What are some new developments in the treatment of acute stroke?

Rafael Alexander Ortiz

The new advances in the treatment of acute ischemic stroke are targeted to faster and more reliable recanalization (opening) of the occluded arteries in the brain.  There is a new generation of stentrievers to open the arteries.  These are devices made of nitinol (combination of different metals) that are introduced to the body through a catheter from the artery that takes blood to the leg (angiogram) and are navigated to the occluded arteries of the brain.  Stentrievers are based on the concept of a stent that is attached to a wire and used to achieve immediate flow in the previously affected artery and at the same time for retrieval (removal) of the clot to prevent re-occlusion. 

The first randomized study of one of these devices was just completed in the US and demonstrated significant improvement in recanalization and outcome when compared to the previously designed technology.
