While that may be par for the course for most doctors, what made this case unique was that Moll’s patient was 250 miles above Earth. According to WRAL, the professor of medicine was contacted by NASA when an astronaut aboard the International Space Station was diagnosed with a blood clot in his jugular vein. Moll, who has published multiple studies on blood clots, was at the school when the unexpected call came in. “So I picked up the phone, and NASA was on the phone and said it was urgent,” he recalled to the news station. “It was surprising, it was an honor,” Moll added. “I was curious to see where that would lead.” The agency had never experienced a blood clot problem in space before and had no protocol on how to deal with one, WRAL reported. “So all the decisions that had to be made were best guesses,” Moll said. The professor worked with a team of NASA doctors to devise a spur-of-the-moment treatment for the astronaut, whose name was not publicized for privacy reasons.

While blood clots are usually treated with anticoagulants, according to Cleveland Clinic, Moll was unsure if the medication would work the same in space. “I needed to weigh the risk-benefit of starting a blood thinner or not starting a blood thinner,” he recalled. Fortunately, the space station had blood thinners on hand. While they only had a small supply, it was enough to get the job done. Earth from space.

It was actually without any delay. This is amazing because the ISS moves at 17-18,000 miles an hour.” The astronaut has since returned to Earth and has recovered.
