Imagine suddenly having a severe chest pain, difficulty breathing, or a mouth pulled to one side and unable to speak. How precious is every second at a time like this? The cause of this could be a blood clot in a blood vessel that carries blood to the brain or heart. Today we are talking about a special treatment called "clot-busting," which dissolves such life-threatening blood clots.
What is this blood-thinning treatment?
Simply put, this is a powerful drug treatment that "breaks up" or dissolves and removes potentially life-threatening blood clots. In medical terms, we call this Fibrinolytic therapy or Thrombolytic therapy . What these drugs do is directly dissolve blood clots that can lead to dangerous conditions like a heart attack or stroke, reopening blocked blood vessels, and restoring blood flow.
In what cases is this treatment necessary?
This treatment is mainly used for emergency, serious cases. It is often used to treat the following conditions:
| Medical condition | A simple explanation |
|---|---|
| Heart Attack | Blockage of a blood vessel (coronary artery) that supplies blood to the heart by a blood clot. |
| Stroke | A blood vessel supplying blood to the brain is blocked by a blood clot. |
| Pulmonary Embolism | A blood vessel supplying blood to the lungs is blocked by a blood clot. |
| Deep Vein Thrombosis (DVT) | A blood clot, usually in a deep vein in the leg. |
| Other cases | Blockage of other arteries in the body, blockage of tubes used for dialysis, or blockage of a surgically placed bypass. |
Why is time so important?
Time is of the essence in this treatment, especially in the case of stroke. Taking this medicine within 3 to 4.5 hours of the onset of symptoms can significantly reduce the risk of permanent brain damage. This means that it is extremely important to start this treatment within 30 minutes of the patient being brought to the hospital's emergency treatment unit (ETU). The sooner the treatment is started, the better the results.
Is everyone suitable for this treatment?
No. Because this is a very strong medicine, it cannot be given to people with certain risk factors. When you are admitted to the hospital, the medical team will perform the necessary tests to determine if you are suitable for this treatment.
Cases that may be unsuitable for this treatment
This treatment is not usually given to someone with the following conditions:
| Possible reason for ineligibility for treatment |
|---|
| If you are over 75 years old |
| If you have had a previous brain bleed |
| If you are currently taking blood-thinning medication |
| If you have had a stroke within the last three months |
| If you have active bleeding anywhere in the body or have recently had surgery/serious accident |
| If you have been diagnosed with a brain tumor |
| If you are pregnant |
| If you have uncontrolled high blood pressure |
| Having a very low platelet count |
This list is not exhaustive. There may be other factors that affect your condition. Therefore, the final decision should be made by your doctor.
How the treatment is done
Before and during treatment
Because this is an emergency, you will be admitted directly to the intensive care unit (ICU) . The medical team will monitor your heart rate and blood pressure continuously. The medication will be given through an IV line in your arm or a very thin tube (catheter) that is guided to the site of the clot. During treatment, tests such as a CT scan or MRI scan will be used to see if the clot is dissolving.
Sometimes, in addition to this treatment, another method called Mechanical Thrombectomy can be used. This involves physically breaking up the blood clot using a catheter and removing it through the urine .
After treatment
After treatment is successful, doctors check to see if any parts of the clot remain. Additional treatment may be needed. For example, stent placement, balloon angioplasty, or open surgery may be necessary. Anticoagulants, such as Warfarin or Heparin , are often prescribed to prevent future clots.
What are the benefits and risks of the treatment?
The main advantage is that this treatment can dissolve the blood clot and restore blood flow to the heart, brain, or other vital organs. This can prevent life-threatening damage and minimize possible long-term damage.
The main risk is bleeding . This can occur in different ways.
- Bleeding from the cannula insertion site
- Nosebleed
- Blood in the urine
- Blood in the stool
- Excessive vaginal bleeding in women
- A very rare but very serious risk is brain bleed .
But remember, for most people, the benefits of this treatment far outweigh the risks. Your doctor will decide whether this is right for you.
Treatment is not always 100% successful. In about 25% of cases, the blood clot may not be completely dissolved. In such cases, other treatment methods may have to be resorted to.
How long does it take to heal?
Recovery time varies from person to person. You will usually need to stay in the hospital for at least a day after treatment. However, if your condition is serious, you may need to stay in the hospital for longer.
If you experience symptoms such as excessive bleeding, unbearable pain, or fever after treatment, call your doctor immediately or notify the hospital where you received treatment.
