Liver transplantation is the standard treatment for chronic advanced liver disease, whether or not associated with a primary liver tumor. The intraoperative bleeding and the need for blood transfusion, encountered in this major surgery are associated with increased morbidity and mortality. However, this hemorrhagic risk has been drastically reduced in the last 20 years and liver transplants without the use of blood products are now possible. Indeed, improvements in medical and surgical techniques associated with a better understanding of the pathophysiology of the cirrhotic patient have enabled this advance. One of the targeted therapeutic strategies is the control of portal hypertension. Several treatments have been sought, such as the use of splanchnic vasoconstrictors (such as vasopressin) and hypovolemic phlebotomy. These techniques reduce portal pressure and seem to reduce intraoperative bleeding with, even, a protective effect on kidney function. Their single-use or their combination is currently used in certain centers of expertise in liver transplantation. However, the hemodynamic effects of the combination of these 2 treatments on portal pressure has never been demonstrated. In this study, the effect of vasopressin, combined with a hypovolemic phlebotomy, on portal pressure in cirrhotic patients undergoing liver transplantation will be evaluated.
