Combinations of arterial and venous endovascular balloon occlusion-providing a new management for traumatic retrohepatic liver- and vena caval injuries?

Traumatic vena caval and retrohepatic injuries often result in severe and life-threatening bleeding and hemorrhagic shock, are difficult to treat and mortality rates are high.
Traditional open surgery methods for hepatic vascular isolation have not been efficient enough. New methods for hepatic isolation are therefor needed. The project aims to explore the potential of endovascular venous balloon occlusion of vena cava inferior, with or without open surgery methods or arterial endovascular occlusion and what hemodynamic and metabolic effects such occlusions might have.
