RAD 211~ INTERVENTIONAL RADIOLOGY STUDY
GUIDE
Interventional imaging procedures - Answers - Radiologic procedures that intervene in
a disease process, providing a therapeutic outcome.
- Less expensive than traditional methods and surgical methods
- Shorter hospital stays for the patient
- Shorter recovery time
- Alternatives for patients who are not candidates for surgery - Answers - Benefits of
the patient and the healthcare system:
deep vein thrombosis (DVT) - Answers - Clot that forms in a deep vein, usually in the
leg
- reduce or stop blood flow
- increase blood flow
- remove foreign bodies
- other
- TIPS - Answers - Four main divisions of Vascular interventional radiology:
Embolization - Answers - Procedure that uses an angiographic approach to create and
embolus in a vessel, restricting blood flow.
Uterine Fibroid Embolization - Answers - - Used to treat symptomatic fibroids. Small
microspheres or beads are injected into the uterine artery cutting off blood supply to the
fibroid.
- Can shrink fibroids and eliminate associated pain and bleeding, replacing the need for
a hysterectomy.
Chemoembolization - Answers - a palliative treatment for liver cancer
Embolization - Answers - - Stops blood flow to a site of pathology
- Reduce blood flow to a highly vascular structure and tumor before surgery
- Stop active bleeding at a site
- Deliver a chemotherapeutic agent
- three chemotherapy drugs are injected into the artery that supplies blood to the tumor
in the liver
- The artery is then blocked off (embolized) with a mixture of oil and tiny particles
- Survival rate is comparable to much more invasive surgeries.
- Exploring the opportunity to use it for other cancers (lung, breast, brain) - Answers -
What happens during chemoembolization?
, Fibroids - Answers - muscular tumors that grow in the wall of the uterus
Percutaneous transluminal angioplasty - Answers - Uses an angiographic approach
and specialized catheters to dilate a stenosed vessel.
- Catheter with a deflated balloon is advanced to the vessel of interest, then inflated.
- Pressure is monitored before, during, after inflation to prevent rupture
- May need to be inflated more than once, but time is limited as the vessel is blocked
off during inflation - Answers - What happens during a Percutaneous Transluminal
Angioplasty?
Stent placement - Answers - Cage like metal device that is placed in the lumen of a
vessel to provide support
Self expanding - Answers - Automatically expands when the stent cover is removed
from the vessel
Balloon expanding - Answers - placed during the balloon inflation phase of the
angioplasty
Pharmacologic agent - Answers - Most stents contain a _____________ _______ that
inhibits the regrowth of vascular tissue within the artery, preventing restenosis
stent-graft placement - Answers - combination of interventional stents and surgical
grafts
aortic aneurysms and traumatic vascular injuries - Answers - Primary indications for a
stent-graft placement include:
leakage around the stent, migration of the stent, and rupture of the vessel - Answers -
Complications of a stent-graft include:
Catheter is advanced, stent-graft self expands once in place, and adheres to the vessel
wall. - Answers - What happens during a stent-graft placement?
are not surgical candidates, or for patients who want a lower risk option compared to
surgery - Answers - A stent-graft placement is an option for patients who:
- Peripherally Inserted Central Catheter (PICC line)
- Central Line
- Subcutaneous Ports - Answers - Types of venous access devices:
Peripherally Inserted Central Catheter (PICC line) - Answers - Proximal tip is
positioned near the right atrium, distal end remains exposed (usually on an upper
extremity)
