WHAT IS ARTERIAL STENTING?
Arterial stenting is a minimally
invasive procedure used to improve
blood flow when an artery is
narrowed. This helps to restore
healthy blood flow. The stent is
a wire mesh tube that is
permanently placed in a newly
opened artery to help keep it open.
WHAT ARE THE RISKS
OF ARTERIAL STENTING?
• Bleeding, swelling caused by a
collection of blood (hematoma),
injury to nerves, or infection.
• Damage to an artery or an artery
wall. This can cause blood clots,
abnormal ballooning of the artery,
or abnormal link between the
artery and nearby vein.
• Temporary kidney failure. Please
notify your provider if you have
had recent imaging testing that
included contrast, as this would
increase your risk for kidney issues.
TELL YOUR HEALTHCARE
PROVIDER IF YOU:
• Are pregnant or think you may be
pregnant. Radiation exposure
during pregnancy may lead to
birth defects.
• Are allergic to or sensitive to
any medications, contrast, latex,
tape, or anesthetic medicines
(local or general).
• Have kidney failure or other
kidney problems. In some cases,
the contrast can cause kidney
failure. You are at higher risk for
this if you take certain diabetes
medicines. You may need to hold
certain medications prior to the
procedure.
• Are taking any medication that
include prescriptions, over-the-
counter, and herbal supplements.
• Have a bleeding disorder or take
blood thinners, aspirin, or
medications or supplements that
affect blood clotting. These may
have to be stopped prior to the
procedure.
HOW DO I GET READY
FOR ARTERIAL STENTING?
• You will need to have blood work
prior to your procedure. You should
receive an order from your
physician.
• You will be asked not to eat after
midnight prior to the procedure.
You may have clear liquids 2 hours
before your arrival time.
• Bring your insurance card and
picture ID with you to the
appointment. You may bring an
adult guest with you.
• You will need a driver to your
appointment. If you need
transportation, please let the
office know so that we can
arrange it for you.
WHAT HAPPENS PRIOR
TO ARTERIAL STENTING?
• You will read and sign your
consent that gives your
permission for the procedure to be
performed. You will have the
opportunity to ask your provider
questions and have anything
explained that you do not
understand.
• You will be asked to remove any
clothing or jewelry that may get
in the way of the test. You will
be given a gown to wear. You
will be asked to empty your
bladder prior to the test.
• An intravenous (IV) line will
be started in your hand or arm.
You will be connected to a
monitor that records your heart
rate, blood pressure, and breathing.
• You may get medication to
help you relax before the procedure.
WHAT HAPPENS
DURING ARTERIAL STENTING?
Intravascular ultrasound (IVUS)
imaging is used to determine the
size of the vessel and the length
of the stent needed. Then, using
image guidance, the balloon
catheter is advanced through
the artery to the site of the
blockage or narrowing. The
balloon is then inflated to
deploy the stent in the specific
site. The balloon is then
deflated and removed.
WHAT HAPPENS AFTER
ARTERIAL STENTING?
• You will be taken to the
recovery room. A nurse will
watch your vital signs and the
access site(s). They will check the
circulation and sensation in your
extremities.
• Depending on the closure device
used, you will be discharged after
a period of rest and no signs of
bleeding.
• You will be encouraged to drink
water and fluids to help flush the
contrast from your body.
• You will receive written discharge
instructions about returning to
your daily activities and how to
care for your bandage and
incision site.
AT HOME
• Once home, you should watch
the injection site for bleeding. A
small bruise is normal. So is an
occasional drop of blood at the
site.
• You should watch your arm or leg
for changes in temperature,
color, pain, numbness, tingling,
or loss of movement.
• Drink plenty of fluids to help the
contrast leave your body. You
may not be able to do any
strenuous activities or take a bath
or shower for a period of time
after the procedure.
