Unexpected cardio-circulatory arrest during a brain-dead donor organ retrieval.

According to the Maastricht classification category of donation after circulatory death (DCD), type IV DCD refers to brain-dead donors who are re-categorized after unexpected circulatory arrest before donor organ retrieval. Clinical management is challenging, even in intensive care units, where most of this type of organ donation occurs. We report a case of the first successful lung transplantation (LTx) using type IV DCD organ in Taiwan. The recipient's recovery was satisfactory, without acute or chronic organ dysfunction. When unexpected events made the brain-dead donors suffer from sudden onset of cardiac arrest before or during organ donation surgery, immediately switching the retrieval protocol from donation after brain death (DBD) to DCD could expand the donor pool and increase organ supply. The well-prepared and experienced transplant team and prompt protocol switch made this transplant surgery possible.
