Magic Number “4.5”
The quicker you recognize the signs of stroke and seek medical care, the higher your likelihood is of having a successful recovery. The magic number is 4.5 hours. This is the golden period of stroke. 1) Within 4.5 hours after stroke symptoms begin The doctor will order a MRI scan in order to see a detailed view of the brain and the damage. The gold standard treatment for ischemic stroke is an injection of recombinant tissue plasminogen activator (rtPA). This potent clot-busting drug ideally is given 4.5 hours after stroke symptoms begin. This drug restores blood flow by dissolving the blood clot causing your stroke, and it may help people who have had strokes recover more fully. 2) For patients who come to the hospital later than 4.5 hours but within 24 hours Doctors may use a catheter to maneuver a device into the blocked blood vessel in your brain and trap and remove the clot. This procedure is particularly beneficial for people who cannot receive rtPA injection. An interventional radiologist will evaluate the patient whether this treatment option is appropriate.
