BACKGROUND: Liver resections for tumors adjacent to major hepatic veins often require reconstruction of venous wall defects. We describe a new operative approach that facilitates repair of major hepatic veins during hepatectomies. METHODS: In 3 cases of liver tumors, the resection line had to include partially the wall of the right hepatic vein, middle hepatic vein and left hepatic vein of the preserved liver. The procedure was carried out by employing portal triad clamping combined with extrahepatic occlusion of the hepatic veins. Venous grafts for vascular repair were harvested from the inferior mesenteric vein. RESULTS: In all 3 patients, histology showed tumor-free resection margins. Follow-up of 32 to 42 months revealed no recurrence and excellent liver function. CONCLUSIONS: Combination of selective hepatic vascular exclusion with venous repair techniques, facilitates extensive liver resections in patients with tumors adjacent to the major hepatic veins and maximizes preservation of healthy liver tissue.
