Surgical Thrombectomy

What is surgical thrombectomy?

Surgical thrombectomy is a type of surgery to remove a blood clot from inside an artery or vein.

Normally, blood flows freely through your blood vessels, arteries, and veins. Your arteries carry blood with oxygen and nutrients to your body. Yours veins carry waste products back to the heart. In some cases, an abnormal blood clot can form in one of these vessels. This can block the blood flow. When blood flow is blocked, nearby tissues can be damaged.

During a surgical thrombectomy, a surgeon makes an incision into a blood vessel. The clot is removed, and the blood vessel is repaired. This restores blood flow. In some cases, a balloon or other device may be put in the blood vessel to help keep it open.

Why might I need surgical thrombectomy?

You might need surgical thrombectomy if you have a blood clot in an artery or vein. This surgery is often needed for a blood clot in an arm or leg. In some cases, it may also be needed for a blood clot in an organ or other part of the body.

A blood clot can lead to many possible problems, such as:

  • Swelling, pain, numbness, or tingling in an arm or leg
  • A cold feeling in the area
  • Muscle pain in the area
  • Enlarged veins (postthrombotic syndrome)
  • Death of tissue
  • Loss of function of an organ
  • Blood clot moving to the lung that causes breathing trouble and risk of death (pulmonary embolism)

Your doctor might advise surgical thrombectomy if you have a very large clot. Or, he or she may advise surgery if your blood clot is causing severe tissue injury. Surgery is not the only kind of treatment for a blood clot. Many people with blood clots are treated with medications called blood thinners. These are given as an injection or through an IV. They can prevent a blood clot from getting larger.

All treatments for blood clots have their own risks and benefits. Ask your doctor if surgical thrombectomy might be a good choice for you. You might find it helpful to talk to a doctor who specializes in blood vessel problems. This type of doctor is called a vascular specialist.

What are the risks of surgical thrombectomy?

All surgery has risks. The risks of surgical thrombectomy include:

  • Excess bleeding that can be severe enough to cause death
  • Infection
  • Damage to the blood vessel at the site of the blood clot
  • Reaction to anesthesia
  • Postthrombotic syndrome
  • Pulmonary embolism

There is also a risk that your blood clot will form again. Your own risks may vary depending on your general health and how your blood clots. They may also vary depending on how long you’ve had the clot, and where it is in your body. Talk with your doctor about all your concerns and questions.

How do I prepare for a surgical thrombectomy?

Talk with your doctor how to prepare for your surgery. Tell your doctor about all the medications you take. This includes over-the-counter medications such as aspirin. You may need to stop taking some medications ahead of time, such as blood thinners. If you smoke, you’ll need to stop before your surgery. Smoking can delay healing. Talk with your doctor if you need help to stop smoking.

You may need some tests before the procedure, such as:

  • Ultrasound, to measure blood flow in the leg and help diagnose the blood clot
  • Venogram (for a vein clot) or arteriogram (for an artery clot), to get an image of your vessels
  • Computed tomography (CT) scan, to get more information about the blood clot
  • Magnetic resonance imaging (MRI), if more information is needed
  • Blood tests, to check your overall health

Do not eat or drink after midnight the night before your surgery. Tell your doctor about any recent changes in your health, such as a fever.

What happens during a surgical thrombectomy?

Talk with your doctor about what to expect during the surgery. The details will vary depending on the type of your surgery. They will also vary depending on what part of the body is treated. A typical surgical thrombectomy may go like this:

  • An IV will be put in your arm or hand before the procedure starts. You’ll receive medications through this IV. You may be given a blood thinner such as heparin. This is to help prevent new blood clots forming during the surgery.
  • You’ll also be given anesthesia through the IV line. This will prevent pain and make you sleep during the surgery. Or, you may be given sedation. This will make you relaxed and sleepy during surgery.
  • Hair in the area of your surgery may be removed. The area may be numbed with a local anesthesia.
  • The surgeon may use continuous X-ray images while the surgery is being done.
  • The doctor will make a cut in the area above your blood clot. He or she will open the blood vessel and take out the clot.
  • In some cases, a balloon attached to a thin tube (catheter) will be used in the blood vessel to remove any part of the clot that remains. A stent may be put in the blood vessel to help keep it open.
  • Your doctor will close and repair the blood vessel. This will then restore blood flow.
  • The incision on your skin will be closed and bandaged.

What happens after a surgical thrombectomy?

After the procedure, you will spend several hours in a recovery room. Your healthcare team will watch your vital signs, such as your heart rate and breathing. You may need to stay at the hospital for a day or more, depending on your condition. Your doctor will tell you more about what to expect.

After the procedure, you may need to take medications for a short time to help prevent blood clots. Your doctor will let you know about any other changes in your medications. You can take pain medication if you need it. Ask your doctor which to take.

Your healthcare provider will likely advise you to get back on your feet soon after the treatment. You may need to wear compression stockings. This is to help prevent the clot from forming again. It can also help prevent a new one from forming.

You should stop smoking. This will lower your risks of blood clots forming in the future. Talk with your doctor if you need help to quit smoking.

Your doctor will keep track of your health after you go home. You’ll have follow-up appointments. Your doctor may check on your blood vessels with an imaging test called a venogram. Make sure to keep all of your follow-up appointments. This will help your doctor can keep track of your progress.

Call your healthcare provider right away if you have any of the following:

  • Swelling or pain that gets worse
  • Fluid leaking from the incision
  • Fever
  • Bleeding anywhere on your body
  • Weakness, pain, or numbness in the surgery area

Follow all of your doctor’s instructions. This includes any advice about medications, exercise, and wound care.
