Hyperacute Treatment for Stroke

For the first time, acute stroke became a treatable disorder 20 years ago. Before the advent of thrombolysis (tPA) for acute ischemic stroke all we could offer someone who presented to hospital with a stroke was supportive care.

The injection of tPA(tissue plasminogen activator) into patients who present to hospital with acute stroke has improved the chances of a better recovery after stroke. tPA is a time sensitive treatment that can only be given within the first 4.5 hours after the stroke starts. tPA can only be given to patients with stroke due to a block in the circulation (most strokes), and not to stroke caused by bleeding into the brain. The treatment has to be used with caution and in the right patient as a side effect is bleeding. When used in the appropriate person tPA on average substantially improves the outcome in 1 in 6 people and with a bleeding complication risk of less than 1 in 30.

The most important factor that can lead to a good outcome is to act “FAST”. Know the warning signs of stroke: facial weakness, arm weakness, inability to speak normally. Act quickly, time is brain, call 911!

For some patients with an acute ischemic stroke (stroke due to blockage in the circulation), a new treatment has emerged. For those patients with a large clot in the circulation, sometimes, a catheter can be placed into the clot, and the clot can be removed, to restore the circulation. This treatment is also very time dependent and patients need to act “FAST”.
