Astronauts get blood clots, bizarre blood flow



According to a shocking report by NASA scientists, blood flow in the upper bodies of astronauts can come to a standstill and even reverse.

The study could have some important implications for longer space travel, as we still try

The study examined periodic ultrasound scans of 11 healthy astronauts who occupied the International Space Station.

The results were alarming: blood flow had either stagnated or, conversely, left inner jugular vein, a large blood vessel at the side of the neck, with seven crew members. The tests also revealed a clot and a partial clot on two crew members returning to Earth.

An article from the study was published Wednesday in the journal JAMA Network Open .

"This was an unexpected finding," said Michael Stenger, senior author and manager at NASA's Johnson Space Center, opposite NBC News . "We did not expect congestion and reflux. That is very unusual. On Earth you would immediately suspect a massive blockage or a tumor or something similar. "

And that could have serious effects on astronauts' health.

"If you get a clot in the internal jugular vein, the clot could migrate into the lungs and cause pulmonary embolism ̵
