What Causes Ischemic Stroke?

An ischemic stroke occurs when there is a lack of blood reaching part of the brain. This usually happens when there is a narrowing or blockage of an artery. When a blood clot becomes stuck inside an artery, blood flow is reduced or blocked completely.

Time Means Brain

In the event of an ischemic stroke, time means brain. The longer the clot blocks blood flow to the brain, the more damage it does. The goal of acute stroke treatment is to reduce damage to the brain by removing the clot and restoring proper blood flow as quickly as possible.


Why a Mechanical Thrombectomy?

Soon after arriving to the hospital, the drug tPA is administered into the blood stream in an attempt to break up the clot. If the clot is too large and tPA does not properly dissolve the clot, doctors may perform a mechanical thrombectomy procedure. By physically removing the clot, the surgeon can restore proper blood flow to the brain.
