Special Procedures & Interventional Radiology
Some radiological procedures must be performed by a small incision in the skin. Many are performed on a one-day surgery basis, eliminating the need for a hospital stay.
Angiography is a procedure that is often used to diagnose disorders of the arteries. With angiography, a physician guides soft, flexible tubes (catheters) through the blood vessels. The physician then injects a material that is visible on x-rays and allows the physician to evaluate the arteries. If found, partial blockage can often be treated with balloon angioplasty and intravascular stents to improve blood flow.
Other special procedures include:
- Needle biopsies of the lungs, liver, pancreas, kidneys and other organs
- Draining abscesses and obstructed kidneys and livers
- Myelograms to study the spine
- Thrombolytic therapy to dissolve blood clots
- Venograms to study veins
- Inferior Vena Cava filters to prevent blood clots that form in the legs and pelvis from passing to the lungs, where they can be fatal
