How long after stroke can you take streptokinase?
The Australian Streptokinase Trial was a randomized, double-blind, placebo-controlled trial of intravenous streptokinase (1.5 million U) given within 4 hours of stroke. 3 On the basis of an interim analysis of 300 persons (72 treated less than 3 hours after stroke), the trial's safety committee recommended that recruitment of persons seen more than 3 hours after stroke onset be halted because of a significant increase in adverse experiences among those given streptokinase. Subsequently the entire trial was stopped. Among persons treated 3 to 4 hours after stroke, unfavorable outcomes (death or death/severe disability) were significantly more frequent among persons treated with streptokinase (Level of Evidence I) (Table 2 ).
How long does it take to administer r-TPA?
1. Intravenous r-TPA (0.9 mg/kg, maximum 90 mg) with 10% of the dose given as a bolus followed by an infusion lasting 60 minutes is recommended treatment within 3 hours of onset of ischemic stroke (Grade A recommendation). The benefit of intravenous r-TPA for acute ischemic stroke beyond 3 hours from onset of symptoms is not established. At this time intravenous administration of r-TPA for a person who has had a stroke more than 3 hours earlier cannot be recommended outside the clinical investigation setting. Intravenous r-TPA is not recommended when the time of onset of stroke cannot be ascertained reliably, including strokes recognized upon awakening.
What is the most feared complication of thrombolysis?
Bleeding is the most feared complication. Hemorrhagic events generally are divided into those that directly affect the central nervous system and those that involve other organs. The treatment of thrombolysis-related bleeding is guided by (1) the location and size of the hematoma, (2) the likelihood that the bleeding can be controlled mechanically, (3) the risk of neurological worsening or death, (4) the interval between administration of the drug and the onset of hemorrhage, and (5) the thrombolytic drug used. Information is scarce to guide recommendations about treatment of hemorrhagic complications of thrombolytic therapy (Levels of Evidence III through V).
Is thrombolytic drug superior to other drugs?
There is no evidence that one thrombolytic drug is superior to others in terms of rates of recanalization or safety when used for local or intra-arterial thrombolysis. 3. The usefulness of supplementary techniques to speed recanalization with intra-arterial administration of thrombolytic drugs is not determined.
Can intra-arterial thrombolysis reopen occlusions?
1. Intra-arterial thrombolysis can reopen arterial occlusions (Levels of Evidence II through V). Rates of recanalization are lower for occlusions of the internal carotid artery or basilar artery than for occlusions of branches of the middle cerebral artery.
Can r-TPA be used for stroke?
There are no data concerning the use of r-TPA for the treatment of acute ischemic stroke in neonates, infants, or children.

One study suggests that a dose of 0.5 mg/kg should be used in children. 51

- The symptoms of a thrombotic stroke vary, depending on which area of the brain is affected. That is because different areas of the brain are responsible for different functions. For example, different areas of the brain control movement, sight, speech, balance and coordination. Symptoms can include: 1. Headache 2. Dizziness or confusion 3. Weakness or paralysis on one …
Prognosis
- To diagnose a stroke, your doctor will need an image of your brain. Two different brain imaging tests can be useful. They are a computed tomography (CT) scan and magnetic resonance imaging (MRI) scan. Usually the CT scan is done first because it can be obtained more quickly than an MRI. If the CT scan shows bleeding in or around the brain, then you have had a hemorrh…
Further Information
- Recovery depends on how long blood flow to the brain is blocked. If blood circulation in the brain is restored within minutes to a few hours, the person can recover rapidly, within hours to a day. For a small thrombotic stroke (lacunar stroke), symptoms often improve within a few days, even if the blood clot has not dissolved. When the blood supply is interrupted for longer periods of time…
