RESUMO
The surgical procedure for orthotopic liver transplantation (OLT) is well standardized, and most groups use the retrohepatic caval preservation or piggyback technique to improve hemodynamic tolerance. However, when a discrepancy between the site in the right upper quadrant of the liver recipient and a small graft is present, this technique can provoke a rotation on the axis of the vena cava and cause an occlusion of the suprahepatic vein drainage. This problem can be detected intraoperatively, and several methods have been described to resolve it by placing different devices to correct the position. Early withdrawal may cause the development of clinical hepatic congestion with ascites unresponsive to medical treatment. We present three cases of OLT who developed obstruction of the venous drainage solved intraoperatively with the placement of a Sengstaken-Blakemore tube. As a novelty, prior to the withdrawal of the device, a transjugular hemodynamic study was performed to ensure the correct position of the liver with adequate venous drainage.
