Interventional Radiology for the Heart & Lungs



An x-ray exam of the arteries and veins to diagnose blockages 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.

Needle biopsy

Diagnostic test for breast, lung and other cancers; an alternative to surgical biopsy.

PVD Scan

A Doppler exam for peripheral vascular disease quickly determines if there is any impairment in the circulation to the limbs and identifies blockages in the leg arteries.

Treatments and Procedures

Balloon angioplasty

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 or elsewhere in the body.

Central venous access (CVAC)

Insertion of a tube beneath the skin and into the blood vessels so that patients can receive medication or nutrients directly into the blood stream or so blood can be drawn.

Chemoembolization - Types of Cancer Treated: Bone, Breast, Kidney, Liver and Lung

Delivery of cancer-fighting agents directly to the site of a cancer tumor; currently being used mostly to treat cancers of the endocrine system, including melanoma and liver cancers.


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.



A small flexible tube made of plastic or wire mesh, used to treat a variety of medical conditions (e.g., to hold open clogged blood vessels or other pathways that have been narrowed or blocked by tumors or obstructions).


Reinforces a ruptured or ballooning section of an artery (an aneurysm) with a fabric-wrapped stent C a small, flexible mesh tube used to "patch" the blood vessel. Also known as an endograft.

Vena cava filter

A tiny cage-like device that is inserted in a blood vessel to break up clots and prevent them from reaching the heart or lungs. Prevents pulmonary embolism.
