Your doctor will consider certain risks, such as potential bleeding in the brain, to determine if tPA is appropriate for you.

By quickly removing the cause of the stroke, it may help people recover more fully from a stroke. This drug restores blood flow by dissolving the blood clot causing your stroke. Sometimes, tPA can be given up to 4.5 hours after stroke symptoms started. An injection of tPA is usually given through a vein in the arm with the first three hours.

Quick treatment not only improves your chances of survival but also may reduce complications.Īn IV injection of recombinant tissue plasminogen activator (tPA) - also called alteplase (Activase) - is the gold standard treatment for ischemic stroke. The sooner these drugs are given, the better. Therapy with drugs that can break up a clot has to be given within 4.5 hours from when symptoms first started if given intravenously. This may be done with:Įmergency IV medication. To treat an ischemic stroke, doctors must quickly restore blood flow to your brain. An echocardiogram can find a source of clots in your heart that may have traveled from your heart to your brain and caused your stroke.Įmergency treatment for stroke depends on whether you're having an ischemic stroke or a stroke that involves bleeding into the brain (hemorrhagic).

An echocardiogram uses sound waves to create detailed images of your heart. This procedure gives a detailed view of arteries in your brain and neck. Then your doctor injects a dye into your blood vessels to make them visible under X-ray imaging. In this uncommonly used test, your doctor inserts a thin, flexible tube (catheter) through a small incision, usually in your groin, and guides it through your major arteries and into your carotid or vertebral artery. This test shows buildup of fatty deposits (plaques) and blood flow in your carotid arteries. In this test, sound waves create detailed images of the inside of the carotid arteries in your neck. Your doctor may inject a dye into a blood vessel to view the arteries and veins and highlight blood flow (magnetic resonance angiography or magnetic resonance venography). An MRI can detect brain tissue damaged by an ischemic stroke and brain hemorrhages. An MRI uses powerful radio waves and magnets to create a detailed view of your brain. Doctors may inject a dye into your bloodstream to view your blood vessels in your neck and brain in greater detail (computerized tomography angiography). A CT scan can show bleeding in the brain, an ischemic stroke, a tumor or other conditions.

A CT scan uses a series of X-rays to create a detailed image of your brain. You may have several blood tests, including tests to check how fast your blood clots, whether your blood sugar is too high or low, and whether you have an infection. You'll also have a neurological exam to see how a potential stroke is affecting your nervous system. Your doctor will do a number of tests you're familiar with, such as listening to your heart and checking your blood pressure.
