About this trial

ECMO (extracorporeal membrane oxygenation) is a life-saving device, used in intensive care to treat severe respiratory or cardiac failure. However, it carries a high risk of serious life-threatening bleeding.

Bleeding complications have been attributed to coagulopathy triggered either by the underlying pathology or by the extracorporeal circuit itself, as well as excessive or inappropriate anticoagulation initiated to prevent thrombotic complications.

The objective of this cohort is to confirm the interest of the evolution of D-dimers as a prognostic marker of serious bleeding events in patients on veno-venous (VV) or veno-arterial (VA) ECMO, and to determine the threshold.
