Validation of Functional Assessment for Liver Resection Considering Venous Occlusive Area after Extended Hepatectomy

Previous studies demonstrated that liver function in a veno-occlusive region is approximately 40% of that in a non-veno-occlusive region after hepatectomy with excision of major hepatic vein. We validated the preoperative assessment of future remnant liver (FRL) function based on 40% decreased function of the veno-occlusive region. Sixty patients who underwent hepatectomy with excision of major hepatic vein were analyzed. The FRL functions of...
