This information will help you get ready for your portal vein embolization at Memorial Sloan Kettering (MSK).
About Your Portal Vein
Your portal vein is a vein that carries blood from your stomach and intestines to your liver. It then splits into the left and right portal veins. These branch into smaller vessels that deliver blood throughout your liver (see Figure 1).Back to top
About Your Portal Vein Embolization
An embolization is a procedure that blocks the flow of blood to an area. A portal vein embolization blocks blood flow to the sections of your liver using tiny particles. The tiny particles are placed into your vein through a needle and catheter (small, flexible tube) (see Figure 2).
When the blood flow is blocked, the sections of your liver with the tumor will get smaller. At the same time, the other sections of your liver will get bigger. This is because more blood is flowing to the unblocked side.
About 3 to 4 weeks after your portal vein embolization you will have liver resection surgery to remove the part of your liver that has cancer. The enlarged side of your liver will make it easier for your doctor to remove the other side of it.
Before Your Procedure
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 here.
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.
Contrast is a special dye that makes it easier for your doctor to see your internal organs. The contrast dye will be injected into your portal vein during your procedure.
If you’ve had a reaction to contrast in the past, tell your doctor or nurse.
You must have someone 18 years or older take you home after your procedure. If you don’t have someone to do this, call one of the agencies below. They will send someone to go home with you. There’s usually a charge for this service, and you will need to provide transportation.

During Your Procedure
Your doctor will help you onto the exam table where you will lie on your back.
Your doctor will numb the area. They will insert a needle into the skin by your liver, in the upper right part of your abdomen. Using real-time x-rays (fluoroscopy) and contrast dye, your doctor will place the needle into your portal vein and insert a catheter into it. Once the catheter is where your doctor wants it to be, the particles will be injected.
The catheter will be removed and a small bandage will be placed on the site.
Your procedure will take about 2 to 3 hours.Back to top
After Your Procedure
After your procedure, your doctor will bring you to the recovery room. You may have bleeding, but this is rare.
While you’re in the hospital, let your doctor or nurse know if you have pain. They will give you medication.
If you’re going home the same day, your nurse will remove your IV. They will also explain your discharge instructions to both you and your caregiver before you go home.
If you’re staying in the hospital overnight, you will be transferred to a hospital room. Most people are discharged the day after their procedure.Back to top
- You will have a computed tomography (CT) scan 3 to 4 weeks after your procedure. It will help your surgeon see how your liver has changed. The part of your liver that had the portal vein blocked should be smaller. The other part should be bigger.
- Your liver resection surgery will be scheduled around this time.
Call Your Doctor Or Nurse If You Have:
- A temperature of 100.4° F (38.0° C) or higher.
- Pain that is worse, new, or doesn’t get better with medication.
