The mortality of grade V and VI liver trauma fluctuates between 30% and 70%. The atriocaval shunt, described by Shrock et al, in 1968, is a therapeutic option that, after being installed, allows to repair the suprahepatic veins and retrohepatic cava in a bloodless surgical field. Its use requires an experienced and skilled surgeon to obtain survival rates similar to those obtained with other methods. We report two male patients of 17 and 18 years old treated successfully with this technique after suffering a blunt and a penetrating liver trauma by a shotgun, respectively.
