Canadian stroke trial delivers dramatically improved patient outcomes
Feb. 11, 2015
Results from an international trial promise to revolutionize stroke care with a new procedure. The procedure is based on novel use of technology that gives researchers the ability to remove brain clots faster—lowering stroke patients’ disability and death rate.
“This is the most significant and fundamental change in acute ischemic stroke treatment in the last 20 years. These results will impact stroke care around the world,” says Dr. Michael Hill, an Alberta Innovates – Health Solutions (AIHS) funded researcher, neurologist and professor in the Cumming School of Medicine.
The trial included patients who arrived for treatment within 12 hours of their stroke. One important goal was to have patients’ treatment completed within 90 minutes.
We set very aggressive time targets and in my mind it’s remarkable that our 22 sites across the world were able to do this,” said Dr. Hill.
Doctors were able to remove clots using a removable stent and new brain imaging (X-ray). Removing the clot restores blood flow to the brain much quicker than using the traditional drug therapy that dissolves clots.
