SALT LAKE CITY (AP) _ It's an anti-clotting drug that's currently used to treat strokes and heart attacks.
And now, researchers say it can also restore the flow of blood to frostbitten fingers and limbs -- reducing the need for amputation.
Doctors at the University of Utah conducted the research on a small sample of patients. They hope it marks the start of a move beyond the limited treatments that have existed for frostbite.
Patients at the university's burn center who received the treatment were more likely to keep their frostbitten fingers and toes than patients without the drug.
The study is included in the Archives of Surgery medical journal.
