Vienna Hypothermic Oxygenated Machine Perfusion Study

This study is collecting data from liver transplant patients whose donor livers are preserved and transported using a technique called hypothermic oxygenated machine perfusion (HOPE) — a method that keeps the liver at a cool temperature with oxygen flowing through it, which may reduce damage compared to traditional cold storage. **You may be eligible if...** - You are 18 or older - You are scheduled to undergo a liver transplant using a liver preserved with hypothermic oxygenated machine perfusion **You may NOT be eligible if...** - You are pregnant - Your donor liver is only a partial liver (not a whole organ) - The liver's structure is not intact enough to allow perfusion (the process of pumping fluid through it) Talk to your doctor to see if this trial is right for you.
