷ in 10 cases, segments Ⅷ, Ⅴ and Ⅳ in eight cases and segment Ⅷ or part of it in five cases. The middle hepatic vein was ligated or resected in nine cases, and end to end anastomosis was done in one case, the right hepatic vein was ligated in one case, and resected in one case. Conclusion The resection for liver tumors close to the root of hepatic vein is safe and feasible with appropriate methods, in spite of the high risk.
