Common Interventional Procedures


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. Click here for details.

Balloon angioplasty

Opens blocked or narrowed blood vessels by inserting a very small balloon into the vessel and inflating it. Used by IRs to unblock clogged arteries in the legs or arms (called peripheral vascular disease or PVD), kidneys (called portal hypertension), brain or elsewhere in the body. Click here for details.

Biliary drainage and stenting

Uses a stent (small mesh tube) to open up blocked ducts and allow bile to drain from the liver. Click here for details.

Central venous access

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. Click here for details.


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. Click here for details.


Delivery of clotting agents (coils, plastic particles, gel, foam, 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. Click here for details.

Fallopian tube catheterization

Uses a catheter to open blocked fallopian tubes without surgery; a treatment for infertility. Click here for details.

Gastrostomy tube

Feeding tube inserted into the stomach for patients who are unable to take sufficient food by mouth. Click here for details.

Hemodialysis access maintenance

Use of angioplasty or thrombolysis to open blocked grafts for hemodialysis, which treats kidney failure. Click here for details.

Needle biopsy

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

Radiofrequency (RF) ablation

Use of radiofrequency (RF) energy to Acook@ and kill cancerous tumors. Click here for details.


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). Click here for details.


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 endograph. Click here for details.


Dissolves blood clots by injecting clot-busting drugs at the site of the clot. Click here for details.

TIPS (transjugular intrahepatic portosystemic shunt)

A life-saving procedure to improve blood flow and prevent hemorrhage in patients with severe liver dysfunction. Click here for details.

Uterine artery embolization

An embolization procedure of uterine arteries to stop life- threatening postpartum bleeding, potentially preventing hysterectomy. The same procedure is used to treat fibroid tumors and is then called UFE (Uterine Fibroid Embolization). Click here for details.

Uterine fibroid embolization

An embolization procedure of uterine arteries to shrink painful, enlarged, benign tumors in the uterus, also called UAE (Uterine Artery Embolization). Click here for details.
