A Trial of Complete Versus Selective HepaticVascular Clamping in Hepatectomy

Intraoperative bleeding remains a major concern during liver resection. Pringle maneuver is the most frequently used method to occlude inflow blood of the liver.However, experimental and clinical studies have shown than even short periods of clamping produce some degree of ischemia-reperfusion injury that can result in hepatocellular damage,this damage being especially important in patients with abnormal liver parenchyma such as steatosis and cirrhosis. The aim of this study was to evaluate whether the use of selective vascular clamping should be generalized to HCC patients and help to reduce the ischemia-reperfusion injury.
