Lasers Blast Clots

WASHINGTON -- Lasers might work to vaporize blood clots in the brain, which would open up new ways to treat stroke patients, doctors said Thursday.

They said tests on five patients suggested the technique may work on some stroke victims.

Dr. Wayne Clark and colleagues at the Oregon Stroke Center in Portland told a meeting of the American Stroke Association in New Orleans the laser had to be used to bust up a clot within eight to 24 hours of a stroke, depending on where the blood clot was.

"It looks very promising," Clark said in a statement.
