Welcome
to the Information Resource Page for the division of Neuroradiology at
Fletcher Allen Health Care in Burlington Vermont.
Disclaimer: This page is for general information purposes only. Each patient
is different and choice of procedure, risks, and benefits will vary among
individuals depending on underlying medical conditions. Please contact
your physician for specific questions and advice.
Statement
of Purpose:
- Our
intent is to: Provide patients with access to information about Neuroradiology
in general.
- Enable
patients to access this information from an environment less intimidating
than the hospital or physician’s office, (i.e. home, workplace or local
library.)
-
Better prepare patients for specific interventional procedures prior
to the scheduled date.
Below
are some facts regarding a number of procedures we perform in our department.
Cerebral
Angiogram
What Is It?
A cerebral angiogram is a test to look at the blood vessels in your brain.
This is done by injecting contrast dye through a small tube (catheter)
into one of your arteries and then taking x-ray pictures. The test often
lasts 1-2 hours. The potential complications of this procedure include
but are not limited to seizure, stroke, infection or bleeding.
What
Should I Do To Get Ready?
Please
let us know if you have any allergies, especially to iodine or shellfish.
The morning of the test you should not have anything to eat or drink.
Clear liquids should be stopped at the time you are to report to registration.
You may take your oral medications with sips of water unless your doctor
or nurse has told you otherwise. Please inform your doctor if you are
taking any oral diabetic medications (i.e. Glucophage).
Before
You
will register at the Main Medical Center Campus on Colchester Avenue.
You will be directed to the Radiology Department located on McClure 1.
You will give your name to the Radiology Secretaries and be directed to
the radiology waiting room. You will be greeted by the Angiography Nurse
and be escorted to the pre-procedure area. You will be asked to change
into a hospital gown. An IV will be started in your arm to provide fluids
and a Neuroradiologist or Nurse Practitioner will go over details of the
angiogram with you and answer any questions you may have. In the x-ray
room you will lie on a moveable table and be covered with sterile sheets.
The groin area, just above your leg, at the inner thigh, will first be
shaved and cleansed with a liquid. Then an anesthetic will be injected
to numb that site before the catheter is placed.
During
During
the test, you will need to lie very still to achieve the best results.
Medication may be given through the IV to ensure comfort and relaxation.
As the catheter is guided through your vessels, the pathway will be checked
by x-rays. Once it is in place, there will be several injections of dye.
You will have a warm feeling on the side of neck and face, lasting 30-60
seconds. The doctors and staff step out of the room for a short time while
the x-rays are being taken. At any time during the test, if you feel uncomfortable
or short of breath, tell your doctor.
After
Once
the angiogram is done, the catheter will be removed and firm pressure
or a closure device may used on that area for about 15 minutes to prevent
bleeding. You will then be taken to Baird 3 where you will stay for the
next 6 hours. During that time, you will need to keep your leg straight.
You may roll side to side. A nurse will check your blood pressure, pulse
and the site where the catheter was. You will also be asked to drink plenty
of fluids to help flush the dye from your system. At the end of that time,
when you feel able, and after you have been walking with help, you can
be discharged to home. Keep in mind you must have someone here to drive
you home.
At
Home
Drink
10-20 glasses of fluid the first 24 hours after the procedure. If unresolved
bleeding occurs at the catheter site, apply direct pressure and be driven
to the nearest ER. You should not drink any alcohol during this time.
When
To Call The Doctor?
-
If puncture site becomes red and/or hot
- If
any yellow or green drainage from the site
- If
swelling occurs at the site
- If
your temperature goes above 100 degrees Fahrenheit
- If
a large bruise appears under or around the site
- If
you have severe pain or spasm in the leg
- If
numbness or tingling occurs in foot or leg
- If
itching, hives or rash appear
Phone
Numbers
For
follow-up help, call the hospital paging operator (802) 847-2700. Ask
to speak to the neuroradiologist on call. Give the operator your name
and phone number with area code. The doctor will call you back.

Aneurysm
Coiling
What
Is It?
An
aneurysm coiling is performed in the angiography suite with a catheter
similar to that used during your angiogram/arteriogram. Through the catheter,
the aneurysm is packed with material that does not allow arterial blood
to flow into it. This technique is called embolization. The materials
used for the aneurysm embolization include platinum coils.
Who
Will Perform This Procedure?
Interventional
Neuroradiologists (INR) perform these types of procedures. These physicians
have completed specialized training using x-rays to guide catheters within
the blood vessels. These INRs embrace the treatment of neurological diseases
with neuroendovascular techniques. This includes the delivery of balloons,
particles, coils, and stents within the blood vessels that nourish the
brain.
Will
I Get Medication to Relax During The Procedure?
The
INR is placing very small catheters to the site of the aneurysm, which
requires a patient to be absolutely still; therefore general anesthesia
is preferred.
How
Do I Know This Procedure Is Suitable For Me?
The
team of physicians, Interventional Neuroradiologists, Vascular Neurologists,
Vascular Neurosurgeons, work together to make the most accurate diagnosis
and care plan based on your disease. If they believe your aneurysm may
be treated using an endovascular technique our office will be contacted.
Subsequently, our Clinical Office Assistant (COA) will contact you for
an initial consultation with INR and the Nurse Practitioner (NP).
What
Should I Expect The Day Of The Consultation?
The
day of your consultation you will register at the Main Medical Center
on Colchester Avenue. You will be directed to the Radiology Department
on the first floor located on McClure 1. You will give your name to the
Radiology Secretaries and be directed to the radiology waiting room. You
will be greeted by the NP and be escorted to the Invasive Procedure Clinic
(IPC) where the consultation will take place. An explanation of the procedure,
the risks and benefits identified, a medical history will be collected
and a physical examination will be completed. This consultation also provides
you with the opportunity to ask the INR any questions you may have. The
results of the consultation will be discussed with your referring provider.
If
I Decide To Have This Aneurysm Coiling Procedure, What Should I Do To
Get Ready?
Before
The
IPC staff will make the necessary arrangements for you to be prepared
the day of your procedure. You will need a complete history and physical
within 30 days of your procedure and blood studies within 14 days. An
electrocardiogram and/or x-ray of your chest may be required for your
procedure.
The
NP will discuss your individual plan with you and will make the necessary
arrangements for the requirements to be completed and reviewed prior to
the procedure.
After
these studies are completed, the anesthesiologist will need to review
your medical history with you. This may be completed by an on-site visit
or by telephone. This individual will instruct you when to stop eating
and drinking, discuss medication matters, and notify you as to what time
to report to registration.
Day
Of The Procedure
You
will register at the Main Medical Center Campus on Colchester Avenue.
You will be directed to the Radiology Department on McClure 1. The secretaries
will direct you to the radiology waiting room. The preprocedure nurse
will take you to designated pre-operative area where you will be asked
to change into a hospital gown. At this time your family/friends will
be directed to the Surgical Waiting Area. An IV will be started in your
arm to provide fluids. The INR may obtain your consent for the procedure
at this time if it had not been done prior. This also applies to the Anesthesiologist’s
obtaining consent for the anesthesia.
You
will be taken to the angiography suite for the procedure. Once you arrive
to the suite a small tube will be placed in your bladder and your groin
area, just above your leg, at the inner thigh, will be shaved and cleansed
with a liquid. As the procedure begins, the anesthesiologist will give
you medication to ensure your comfort and relaxation. Your procedure will
take several hours. Your family/friends will be notified of the completion.
After
After
the procedure is completed, you will be taken to the Post Anesthesia Care
Unit (PACU) for several hours and then to the Intensive Care Unit (ICU),
lying flat on your back for up to six hours. This rest period allows the
artery in your groin to heal. You will be admitted to the Neurosurgery
or Neurological service for close observation for a day or two. The number
of days will vary depending on your condition. During your hospital stay,
Neurologists, Neurosurgeons, and Interventional Neuroradiologists and
other medical staff may see you. Prior to your discharge, you will be
given written instructions regarding your activity level, diet, medications
and follow- up appointments. The INR will expect to see you one to two
weeks following the procedure. This may be arranged prior to your discharge.
What Can I Expect After The Procedure?
In
collaboration with the referring physician, the INR may recommend particular
medications or studies to be done in the weeks or months to follow. The
INR will discuss your plan of care with you at your follow- up clinic
visit.

Embolization
of Arteriovenous Malformation
What
Is It?
An
arteriovenous malformation (AVM) is a tangle of abnormally connecting
arteries and veins. An embolization of an AVM involves the blocking off
the blood supply that flows through the malformation. This is performed
in the angiography suite with a catheter similar to that used during your
angiogram/arteriogram. Through the catheter, the malformation is occluded
with material that does not allow blood to flow into it. This technique
is an embolization. The materials used for the malformation embolization
include coils, glue and/or synthetic particles (embospheres). This procedure
can be done in conjunction with other therapies, for example radiosurgery.

Carotid
Stent Placement
What Is It?
The
placement of a carotid stent is performed in the angiography suite with
a catheter similar to that used during your angiogram/arteriogram. A small
tube is threaded up from the groin and once in the carotid artery, a small
metal pipe or stent, is positioned at the site of the narrowing. This
stent is expanded and opens up the narrowing in the carotid artery to
allow arterial blood to flow through it.
Who
Will Perform This Procedure?
Interventional
Neuroradiologists (INR) perform these types of procedures. These physicians
have completed specialized training using x-rays to guide catheters within
the blood vessels of the central nervous system. These INRs embrace the
treatment of neurological diseases with neuroendovascular techniques.
This includes the delivery of balloons, particles, coils, and stents within
the blood vessels that nourish the brain. This stent is not yet an FDA
approved use but it is widely used in various cases, such as patients
with high bifurcation stenosis (narrowing) or those with carotid stenosis
as a result of radiation therapy.
Will I Get Medication to Relax During The Procedure?
The
INR is placing very small catheters to the site of the narrowing, which
requires a patient to be absolutely still; therefore general anesthesia
is preferred.
How
Do I Know This Procedure Is Suitable For Me?
The
team of physicians, Interventional Neuroradiologists, Vascular Neurologists,
Vascular Neurosurgeons, work together to make the most accurate diagnosis
and care plan based on your disease. There are certain features of stenosis
(narrowing), for example the size of the artery or the location of the
blockage, or certain medical conditions in your history that may necessitate
this approach.
If
they believe your carotid artery stenosis may be treated using an endovascular
technique our office will be contacted. Subsequently, our Clinical Office
Assistant (COA) will contact you for an initial consultation with INR
and the Nurse Practitioner (NP).

Vertebroplasty
What
Is It?
A vertebroplasty
procedure is a treatment for fractures of the vertebrae. The most common
condition causing these fractures is osteoporosis. This is a condition
in which the bones become thin and fragile. A simple twist or strain can
result in a bone fracture in a patient with osteoporosis. Vertebroplasty
is a potential treatment for these fractures. This procedure is performed
in the angiography suite, allowing the physician to use x-ray while inserting
needles through the skin and into the fractured (“crushed”)
vertebrae. A cement is injected into the bone to stabilize the vertebrae.
Who
Will Perform This Procedure?
Interventional
Neuroradiologists (INR) perform these types of procedures. These physicians
have completed specialized training using x-rays to perform minimally
invasive procedures, such as vertebroplasty.
Will
I Get Medication to Relax During The Procedure?
The
INR is placing needles into the vertebrae, which requires a patient to
be still; therefore conscious sedation is administered through an IV by
the radiology nursing staff. This medication is to ensure comfort and
relaxation. The INR will also use local numbing medicine at the insertion
site. It is critical you report any allergies.
How
Do I Know This Procedure Is Suitable For Me?
The
team of physicians, Interventional Neuroradiologists, the Spine Specialists
and your referring provider work together to make the most accurate diagnosis
and care plan based on your disease. If they believe your spinal fracture
may be treated with vertebroplasty our office will be contacted. Subsequently,
our Clinical Office Assistant (COA) will contact you for an initial consultation
with INR and the Nurse Practitioner (NP). It is possible, our team will
arrange for further imaging of the spine. There are certain studies required,
for example a CT scan or MRI, to proceed with the consideration for this
particular procedure. This is decided on an individual basis.
What
Should I Expect The Day Of The Consultation?
The
day of your consultation you will register at the Main Medical Center
on Colchester Avenue. You will be directed to the Radiology Department
on the first floor located on McClure 1. You will give your name to the
Radiology Secretaries and be directed to the radiology waiting room. You
will be greeted by the NP and be escorted to the Invasive Procedure Clinic
(IPC) where the consultation will take place. An explanation of the procedure,
the risks and benefits identified, a medical history will be collected
and a physical examination will be completed. This consultation also provides
you with the opportunity to ask the INR any questions you may have. The
results of the consultation will be discussed with your referring provider.
If
It Is Decided I Am An Appropriate Candidate For A Vertebroplasty, What
Should I Do To Get Ready?
Before
The
IPC staff will make the necessary arrangements for you to be prepared
the day of your procedure. You will need blood studies within 14 days.
The NP will discuss your individual plan with you and will make the necessary
arrangements for the requirements to be completed and reviewed prior to
the procedure.
The
pre-procedure nurse will contact you the day before the scheduled procedure.
She will instruct you when to stop eating and drinking, discuss medication
matters, and notify you as to what time to report to registration.
Day
Of The Procedure
You
will register at the Main Medical Center Campus on Colchester Avenue.
You will be directed to the Radiology Department on McClure 1. The secretaries
will direct you to the radiology waiting area. You will be greeted by
the pre-procedure nurse and escorted to the pre-procedure holding area
where you will be asked to change into a hospital gown. An IV will be
started in your arm to provide fluids. The INR or NP will obtain your
consent for the procedure and for the sedation.
You
will be taken to the angiography suite for the procedure. Once you arrive
to the suite your back will be cleansed with a liquid by the technologist.
As the procedure begins, the radiology nurse will give you the sedative.
Your procedure will take approximately 1 ½ hours. Your family/friends
will be notified of the completion.
After
After
the procedure is completed, you will be taken to the recovery floor on
Baird 3. You will required to lie flat for 2 hours after the procedure.
This will ensure the cement has ample time to dry properly. The recovery
nurses will monitor your vital signs, the wound and your activity tolerance.
You will be asked to walk in the hallway prior to your discharge. You
are required to have someone available to drive you home. Prior to your
discharge, you will be given written instructions regarding your activity
level, diet, medications and follow- up appointments. The INR will expect
to see you one week following the procedure or arrangements will be made
for a follow-up telephone call. This may be arranged prior to your discharge.
What Can I Expect After The Procedure?
There
are individuals who feel immediate relief of their symptoms following
the procedures others report improvement within 48 hours. Many people
can resume normal activities within days, however people often will OVERDUE
it because they feel well. Our recommendations are to gradually increase
your activity level. Remember a simple movement is likely what caused
the initial fracture. Vertebroplasty is a treatment for that fracture
not for the underlying osteoporosis.
