From the State Journal:
When Kent Wittwer couldn’t wake up his wife last month, he called 911.
Jill Wittwer, 59, was rushed to UW Hospital, where doctors said she had a stroke. Using a stent device inside a catheter, they removed a clot blocking blood flow in her brain.
Until recently, patients couldn’t get the procedure unless doctors knew the stroke happened within six hours. But two national studies, one involving patients at UW Hospital, expanded the window to 24 hours — a potential life-saver for people who have strokes during sleep, as Wittwer did.
