BACKGROUND: Selective hepatic vascular exclusion (SHVE) is an effective hepatic vascular exclusion in controlling both inflow and outflow without interruption of caval flow, as it combines Pringle maneuver with extrahepatic selective occlusion of hepatic veins. But SHVE has not been widely used due to difficulty in extrahepatic dissection of hepatic veins. When the tumor is very close to the roots of the hepatic veins, dissecting the posterior wall of the hepatic vein may lead to rupture and massive bleeding of the hepatic vein. With our experience, clamping hepatic veins with Satinsky clamps is a safer and easier occlusion method by which the posterior wall of the hepatic veins does not need to be separated and encircled. In this report, we compared the results of selective hepatic vascular occlusion with tourniquet and Satinsky clamp for major liver resection involving the roots of the hepatic veins. METHODS: Between January 2003 to June 2006, 180 patients who underwent major liver resection with SHVE were divided into two groups according to different methods of hepatic vascular occlusion: occlusion with tourniquet (tourniquet group, n = 95) and occlusion with Satinsky clamp (Satinsky clamp group, n = 85). In the tourniquet group, the hepatic veins were encircled and occluded with tourniquet. In the Satinsky clamp group, the hepatic veins were not encircled and clamped directly by Satinsky clamp. RESULTS: Intraoperative and postoperative consequences of the patients were analyzed. The dissecting time for each hepatic vein was significantly shorter in the Satinsky group (6.2 +/- 2.4 min vs 18.3 +/- 6.2 min) than in the tourniquet group. In the tourniquet group, five hepatic veins (one right hepatic vein and four common trunk of left-middle hepatic veins) could not be dissected and encircled because the tumors involved the cava hepatic junction, and another common trunk of the left-middle hepatic vein had a small rupture during the dissection. These six patients then received successful occlusion with Satinsky clamp. There was no difference between the two groups regarding the operation duration, ischemia time, intraoperative blood loss, and postoperative complication rate. CONCLUSION: Both methods of the hepatic vein occlusion have the same effect on controlling hepatic vein bleeding, but occlusion with Satinsky clamp is safer, easier, and consumes less time in dissecting.
