Endovascular embolization is a procedure to treat abnormal blood vessels in the brain and other parts of the body. It is an alternative to open surgery. This procedure cuts off the blood supply to a certain part of the body.
Full Answer
How is embolization with chemotherapy (chemo) done?
It combines embolization with chemotherapy (chemo). Most often, this is done by giving chemotherapy through the catheter directly into the artery, then plugging up the artery, so the chemo can stay close to the tumor.
What follow-up is required after embolization for the treatment of embolism?
Most patients treated by embolization will also need to return for a follow-up angiogram or magnetic resonance angiogram (MRA), usually performed several months after the treatment to confirm that the outcome of the treatment is stable in time.
What is radioembolization used to treat?
Radioembolization. This technique combines embolization with radiation therapy and is sometimes known as trans-arterial radioembolization. In the United States, this is done by injecting small beads (called microspheres) that have a radioactive isotope (yttrium-90) stuck to them into the hepatic artery.
Can embolization be used with ablation?
It can also be used with ablation. Embolization can reduce some of the blood supply to the normal liver tissue, so it may not be a good option for some patients whose liver has been damaged by diseases such as hepatitis or cirrhosis. It isn’t yet clear which type of embolization has a better long-term outcome.
How serious is an embolization?
Serious complication rates vary between 0 and 6% when looking at large series. Generally considered minor, the most common complication encountered is headache or temporofacial pain, more common in cases where two or more arteries are embolized with gelatin sponge.

Listen to pronunciation. (tranz-ar-TEER-ee-ul EM-boh-lih-ZAY-shun) A procedure in which the blood supply to a tumor or an abnormal area of tissue is blocked.
Why do you need a stent for an aneurysm?
A stent may cover the neck of the aneurysm allowing for safe deposition of coils in the aneurysm without any coil mass protruding into the parent artery. 1. When the neck of the aneurysm is too wide, a stent is sometimes necessary to be placed in the parent vessel to hold the coils inside the body of the aneurysm. 2.
How is a platinum catheter released?
When in position, the coil is released by an application of a very low voltage current causing the coil to detach from the pusher wire.

Some doctors will use one groin site to treat both the left and right uterine arteries if needed. Other doctors may use two groin sites. The sheath and catheter will be removed after the embolization is done.
How does uterine fibroid embolization shrink fibroids?
Uterine fibroid embolization shrinks fibroids by blocking off their blood supply. The doctor injects very small particles like sand into the arteries that supply the fibroids. The particles stick to the vessel wall. This causes a clot to develop that blocks off the blood supply. Once the blood supply is gone, the fibroids shrink.
Why do women have fibroid embolization?
The main reason to have a uterine fibroid embolization is to treat uterine fibroid tumors that are causing pain or other problems. Nearly all fibroid tumors are benign or not cancerous.

Overview
A majority of men over the age of 50 have one thing in common: an enlarged prostate. About half of men between 51 and 60 develop the condition, and that number steadily climbs in the decades that follow.
What is prostate artery embolization (PAE)?
Prostate artery embolization (PAE) is an outpatient procedure performed by an interventional radiologist that involves the release of microscopic, plastic beads into the arteries that feed the prostate gland.
What is prostate artery embolization used for?
PAE is for men who have enlarged prostates. While not life-threatening, an enlarged prostate can negatively impact a man’s day-to-day life. Men with this condition can encounter sexual and urinary issues. Urine flow can become very slow and frequent.
What happens during the PAE procedure?
It works by placing a tiny catheter into the arteries that feed the prostate gland. A solution containing thousands of microscopic plastic beads is injected; these block the blood supply by shutting down blood flow to the gland. All of this is accomplished through a tiny quarter-inch hole in the skin.
How long does the procedure take?
The outpatient procedure takes about two hours, so patients go home the same day. Recovery typically takes just a few days at home before patients can return to work and other routine activities.
Who is a candidate for PAE?
All men who’ve been diagnosed with BPH, who experience symptoms that are not controlled well by medications and who are not able to or do not want to undergo invasive surgical treatments, are candidates for PAE. Patients must have reasonable kidney function and not be allergic to the contrast dye used during the procedure.
What are the risks involved with PAE?
PAE has been shown to have fewer side effects than other widely used treatments for BPH such as transurethral resection of the prostate (TURP) surgery, which is associated with incontinence, impotence, retrograde ejaculation and erectile dysfunction issues in men.
Trans-Arterial Embolization
Trans-Arterial Chemoembolization
- Trans-arterial chemoembolization is usually the first type of embolization used for large liver cancers that cannot be treated with surgery or ablation. It combines embolization with chemotherapy (chemo). Most often, this is done by giving chemotherapy through the catheter directly into the artery, then plugging up the artery, so the chemo can stay close to the tumor.
Drug-Eluting Bead Chemoembolization
- Drug-eluting bead chemoembolization combines TACE embolization with drug-eluting beads (tiny beads that contain a chemotherapy drug). The procedure is essentially the same as TACE except that the artery is blocked after drug-eluting beads are injected. Because the chemo is physically close to the cancer and because the drug-eluting beads slowly release the chemo, the cancer cel…
Radioembolization
- Radioembolization combines embolization with radiation therapy. This is done by injecting small beads (called microspheres) that have a radioactive isotope (yttrium-90 or Y-90) attached to them into the hepatic artery. Once infused, the beads lodge in the blood vessels near the tumor, where they give off small amounts of radiation to the tumor site...
Possible Side Effects of Embolization
- Possible complications after embolization include: 1. Abdominal pain 2. Fever 3. Nausea 4. Infection in the liver 5. Blood clots in the main blood vessels of the liver Sometimes, it can take 4-6 weeks to fully recover from the procedure. Because healthy liver tissue can be affected, there is a risk that liver function will get worse after embolization. This risk is higher if a large branch of th…
