Abstract :
In chronic obstructive pulmonary disease (COPD) patients extracorporeal CO2 removal (ECCO2R) has been associated with both hemorrhagic and thrombotic complications [1], which could be related to an endothelial dysfunction promoted in part by extracorporeal life support [2]. Moreover, endothelial dysfunction is a hallmark of severe COPD: an imbalance between repair capacity and endothelial damage has been reported in stable patients [3], with a changing profle during acute exacerbations [4]. We planned to rigorously study these points using a formalized ECCO2R register (NCT02965079) combined with a study project (Hector: Hemostasis and ECCO2R).
