The pathophysiology, risk, and clinical presentation of Venous Thromboembolisms (VTE) during dry immersion and bed rest

EF 2025-26 · 2025-07-31

Résumé
Recent findings suggest that the venous thromboembolisms (VTE) may occur during spaceflight. Jugular vein thrombosis is rarely reported on Earth, but is associated with relatively poor outcomes. Therefore, there is a need to evaluate the upper body venous system, and the effects of microgravity on venous blood flow, blood viscosity, vessel distension, and inflammation. It is also necessary to provide a better description of the molecular mechanisms by assessing how blood clotting genes are differentially expressed under microgravity. To this end, the proposed research will 1) identify jugular vein status and coagulation changes in spaceflight analogue of dry immersion and bed rest by analysis of blood samples, and 2) investigate the molecular mechanisms that underlie the risk of VTEs by assessing the genes associated with coagulation. The outcome of this project would be a better understanding of the potential underlying mechanisms of VTEs in spaceflight.

Description (French)
Des découvertes récentes suggèrent que des thromboembolies veineuses (TEV) pourraient survenir pendant les vols spatiaux. Les thromboses de la veine jugulaire sont rarement rapportées sur Terre, mais sont associées à des pronostics relativement défavorables. Il est donc nécessaire d'évaluer le système veineux de la partie supérieure du corps et les effets de la microgravité sur le flux sanguin veineux, la viscosité sanguine, la distension vasculaire et l'inflammation. Il est également nécessaire de mieux décrire les mécanismes moléculaires en évaluant l'expression différentielle des gènes de la coagulation sanguine en microgravité. À cette fin, la recherche proposée permettra 1) d'identifier l'état de la veine jugulaire et les modifications de la coagulation lors d'un vol spatial, analogue à l'immersion à sec et au repos au lit, par l'analyse d'échantillons sanguins ; et 2) d'étudier les mécanismes moléculaires à l'origine du risque de TEV en évaluant les gènes associés à la coagulation. Ce projet permettra de mieux comprendre les mécanismes potentiels sous-jacents des TEV lors des vols spatiaux.
