About Your Hepatic Embolization

This information will help you get ready for your hepatic embolization procedure at Memorial Sloan Kettering (MSK).

A hepatic embolization stops the blood flow to liver tumors. The hepatic artery is the main source of blood for most liver tumors. During your hepatic embolization, your doctor will thread a small catheter (thin flexible tube) in your hepatic artery. Then, they will inject tiny particles in the catheter. These particles will block the blood flow to the tumor, which will kill it.

Your hepatic embolization will be done by an interventional radiologist. An interventional radiologist is a doctor who specializes in image-guided procedures.

Contrast Dye

Contrast is a special dye that makes it easier for your doctor to see differences in your internal organs. The contrast material will be injected into a vein in your arm or hand during your hepatic embolization.

If you’ve had an allergic reaction to contrast in the past, tell your doctor or nurse. You may need to take medication before your procedure to help with the allergy.

If you’re breastfeeding, you may choose to continue after your hepatic embolization. If you have questions or would like to discuss contrast and breastfeeding, talk with your interventional radiologist on the day of your procedure.

Ask about your medications

You may need to stop taking some of your medications before your procedure. Talk with your doctor about which medications are safe for you to stop taking. We have included some common examples below.

Anticoagulants (blood thinners)

If you take a blood thinner (medication that affects the way your blood clots), ask the doctor performing your procedure what to do. Their contact information is listed at the end of this resource. Whether they recommend you stop taking the medication depends on the reason you’re taking it.

Do not stop taking your blood thinner medication without talking with your doctor.

Examples of Blood Thinners
apixaban (Eliquis®) dalteparin (Fragmin®) meloxicam (Mobic®) ticagrelor (Brilinta®)
aspirin dipyridamole (Persantine®) nonsteroidal anti-inflammatory drugs (NSAIDs) such as ibuprofen (Advil®) or naproxen (Aleve®) tinzaparin (Innohep®)
celecoxib (Celebrex®) edoxaban (Savaysa®) pentoxifylline (Trental®) warfarin (Coumadin®)
cilostazol (Pletal®) enoxaparin (Lovenox®) prasugrel (Effient®)  
clopidogrel (Plavix®) Fondaparinux (Arixtra®) rivaroxaban (Xarelto®)  
dabigatran (Pradaxa®) heparin (shot under your skin) sulfasalazine (Azulfidine®, Sulfazine®)  

Please read our resource Common Medications Containing Aspirin and Other Nonsteroidal Anti-inflammatory Drugs (NSAIDs). It has important information about medications you’ll need to avoid before your procedure and what medications you can take instead.

Medications for diabetes

If you take insulin or other medications for diabetes, ask the doctor who prescribes the medication what you should do the morning of your procedure. You may need to change the dose before your procedure.

Diuretics (water pills)

If you take any diuretics (medications that make you urinate more often), ask the doctor performing your procedure what to do. You may need to stop taking them the day of your procedure. Diuretics are sometimes called water pills. Some examples are furosemide (Lasix®) and hydrochlorothiazide.

The Day of Your Procedure

Things to remember

  • Take only the medications your doctor told you to take the morning of your procedure. Take them with a few sips of water.
  • If you’re taking pain medication, take it before your procedure with a few sips of water.
  • Don’t use any cream, petroleum jelly (Vaseline®), powder, makeup, perfume, or cologne. You can use deodorant and light moisturizers.
  • Don’t wear any metal objects. Remove all jewelry, including body piercings.
  • Leave valuables (such as credit cards or jewelry) at home.
  • If you wear contact lenses, wear your glasses instead.

What to bring with you

  • A list of the medications you take at home, including patches and creams.
  • Medications for breathing problems (such as inhalers), medications for chest pain, or both.
  • A case for your glasses or contacts.
  • Your Health Care Proxy form, if you have completed one.
  • If you use a C-Pap or Bi-pap machine to sleep at night, please bring your machine with you, if possible. If you can’t bring your machine with you, we will give you one to use while you’re in the hospital.

Where to go

Your procedure will take place at:

Memorial Hospital (MSK’s main hospital)
1275 York Avenue (between East 67th and East 68th Streets)
New York, NY 10065
Take the M elevator to the 2nd Floor. Enter through the glass doors.

Parking when you arrive

Parking at MSK

MSK’s parking garage is located on East 66th Street between York and First Avenues. If you have questions about prices, call 212- 639-2338.

To reach the garage, turn onto East 66th Street from York Avenue. The garage is located about a quarter of a block in from York Avenue, on the right-hand (north) side of the street. There is a pedestrian tunnel that you can walk through that connects the garage to the hospital.

There are also other garages located on East 69th Street between First and Second Avenues, East 67th Street between York and First Avenues, and East 65th Street between First and Second Avenues.

What to expect

Once you arrive at the hospital, doctors, nurses, and other staff members will ask you to state and spell your name and date of birth many times. This is for your safety. People with the same or similar names may be having procedures on the same day.

After changing into a hospital gown, you will meet your nurse. They will place an intravenous (IV) catheter into one of your veins, usually in your hand or arm. The IV will be used to give you anesthesia (medication to make you sleep) during your procedure.

During your procedure

When it’s time for your procedure, you will be brought into the procedure room. You will be attached to equipment to monitor your heart, breathing, and blood pressure. You will also receive oxygen through a thin tube that rests below your nose.

A member of our clinical team will help position you onto your back. Your groin will be cleaned, shaved, and covered with sterile drapes. A local anesthetic (medication to make you numb) will be injected into the area where your doctor will be working.

Your doctor will thread the catheter through the artery in your groin up to the artery that supplies the blood to your liver. To make sure the catheter is in the right place, they will do an angiogram. An angiogram is an x-ray test that uses contrast dye to allow your doctor to find your tumor and arteries.

Once your tumor is located, your doctor will inject the particles that block the artery. When the procedure is completed, your doctor will remove the catheter and cover site with a dressing.

After Your Procedure

In the hospital

After the procedure, you will be brought to the Post Anesthesia Care Unit (PACU). While you’re in the PACU, tell your nurse if your dressing feels wet or warm.

Your nurse will monitor your site for any bleeding. You will need to lie flat on your back in bed with your leg straight for at least 1 hour. Depending on how the hole was closed, you make need to lie like this for up to 4 hours.

Once your anesthesia has worn off, you will be taken to your hospital room. Most people stay in the hospital for 3 days.

Showering

  • You can shower 24 hours after your procedure. Remove the dressing before you shower. Gently wash the area with soap and water. Pat dry with a clean towel. You may want to place a bandage (Band Aid®) over the area if there is any drainage.
  • Don’t swim, sit in a hot tub, or take a bath for 1 week after your procedure.

Side effects

After your procedure, you may have:

  • A fever of 100.4° F (38 ° C) or higher
  • Pain
  • Nausea (feeling like you’re going to throw up)
  • Vomiting (throwing up)

You will get medication to manage your symptoms, if needed.

When to Call Your Doctor or Nurse

Call your doctor or nurse if you have:

  • A fever of 100.4° F (38° C) or higher
  • Pain, nausea, or vomiting that is uncontrolled or worse than it was before your procedure
  • Redness, swelling, or bleeding around the procedure site
  • Any symptoms that are worrying you
