At a glance
Thrombolysis for stroke is a treatment that dissolves the blood clot blocking an artery in the brain, restoring blood flow before brain tissue is permanently damaged.
Most strokes happen when a clot (a solid lump of coagulated blood) plugs one of the arteries supplying the brain. Without blood, the affected brain cells begin to die within minutes. A doctor gives a clot-dissolving medicine called a thrombolytic (sometimes called tPA, tissue plasminogen activator) through a drip into a vein. The drug travels to the clot and breaks it apart, allowing blood to flow again and limiting how much of the brain is damaged.
Medical Condition
Thrombolysis is used for ischaemic stroke (a stroke caused by a blocked artery, not by bleeding in the brain) when the patient arrives at hospital quickly enough for treatment to be safe and effective.
- Acute ischaemic stroke (confirmed by CT or MRI scan showing no bleeding)
- Stroke symptoms that began within the treatment window, usually within four and a half hours of the patient last being seen well
- Disabling neurological deficits (weakness, speech loss, or vision problems) severe enough to justify the risk of treatment
- Stroke caused by a clot travelling from the heart (cardioembolic stroke), a clot forming in a small brain artery, or a clot in a larger brain artery
Thrombolysis is not suitable for every patient. Your neurology team will check a detailed checklist before giving the drug. Common reasons it cannot be given include:
- The stroke was caused by bleeding in or around the brain (haemorrhagic stroke), not by a clot
- Too much time has passed since symptoms started, making the risk of bleeding into the brain too high
- The patient has had major surgery, a serious injury, or a previous stroke within the past few weeks
- Active internal bleeding anywhere in the body
- Very high blood pressure that cannot be quickly controlled
- Current use of certain blood thinners that make the brain dangerously vulnerable to bleeding
- A very mild stroke where the risk of treatment outweighs the likely benefit
Risks & Complications
Thrombolysis carries real risks, and the medical team weighs them carefully against the damage an untreated stroke will cause.
- Bleeding in the brain (intracranial haemorrhage): the most serious complication, which can worsen neurological symptoms or be life-threatening
- Bleeding at other sites in the body, such as the gums, skin, or digestive tract
- Allergic reaction to the thrombolytic drug, ranging from a skin rash to a more severe response
- Angioedema (sudden swelling of the tongue or lips), which can interfere with breathing and requires immediate treatment
- Blood pressure fluctuations during or after the infusion
- Reperfusion injury (damage that can paradoxically occur when blood suddenly returns to previously blocked tissue)
- Worsening of neurological symptoms in the first hours, before any improvement is seen
- In a small number of cases, the clot does not dissolve and an additional procedure may be needed
Preparation & Procedure
Because thrombolysis is an emergency treatment, the usual steps of planned preparation do not apply. There is no fasting window, no pre-scheduled medication pause, and no days-ahead consultation. Speed is everything: every minute of delay means more brain cells at risk.
The preparation happens in the emergency department, within the first hour of arrival. Emergency staff will ask the patient or family members the exact time symptoms started, what medications the patient takes (especially blood thinners), any recent surgeries or injuries, and any history of bleeding disorders, previous stroke, or liver disease.
A series of urgent tests is run to confirm the diagnosis and check that thrombolysis is safe. These typically include:
- CT scan of the brain (to rule out bleeding as the cause of the stroke)
- Blood glucose (sugar) level (because low or high blood sugar can mimic stroke symptoms)
- Full blood count (to check platelets, the cells that help blood clot)
- Coagulation tests (to measure how well the blood clots on its own)
- Kidney function tests
- ECG (electrocardiogram, a tracing of the heart's electrical activity) to look for an irregular heartbeat that could have caused a clot
- Blood pressure measurement, taken repeatedly
Once the team confirms the diagnosis and that treatment is appropriate, the procedure itself follows these steps:
- A cannula (a thin plastic tube) is inserted into a vein in the arm.
- A small portion of the thrombolytic drug is given quickly as a bolus (a single fast injection into the drip line).
- The remaining dose is given slowly over about one hour as a continuous infusion.
- Blood pressure is checked very frequently throughout, often every few minutes.
- The patient is monitored for any sign of allergic reaction, bleeding, or change in neurological status.
- A repeat brain scan is usually performed after the infusion to assess the result and check for any bleeding.
Aftercare
After thrombolysis, the patient is moved to a stroke unit or intensive care unit (ICU) for close monitoring, because the first 24 hours are when complications are most likely to appear.
- Blood pressure, heart rate, oxygen levels, and neurological status are checked continuously or very frequently for at least 24 hours.
- Blood thinners and antiplatelet drugs (medicines that prevent clots from forming) are usually withheld for 24 hours after thrombolysis to reduce bleeding risk; the doctor decides when to restart them.
- The patient typically stays in hospital for several days to a week or longer, depending on how severe the stroke was and how quickly recovery progresses.
- Swallowing is assessed by a trained therapist before any food or drink is given by mouth, because stroke can affect the muscles used to swallow safely.
- Physiotherapy (movement and strength exercises), speech therapy, and occupational therapy often begin in hospital as soon as the patient is stable.
- A follow-up brain scan is usually arranged before discharge to confirm the outcome.
- Long-term medications, such as antiplatelet drugs or blood thinners, are prescribed to reduce the risk of a second stroke.
- Rehabilitation continues after discharge, either at a specialist rehabilitation centre or as outpatient sessions, and the length of this phase depends on the degree of recovery needed.
- Lifestyle changes such as quitting smoking, controlling blood pressure, managing blood sugar, and adjusting diet are part of the recovery plan discussed before the patient goes home.
Cost & What Determines It
The total cost of stroke thrombolysis varies widely depending on how severe the stroke is, how long the patient needs to stay in hospital, and what country and hospital class the care takes place in.
- Severity and complexity of the stroke: a mild stroke that responds quickly to treatment results in a shorter stay and fewer additional procedures than a severe stroke requiring intensive monitoring or a follow-up intervention
- Hospital class and country: the same drug and monitoring process costs very differently in a public hospital, a private hospital, or a specialist neurological centre, and costs differ significantly between countries
- Length of stay in the stroke unit or ICU: the number of days in intensive or high-dependency care is often the largest single driver of the total bill
- The thrombolytic drug itself: this drug is expensive and the dose is calculated by body weight, so the medication cost varies by patient
- Imaging: the CT or MRI scans ordered on arrival and after treatment are billed as separate items in most hospitals
- Additional neurological procedures: if thrombolysis alone does not clear the clot, a mechanical thrombectomy (a catheter-based procedure to physically remove the clot) may be needed, adding significantly to the cost
- Rehabilitation services: physiotherapy, speech therapy, and occupational therapy sessions during the hospital stay are usually billed separately from the acute treatment
- Medications on discharge: ongoing prescriptions for stroke prevention add to the long-term cost
A hospital package for stroke thrombolysis typically covers the emergency room assessment, the thrombolytic drug infusion, nursing care in the stroke unit or ICU, and standard monitoring. Brain scans, specialist consultations (such as a cardiologist if a heart cause is identified), rehabilitation sessions, and medications to take home are commonly billed as extras outside the package.
Indonesian patients travelling abroad for medical care should be aware that BPJS Kesehatan does not cover treatment received outside Indonesia, and most Indonesian private health insurance policies exclude overseas treatment as well. This means the full cost is usually paid out of pocket, unless the patient holds an international health insurance policy that explicitly covers overseas care. Before booking or travelling, ask the hospital for a written cost estimate that lists what is and is not included. This makes it much easier to plan finances and avoids unexpected bills after treatment.
Frequently Asked Questions
How many sessions of thrombolysis does a stroke patient need?
Thrombolysis for stroke is a single treatment given once, not a repeated course of sessions. A clot-dissolving medicine is infused through a drip over about an hour, usually within the first few hours after stroke symptoms begin. The timing is critical because the treatment works best when given as early as possible.
What does thrombolysis feel like during the infusion?
Most patients feel little or nothing during the infusion itself, though some notice mild warmth or tingling at the drip site. Because a stroke often affects sensation or awareness, your medical team will monitor you closely throughout and check your neurological signs, meaning how well your brain functions, at regular intervals. Any unusual symptoms are reported to the doctor immediately.
How soon will I know if thrombolysis is working?
Some patients notice improvement within hours of the infusion, such as better speech or movement returning to a weak limb, while others see changes more gradually over the following days. Recovery depends on which part of the brain was affected and how quickly treatment was started. Your doctors will reassess you regularly and may use brain scans to check progress.
How much does thrombolysis for stroke cost?
The cost varies depending on the hospital class, the length of monitoring and stay in a stroke unit or ICU, and the specific clot-dissolving medicine used. Urgent investigations such as brain scans done before and after treatment also affect the total. A written cost estimate from the hospital gives you the most accurate figure for your situation.
