Brief summary
The existence of AAS coagulopathy has been reported, related to blood contact with the walls of the non-endothelialized false lumens. It is likely that endothelial dysfunction generated by vascular lesions may largely contribute to the development of coagulopathy, such as described in trauma-induced coagulopathy. This endotheliopathy of the AAS has never been evaluated. The coagulopathy of AAS and more specifically the endotheliopathy are poorly described and therefore have no standardized treatment. The main objective of this study is to describe the coagulopathy
Detailed description
Acute aortic syndromes (AAS) result from an organic lesion of the aortic wall. The various symptoms of AAS, mainly the acute chest pain, leads to a breakdown of the intima or the media of the aorta. This syndrome is made of three entities : aortic dissection (DA), intra-mural hematoma (HIM) and penetrating atherosclerotic ulcer (PAU). Surgery is a complex emergency treatment of choice. Patients suffering from these pathologies die mainly from hemorrhagic shock due to haemostasis disorders, which requires massive transfusion. The existence of AAS coagulopathy has been reported, related to blood contact with the walls of the non-endothelialized false lumens. It is likely that endothelial dysfunction generated by vascular lesions may largely contribute to the development of coagulopathy, such as described in trauma-induced coagulopathy. This endotheliopathy of the AAS has never been evaluated. The coagulopathy of AAS and more specifically the endotheliopathy are poorly described and therefore have no standardized treatment. The main objective of this study is to describe the coagulopathy and more specifically the endotheliopathy of AAS, in particular assessing coagulation disorders, hyperactivation of fibrinolysis, quantitative or functional platelets disorder and endotheliopathy. The secondary objective is to determine the factors associated with this coagulopathy. This includes 1 / assessment of potential risk factors for coagulopathy, 2 / the prognosis of coagulopathy by assessing the relationship between coagulopathy and transfusion requirements and mortality.
