Interventional Radiology for the Brain

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.

Embolization

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.

Thrombolysis

Blood clots by injecting clot-busting drugs at the site of the clot. Treats blood clots in the brain to reverse the effects of stroke; treats deep vein thrombosis in the leg to prevent permanent disability.

Devices

Stent

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).
