title: Hanging of the hepatic veins septa: a safe control prior and during outflow anastomosis in liver transplantation.
abstract: Inferior vena cava (IVC) preservation during orthotopic liver transplantation (OLT) is known as the "piggyback" technique. The end-to-side anastomosis is constructed between the graft's IVC and recipient's hepatic veins using a Satinsky side clamp applied in a transverse position. To stabilize the large Satinsky clamp and preserve a sufficient vascular stump after hepatectomy and before graft implantation, we propose a technical innovation consisting of hanging the septa between the left and middle hepatic vein and between the middle and right hepatic vein using 2 tapes. This technique showed some advantages when performing the caval outflow anastomosis, representing a further technical refinement of the piggyback end-to-side technique for the implantation on the 3 hepatic veins. From November 2001 to September 2012, we performed 272 consecutive OLT at our institution with the piggyback technique using the hanging of the hepatic veins septa in all cases. In conclusion, the hanging of the 3 hepatic veins septa presented in this study represents a simple, safe and reproducible technique for the outflow anastomosis using the piggyback technique.
