Core Tip
Core tip: Cholangiopathy is a common and devastating clinical complication developing in recipients following donation after circulatory death liver transplantation. Numerous published investigations have attempted to link the hemodynamic instability and hypoxemia following withdrawal of life support to the development of cholangiopathy, without success. Our research indicates that cholangiopathy is linked to the magnitude of hypoxemic, ischemic, and anemic hypoxia transpiring after life support withdrawal and can be represented by a donor hypoxia score. We recommend that the historically utilized nomenclature of ischemic cholangiopathy be replaced using a more physiologic-based and expansive term, hypoxic cholangiopathy.
