4. Treatment of Brain Ischemia

The only treatment for brain ischemia caused by blood clots is to remove the clot. The gold-standard treatment for ischemic stroke is r-tPA. This IV medication dissolves the clot and improves blood flow, but must be administered within three hours of the start of symptoms.

When a larger vessel is blocked, doctors may mechanically remove it by inserting a catheter with a stent through an artery in the groin and into the brain. The stent opens the blood vessel, so the clot can be removed and the normal blood flow is restored.
