The radiology department provides the following interventional services:
Opens blocked or narrowed blood vessels by inserting a very small balloon into the vessel and inflating it. Used by interventional radiologists to unblock clogged arteries in the legs or arms (called peripheral vascular disease, or PVD), kidneys, brain, and elsewhere in the body.
Biliary tube or stent drainage and stenting
Uses a stent (small wire mesh device) to open up blocked ducts and allow bile to drain from the liver as it should.
Delivery of clotting agents (coils, plastic particles, gelfoam, etc.) directly to an area that is bleeding or to block blood flow to a problem area, such as an aneurysm or a fibroid tumor in the uterus.
Hemodialysis access maintenance
Use of angioplasty or thrombolysis to open blocked grafts for hemodialysis, which treats kidney failure.
Needle biopsy/bone biopsy
Diagnostic test for breast, lung and other cancers—an alternative to surgical biopsy. Can be used to obtain diagnostic tissue from almost anywhere in the body.
An x-ray exam of arteries and veins in the lungs to diagnose thrombosis (clot) and other blood vessel problems; uses a catheter to enter the blood vessel and a contrast agent (x-ray dye) to make the artery or vein visible on the x-ray.
Radiofrequency (RF) ablation
Use of RF energy to heat and kill cancerous tumors.
