How are Strokes Treated?
There are several treatment options for stroke depending on the cause of your stroke. Emergency treatment for strokes depends on whether you're having an ischemic stroke blocking an artery — the most common kind — or a hemorrhagic stroke that involves bleeding into the brain. If you are having a stroke, or stroke-like symptoms, it’s important to seek immediate treatment.
Stroke Treatment Options
Treatment for an Ischemic Stroke
Tissue Plasminogen Activator (tPA) Injection – Considered the gold standard for ischemic stroke treatment. A tissue plasminogen activator injection (tPA) is given through the vein of the arm and restores blood flow by dissolving the blood clot causing an ischemic stroke. Ideally, this drug is given within three hours after stroke symptoms begin – in some cases 4.5 hours.
Endovascular Procedures – Depending on the severity, sometimes ischemic strokes need to be treated directly inside the blocked blood vessel. Recent large studies have shown that endovascular therapy can be the most effective stroke treatment, depending on the location of the clot and other factors. Forms of endovascular procedures include:
- Catheter tPA delivery to the brain
- Clot removal with stent retriever
Treatment for a Hemorrhagic Stroke
Surgical Treatment – Surgery may be used to repair blood vessel abnormalities associated with hemorrhagic strokes. One of these procedures may be recommended after a stroke – or if an aneurysm or arteriovenous malformation (AVM) or other type of vascular malformation caused your hemorrhagic stroke:
- Surgical clipping to stop blood flow to an aneurysm
- Coiling (endovascular embolization)
- Surgical AVM removal to lower risk of rupture and hemorrhagic stroke
- Stereotactic radiosurgery as a minimally invasive treatment to repair vascular malformations
Endovascular Procedures – Endovascular procedures can treat some hemorrhagic strokes similarly to how the procedure is used for an ischemic stroke. These stroke treatment procedures are far less invasive than surgical procedures.
