Researchers are studying bleeding and clotting risks during and after liver transplant surgery. This observational study aims to understand these risks better by examining various factors throughout different surgery phases, using new predictive methods like machine learning. The goal is to improve how bleeding and post-surgery blood clotting are managed in liver transplant patients in metropolitan France. The study does not involve any treatment or intervention. It will observe adult patients undergoing liver transplant surgery, recording data on bleeding, blood transfusions, and clotting events. Researchers will track blood product use and hemostatic tests during surgery and up to 30 days afterward. The study will document the use of medicines to prevent clotting and any related complications. Participants will be monitored closely with blood tests and clinical assessments during surgery and for 30 days after. Researchers will collect detailed information about blood loss, transfusions, and thrombotic events. They will also analyze how various treatments affect bleeding and clotting outcomes. The main measure is the number of red blood cell transfusions during surgery. Participation length varies by patient needs and surgery timing.
