Some invasive procedures are more
safely performed in a hospital based setting. The physicians at
Larchmont Imaging Associates also provide radiology services at
Virtua Memorial Hospital in Mount Holly, New Jersey. Below is
a summary of the interventional radiology services available at
that hospital.
Interventional Radiology
is an exciting specialty within Radiology. The tools and techniques
used in this field have numerous applications and are used in
the treatment of a wide variety of common disorders, including
peripheral vascular disease, oncology, spine, women’s and
men’s health, and hemodialysis access. An interventional
radiologist is a physician who has had a year of clinical internship
(either surgical or medical), four years of Diagnostic Radiology
residency, and a year of specialized training as a fellow in Interventional
Radiology. More information on Interventional Radiology can be
found at the Society
of Interventional Radiology.
Procedures currently performed by the Interventional Radiology
section at Virtua Memorial Hospital include, but are not limited
to:
- Myelograms
- CT Scan guided Biopsies
- Ultrasound Guided Biopsies
- Drainage Procedures
- Stereotactic Breast Biopsies
- Galactograms
- Arteriograms/Angiograms
- Arthrograms
Some of the procedures that are more commonly performed are described
below. We encourage you to discuss these options with your physician
or you can call the Interventional Radiology section at the hospital
at 609-267-0700 extension 43717.
Arterial Vascular Disease
Angiography: Angiography is a procedure for evaluating blood
vessels. The procedure is performed by inserting a catheter through
the groin artery. The catheter is then directed to the artery
to be studied. Radiographic contrast material is injected into
the artery, and digital X-rays are obtained. Angiography is performed
during all endovascular procedures, including angioplasty and
stent placement.
Angioplasty: Angioplasty is a procedure for treating diseased
blood vessels, and is performed during an angiography procedure.
Angioplasty uses a balloon to open areas of narrowing (stenosis)
or blockage (occlusion) within blood vessels. The balloon is inflated
for a short time, and is then removed after dilating the blood
vessel. Digital X-rays demonstrate the area of diseased blood
vessel to be treated.
Stent Placement: The use of stents is performed in conjunction
with angioplasty. Stents are tubes of metal scaffolding, which
are used to keep a blood vessel open following angioplasty. Stents
are permanent, and are used when angioplasty alone will not be
sufficient to treat a severely diseased vessel.
Thrombolysis: Thrombolysis is used to restore blood flow within
blocked (occluded) blood vessels or bypass grafts. The procedure
may involve the use of medicine to dissolve blood clots, or the
blood clots may be removed from the vessel through suction. When
thrombolysis is performed, angiography is also performed to study
the blood vessels affected by the clots. An angioplasty is also
performed to treat the underlying diseased blood vessel, which
caused the clot to form.
Angioplasty, stenting, and thrombolysis procedures can be used
to treat all diseased blood vessels, including the aorta, iliac
arteries, carotid arteries, renal arteries, and arteries to the
bowel, legs, and arms. Coronary (cardiac or heart) arteries are
treated by an interventional cardiologist.
Embolization (embolotherapy): Embolization techniques are elegant
approaches for treatment of a wide variety of diseases. In these
instances, embolization can be used to control life-threatening
hemorrhage, to allow for endovascular repair of abdominal aortic
aneurysms with a stent graft device, and to devascularize organs
prior to surgical removal for less operative blood loss. Additional
roles of embolotherapy are discussed under different subject headings.
Oncology
Chemoembolization: Chemoembolization is a procedure to treat
liver cancers, both primary and metastatic disease. The procedure
delivers a high concentration of chemotherapy to the liver using
a catheter. The catheter is removed following the procedure. Chemoembolization
has several benefits including higher concentration of chemotherapy
dose within the liver and reduced systemic side effects. A consultation
with an interventional radiologist will determine if you are eligible
for this procedure.
Radiofrequency Ablation: Radiofrequency ablation (RFA) is a procedure,
which can treat focal liver tumors, both primary and metastatic
disease. A probe is inserted into the tumor under ultrasound guidance
and a current is passed through the probe. This current raises
the temperature within the tumor, resulting in a thermal ablation
of the cancerous tissue. Other potential applications of RFA include
kidney, bone, lung, and breast cancers. A consultation with an
interventional radiologist will determine if you are eligible
for this procedure.
Implantable Infusion Ports: Implantable infusion ports are long-term
venous access devices frequently used to administer chemotherapy.
The port is placed under the skin, within the subcutaneous tissues
in the upper chest or upper arm. The procedure is performed with
local anesthetic and no discomfort. Your oncologist will determine
if you require this type of port, and can refer you to our Interventional
Radiology section.
Spine
Vertebroplasty: Vertebroplasty is a procedure to treat painful
compression fractures of the spine. A needle is inserted into
the vertebral body with a fracture and cement is injected. The
cement restores height to the vertebral body as well as offering
structural support, while eliminating the pain associated with
compression fractures. A consultation with an interventional radiologist
will determine if you are eligible for this procedure.
Women’s Health
Uterine Artery Embolization: Uterine artery embolization is indicated
for treatment of symptomatic uterine fibroids. Symptoms from uterine
fibroids may include abdominal and pelvic bloating, painful menstrual
periods, excessive menstrual bleeding, irregular menstrual periods,
painful sexual relations, lower back pain, and pressure on the
bladder/bowels. During the procedure, a catheter is directed to
the arteries that supply the uterus, and microscopic particles
are injected. The particles become embedded within the fibroids,
and serve to block the blood flow to the fibroids. The fibroids
die and shrink in size. A consultation with an interventional
radiologist will determine if you are eligible for this procedure.
Men’s Health
Testicular Vein Embolization: Testicular vein embolization is
a procedure that is used to treat symptomatic varicocele. Varicoceles
are dilated veins within the scrotum and may be a cause of male
infertility. During the procedure, a catheter is directed into
the veins that are responsible for the formation of the varicocele.
These veins are blocked with small stainless steel coils. The
procedure is performed on an outpatient basis. A consultation
with an interventional radiologist will determine if you are eligible
for this procedure.
Hemodialysis Access Maintenance
Dialysis Graft/Fistula Surveillance: Proper graft/fistula function
requires diligent surveillance. Grafts and fistulae are monitored
for proper function while you are receiving dialysis treatments.
If your nephrologist suspects that the graft or fistula is not
functioning properly, you may be scheduled for an evaluation.
A small needle is inserted into the graft or fistula, radiographic
contrast is injected, and digital images are acquired. If there
is an area of narrowing, it can be treated with a balloon (angioplasty).
Dialysis Graft Thrombolysis: Dialysis grafts that acutely become
occluded (sudden loss of pulse or “thrill”) can be
treated within a day or two using techniques similar to the surveillance
procedure (described above). The time required to open a clotted
graft is longer than the surveillance procedure, but the success
rate is quite high, and graft functionality can be restored.
Hemodialysis Catheter Insertion: Temporary dialysis catheters
are easily inserted through the neck veins. There are two types
of catheters: a non-tunneled and a tunneled type. Your nephrologist
will determine which type is most appropriate for your dialysis
requirements.
