Overview

Stroke thrombolysis is a medical emergency procedure that breaks up a blood clot that is blocking blood flow to the brain during an ischemic stroke. A vein is used to administer a medicine that dissolves blood clots. Tissue plasminogen activator (TPA) is the most common one. It is only for ischemic strokes, which happen when blood vessels are blocked, and not for hemorrhagic strokes, which happen when blood leaks out. To work, thrombolysis must be given within a certain time frame, usually within 4.5 hours of the first symptoms. Prompt evaluation and treatment are crucial for reducing brain damage and accelerating recovery.

Why It's Done
Stroke thrombolysis is performed to restore blood flow to brain tissue that isn't getting enough oxygen due to a clot. Brain cells start to die within minutes if they aren't treated right away, which can cause permanent damage to the nervous system. Thrombolysis breaks up the clot early, reducing disability, speeding functional recovery, and increasing survival. In stroke care, it is called "time is brain" because it is a time-sensitive, life-saving intervention.

What to Expect
Before thrombolysis, the patient needs to be seen in the emergency room right away. Doctors look at the symptoms, the patient's medical history, and the exact time the symptoms started. A brain imaging scan, usually a CT scan, is done right away to make sure that the stroke is ischemic and not caused by bleeding. They also check your vital signs and do blood tests. During the procedure, the medication that breaks up the clot is given through an IV over a set amount of time. The patient's blood pressure, neurological status, and signs of bleeding are all closely watched. After treatment, the patient is taken to a stroke unit or intensive care unit for close monitoring. Follow-up imaging may be performed to evaluate cerebral recovery and exclude complications.

Recovery & Outlook
How quickly treatment starts and how bad the brain injury was will determine how well someone recovers. Many patients feel much better when thrombolysis is given right away. But you might need rehabilitation therapies, such as speech, physical, and occupational therapy. Getting treatment early makes it much more likely that you will be able to live on your own again and less likely that you will have a long-term disability.
