Background Information:

What are the other Names for the Procedure?

  • Brain Aneurysm Vascular Embolization

What is Embolization of Brain Aneurysm radiology procedure? (General Explanation)

  • An embolization is a minimally invasive procedure used to treat aneurysms and other blood vessel abnormalities in the brain
  • Due to blood vessel wall weakness, the artery develops a bulge called an aneurysm. This aneurysm compresses surrounding the vessels resulting in nerve paralysis, upper back pain, nausea, vomiting, and headache. A stroke or even death may occur, if the aneurysm in the brain ruptures
  • The Embolization of Brain Aneurysm procedure involves placing soft metal coils within the aneurysm to stop a potential rupture

What part of the Body does the Procedure involve?

The Embolization of Brain Aneurysm procedure generally involves the brain and neck region.

Why is the Procedure Embolization of Brain Aneurysm radiology procedure Performed?

  • The Embolization of Brain Aneurysm procedure is performed to treat aneurysms in the brain
  • This procedure can also be used for either ruptured or unruptured aneurysms

What is the Equipment used? (Description of Equipment)

The following equipment is used for the Embolization of Brain Aneurysm procedure:

  • A catheter
  • Detachable coils (bare platinum coils, biologically active coils, or coated platinum coils)
  • Heart rate monitor
  • Blood monitor

What are the Recent Advances in the Procedure?

There have been no recent advances to replace the Embolization of Brain Aneurysm procedure.

What is the Cost of performing the Embolization of Brain Aneurysm radiology procedure?

The cost of the Embolization of Brain Aneurysm procedure depends on a variety of factors, such as the type of your health insurance, annual deductibles, co-pay requirements, out-of-network and in-network of your healthcare providers and healthcare facilities.

Prior to Embolization of Brain Aneurysm radiology procedure:

How does the Embolization of Brain Aneurysm radiology procedure work?

  • A catheter is inserted into the artery using an imaging technique and sent to the site of the aneurysm
  • Coils are inserted through the catheter and placed within the aneurysm. The body starts healing around the coil and blood flow into the aneurysm is blocked, thus preventing its rupture

How is the Embolization of Brain Aneurysm radiology procedure Performed?

The Embolization of Brain Aneurysm procedure is performed in the following manner:

  • A CT scan or MRI is performed before the embolization procedure
  • The patient’s heart rate, blood pressure, and pulse are monitored
  • An intravenous (IV) line is inserted into the patient’s arm and sedatives are given through IV lines
  • A catheter is inserted and sent to the site of the aneurysm
  • Once the catheter is on the target site, detachable coils are inserted and placed in the aneurysm
  • The catheter and IV lines are removed at the end of the procedure
  • If the aneurysm has ruptured, the patient may have to stay in the hospital for a few days

Where is the Procedure Performed?

The Embolization of Brain Aneurysm procedure is performed as an outpatient procedure, at a hospital.

Who Performs the Procedure?

An Embolization of Brain Aneurysm is performed by interventional radiologists and interventional neuroradiologists.

How long will the Procedure take?

The Embolization of Brain Aneurysm procedure could take anywhere between 1-3 hours.

Who interprets the Result?

An interventional neuroradiologists interprets the results and informs the primary care physician to set up a follow-up care for the patient.

What Preparations are needed, prior to the Procedure?

The following preparations may be needed prior to an Embolization of Brain Aneurysm procedure:

  • The physician may evaluate the individual’s medical history to gain a comprehensive knowledge of the overall health status of the patient, including information related to the medications that are being currently taken
  • Do inform the medical professional if you have a history of any medical conditions, such as a heart disease, asthma, diabetes, or kidney disease
  • Do inform the medical professional about any allergies, especially related to barium or iodinated contrast material, which may be used in the procedure
  • It is advisable to wear comfortable and loose clothes. Avoid wearing any metal objects or jewelry, as it may interfere with the x-ray
  • Women should notify the physician, if they are pregnant or breastfeeding their child; as many such procedures may not be performed on pregnant women
  • The patient may be asked to avoid eating or drinking, several hours before the test
  • The patient may be asked not to take any blood thinners, such as aspirin, NSAIDs, before the procedure
  • The physician may recommend blood tests before the procedure to check liver and kidney function

What is the Consent Process before the Procedure?

A physician will request your consent for Embolization of Brain Aneurysm using an Informed Consent Form.

Consent for the Procedure: A “consent” is your approval to undergo a procedure. A consent form is signed after the risks and benefits of the procedure, and alternative treatment options, are discussed. This process is called informed consent.

You must sign the forms only after you are totally satisfied with the answers to your questions. In case of minors and individuals unable to personally give their consent, the individual’s legal guardian or next of kin, shall give their consent for the procedure.

What are the Benefits versus Risks, for this Procedure?

Following are the benefits of the Embolization of Brain Aneurysm procedure:

  • Embolization is a minimally-invasive procedure
  • The procedure requires less recovery time than an open surgery
  • There is no requirement for a large surgical incision; a small incision is sufficient enough to access the blood vessels, made either in the arm or leg
  • An embolization procedure is very effective in prolonging life and relieving symptoms that results from an aneurysm

Following are the risks of the Embolization of Brain Aneurysm procedure:

  • There is a slight chance of damaging blood vessels while using a catheter during the procedure
  • The skin is penetrated during the procedure and thus there is some risk of an infection
  • There is a slight chance of illness or death, but very few cases require additional treatments or surgery

What are the Limitations of the Embolization of Brain Aneurysm radiology procedure?

Following are the limitations of the Embolization of Brain Aneurysm procedure:

  • Recurrence of the condition after the procedure: The recurrence depends upon the size and shape of the aneurysm. Small aneurysms with small necks have very low chances of recurrence compared to larger aneurysms with wider necks
  • Balloon stenting or microstenting may be used in the procedure to improve the success rate of the procedure
  • Follow-up checks are required to monitor the condition

What are some Questions for your Physician?

Some of the basic questions that you might ask your healthcare provider or physician are as follows:
