Have you ever heard someone say, "A blood clot is stuck"? This can be very dangerous. Think of the blood vessels in our body as a system of pipes. If a clot, called a `thrombus`, forms and gets stuck anywhere in these pipes, the blood flow through them is completely stopped. If this happens in a major vein that supplies blood to the brain, heart, or an arm or leg, that organ can be damaged, possibly even life-threatening. In such an emergency, we are going to talk about a very important medical treatment that can save a life today.
Simply put, what is Thrombectomy?
Thrombectomy is the process of removing a blood clot that is stuck inside one of our blood vessels (arteries or veins) through surgery or a similar specialized procedure. It's like removing a piece of dirt stuck in a water pipe and letting the water flow again.
These blood clots can form in many places in our bodies. They are most commonly found in the legs, arms, intestines, brain, lungs, and heart. Sometimes these blood clots need to be removed quickly, within a few hours. Otherwise, they can cause permanent damage to the affected organ or even be life-threatening.
Who really needs this treatment?
Usually, when a blood clot forms, there are medications that are given to dissolve it. We call them `anticoagulants` (blood thinners) and `thrombolytics` (blood clot-dissolving medications). But sometimes, these medications alone cannot remove the clot, or there are cases where medication is not available. That's when doctors decide to perform a Thrombectomy.
This treatment is mainly needed for:
- If there is a risk of harm to life .
- If there is a risk of a blood clot (thrombus) breaking away from its original location and traveling through the bloodstream to become lodged elsewhere in the body (for example, in the lungs) (an `embolus`).
- If there is a risk of permanent damage to the relevant organ or tissue.
This method is extremely important to quickly restore blood flow to the brain or heart, especially in emergency situations such as stroke and heart attack.
In what cases is a thrombectomy not performed?
This treatment is not done for every blood clot. In some cases, there are reasons why this cannot or should not be done. Let's see what they are.
| Reasons not to perform a thrombectomy | A simple explanation |
|---|---|
| Difficulty reaching the site of the blood clot | Some blood vessels are in very deep, complex places. It's difficult to get instruments into such a place. |
| Having a clot in a very small blood vessel | Devices cannot be inserted into very small veins. They can be damaged. |
| Cureable with medicine | If it can be controlled with blood thinners, there's no risk of surgery. |
| Having blood clotting disorders | Some people have congenital blood disorders, and surgery can be dangerous for them. |
| Having bleeding in the brain (Intracranial Hemorrhage) | If there is already bleeding in the brain, performing this type of surgery could make the situation worse. |
| Uncontrolled high blood pressure | The risks are higher when having surgery with very high blood pressure. |
What are the main methods for removing these blood clots?
There are two main ways to perform a thrombectomy. It's like making a big hole to build a road, or drilling a small hole and repairing it from the inside.
1. Open surgery (Surgical / Open Thrombectomy)
In this procedure, the surgeon cuts the skin over the vein containing the blood clot, slowly opens the vein, inserts a special balloon-like device (a `balloon catheter`) and pulls out the blood clot. The vein is then carefully sewn back together and the skin is closed. This is the traditional method.
2. Percutaneous / Minimally Invasive Thrombectomy
This is the most commonly used and advanced method now. There is no large incision. Instead, a small hole is made in a blood vessel in the arm or leg, and a thin tube (catheter) is inserted through it.
Using imaging technology like X-rays, this tube is guided to the location of the blood clot. Then, special instruments are passed through the tube,
- The blood clot can be broken into small pieces and dissolved (`macerated`).
- Alternatively, the blood clot can be sucked out, like with a vacuum cleaner (`Aspiration Thrombectomy`).
This method is very successful because there is no major injury, so the patient can recover quickly.
What conditions can be treated with this treatment?
This treatment, called thrombectomy, is used for many very important medical conditions.
- Deep Vein Thrombosis (DVT): Blood clots, mainly in the deep veins of the legs.
- Stroke: A blood clot blocks a blood vessel that supplies blood to the brain.
- Myocardial Infarction: A blood clot in the coronary arteries that supply blood to the heart.
- Pulmonary Embolism: A blood clot that has formed elsewhere in the body breaks loose and becomes lodged in a vein in the lungs.
- Acute Limb Ischemia: Sudden loss of blood flow to an arm or leg.
- Blockage of the blood vessels supplying blood to the intestines (`Mesenteric Ischemia`) or kidneys (`Renal Artery Occlusion`).
What happens before and after treatment?
Before treatment
Sometimes this is done as an emergency procedure, so there is no time to prepare. However, before a planned thrombectomy, your doctor may ask you to:
- Imaging tests: An ultrasound, MRI, or CT scan may be ordered to determine the exact size and location of the blood clot.
- Quitting smoking: If you smoke, you are advised to quit before surgery.
- Medication Awareness: You should tell your doctor about all medications you are taking (including blood thinners, pain relievers, and vitamins). Some medications may need to be stopped before surgery.
After treatment
After treatment, you will be taken to an observation unit and monitored until your condition stabilizes. Some people can go home the same day. Others may need to stay in the hospital for a few days. This depends on where the blood clot is and the type of treatment given.
After going home,
- Provides advice on how to keep the wound clean.
- You will need to continue taking blood thinners to prevent blood clots from forming again.
- You may be told to wear special socks (compression stockings) for your legs.
The most important thing is to follow your doctor's instructions exactly.
What are the benefits and risks?
Like any medical treatment, this one has both benefits and risks.
| Benefits | Risks |
|---|---|
| Being able to save lives. | Bleeding. |
| Minimizing permanent damage to organs. | Damage to the blood vessel. |
| Reducing disability in a condition such as stroke. | Wound infection. |
| Eliminating the risk of losing an arm or leg. | Reoccurrence of a blood clot. |
| Quickly restore blood circulation. | The clot dislodges and becomes lodged in the lungs (Pulmonary Embolism). |
When to seek immediate medical advice
If you experience any of the following symptoms after your treatment, call your doctor immediately or go to the Emergency Department (ETU) of the nearest hospital.
- Bleeding or pus oozing from the wound.
- Chest pain or difficulty breathing.
- Fever .
- Severe dizziness or lightheadedness.
- Confusion or loss of consciousness.
- Severe pain, swelling , or numbness in the arms or legs.
Don't ignore these symptoms. They could be a sign of another complication.
Take-Home Message
- Thrombectomy is a life-saving treatment that removes a dangerous blood clot stuck in a blood vessel and restores blood flow.
- There are open surgeries as well as advanced catheter-based methods for this.
- It is commonly used for serious conditions such as stroke, heart attack, and DVT.
- It is essential to use the medication prescribed by your doctor exactly as prescribed to prevent blood clots from forming again after treatment.
- Inform your doctor immediately about any unusual symptoms that occur after treatment.
