Sue McNeely of Bothell, Washington, hasn't driven since February 10, when she had a stroke in rush-hour traffic on Interstate 405.

A state trooper responded and recognized the emergency. McNeely was taken to Harborview Medical Center, which has the state's only comprehensive stroke center.

Chief of Neurological Surgery Dr. Louis Kim performed a procedure to remove a blood clot blocking blood flow to the part of her brain that controls strength and movement on the left side of her body.  "It can immediately take a patient with acute stroke, like Mrs. McNeely and restore them to normal blood flow and normal function again, in just moments," he said.
