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?
