RESUMO
BACKGROUND: Livers from controlled donation after circulatory death (cDCD) with very prolonged warm ischemic time (WIT) are regularly transplanted after abdominal normothermic regional perfusion (aNRP) plus ex-situ machine perfusion (MP). Considering aNRP as in-situ MP, we investigated whether the results of a pilot experience of extended criteria cDCD liver transplantation (LT) with prolonged WIT, with aNRP alone, were comparable to the best possible outcomes in low-risk cDCD LT. METHODS: Prospectively collected data on 24 cDCD LT, with aNRP alone, were analyzed. RESULTS: The median total and asystolic WIT were 51 and 25 min. Measures within benchmark cut-offs were: median duration of surgery (5.9 h); median intraoperative transfusions (3 units of red blood cells); need for renal replacement therapy (2/24 patients); median intensive care stay (3 days); key complications; overall morbidity, graft loss, and retransplantation up to 12 months; 12-month mortality (2/21 patients). The median hospital stay (33 days, due to logistics) and mortality up to 6 months (2/24 patients, due to graft-unrelated causes) exceeded benchmark thresholds. CONCLUSIONS: This pilot experience suggests that livers from cDCD with very prolonged WIT that appear viable during adequate quality aNRP may be safely transplanted, with no need for ex-situ MP, with considerable resource savings.

A 21-year-old patient has been treated in emergency with venovenous extracorporeal membrane oxygenation after severe thoracic trauma causing severe air leak and haemothorax. The extracorporeal assistance was managed without heparin for 10 days till the full recovery of the lung, and no side-effect was recorded.

Intracaval buffle repair of scimitar syndrome is classically performed under deep hypothermic circulatory arrest or using low-flow modalities of cardiopulmonary bypass with peripheral cannulation. We propose an alternative perfusion approach to the procedure using total intrapericardial cannulation under full-flow normothermic cardiopulmonary bypass.
