Concern of Venous Thromboembolism

mission medical experiment
Astronauts Kathryn D. Sullivan and Bruce McCandless II, mission specialists, work together to perform one of the mission’s medical experiments. The experiment is Detailed Supplementary Objective (DSO) 462, Non invasive Estimation of Central Venous Pressure During Spaceflight. Sullivan applies a gel substance to a transducer which will be placed on McCandless’ jugular vein to collect the sought data. The cable links to a data recorder.

Stagnant or reverse flow in the internal jugular vein has been observed in 6 of 11 crew members (55%) tested in-mission on approximately flight day 50; one crewmember was found to have an occlusive internal jugular vein thrombus requiring treatment in-mission. This is an emerging finding and has potential impacts on flight participants with cardiovascular conditions.
