- Tumor Ablation Therapies for Cancer
(e.g. Radiofrequency heat ablation, Cryoablation):
Radiofrequency ablation is minimally invasive
method that uses thermal energy to destroy tumor
cells. Initially computed tomography or ultrasound
is performed to locate the tumor. A special needle
is introduced into the tumor using direct image
guidance. This is equivalent to a standard needl
e biopsy. The needle is attached to a radiofrequency
generator. The generator sends radiofrequency through
the needle, which generates heat from frictional movement
of ions. The heat destroys the tumor cells.
- Endo
Venous Ablation of Varicose Veins:
This minimally-invasive treatment is an outpatient procedure
performed using imaging guidance. After applying local anesthetic
to the vein, the interventional radiologist inserts a thin catheter
into the vein and guides it up the great saphenous vein in the thigh.
Then laser or radiofrequency energy is applied to the inside of the
vein. This heats the vein and seals the vein closed.
- Chemoembolization of
Liver Cancer:
Delivers cancer-fighting medications directly to the site of a
cancer tumor. Primarily used to treat liver cancers but also used
in malignant melanoma.
- Uterine Fibroid Embolization:
UFE is a minimally invasive treatment for fibroid tumors in the
uterus. In a uterine fibroid embolization procedure, physicians use
image guidance to place a synthetic material called an embolic agent
inside one or more of the blood vessels that supply the fibroid tumors
with blood. As a result, these vessels become occluded, or closed
off, and the fibroid tissue shrinks. In most cases, symptoms are relieved.
- Biliary
Drainage and Stenting:
Uses a stent (small mesh tube) to open up blocked ducts and
allow bile to drain from the liver.
- Varicocele
Embolization:
A treatment for "varicose veins" in the scrotum, which can cause male
infertility and pain.
- Vertebroplasty:
A pain treatment for fractured vertebra in which medical-grade
bone cement is injected into the vertebra.
- Angioplasty
The use of a small balloon on the tip of a catheter inserted
into a blood vessel to open up an area of blockage inside the vessel.
- Embolization
The insertion of a substance through a catheter into a blood vessel
to stop hemorrhaging, or excessive bleeding or to occlude blood supply
of a tumor.
- Gastrostomy tubes
A gastrostomy tube (feeding tube) is inserted into the stomach
if the patient is unable to take food by mouth.
- Stent placement
A tiny, expandable coil, called a stent, is placed inside
a blood vessel at the site of a blockage. The stent is
expanded to open up the blockage.
- Foreign body extraction
The use of a catheter inserted into a blood vessel to retrieve a
foreign body in the vessel.
- Needle biopsy
A small needle is inserted into the abnormal area in almost
any part of the body, guided by imaging techniques, to obtain
a tissue biopsy. This type of biopsy can provide a diagnosis
without surgical intervention. An example of this procedure
is called the needle breast biopsy.
- Blood clot filters
A small filter is inserted into a blood clot to catch
and break up blood clots.
Injection of clot-lysing agents - clot-lysing agents, such
as tissue plasminogen activator (TPA), are injected into
the body to dissolve blood clots, thereby increasing blood
flow to the heart or brain.
- Catheters insertions
A catheter is inserted into large veins for giving chemotherapy
drugs, nutritional support, and hemodialysis. A catheter may also
be inserted prior to bone-marrow transplantation.
- Angiography
An x-ray of the arteries and veins to detect blockage or
narrowing of the vessels. In many cases, the interventional
radiologist can treat the blockages, such as those occurring
in the arteries in the legs or kidneys, by inserting a small
stent which inflates and opens the vessel. This procedure is
called a balloon angioplasty.
