In many cases, interventional radiologists can open blocked or narrowed blood vessels caused by peripheral arterial disease or other conditions. In some patients, high blood pressure is caused by a blockage to the artery to the kidney, a condition known as renal vascular hypertension. Interventional radiologists can often treat blocked blood vessels without surgery. In most cases, hospitalization and general anesthesia are not required. There is no incision - just a small nick in the skin - and no stitches are required. Often, patients may return to normal activity shortly after the procedure.
During angioplasty, the interventional radiologist inserts a very small balloon attached to a thin tube (catheter) into a blood vessel through a small incision. The catheter is threaded under X-ray guidance to the site of the blocked artery. The balloon is inflated to open the artery. A small metal scaffold/tube, called a stent, is sometimes inserted to hold the blood vessel open.
Thrombolytic therapy is used if the blockage in an artery is caused by a blood clot. Thrombolytic drugs that dissolve clots are injected through a catheter to eliminate the clot and restore the blood flow.
The most common interventional procedures are listed below, with links to patient information sheets.
- Breast Needle Localization
- Microwave ablation
- Radiofrequency Ablation - Lung, Liver, or Renal (Kidney)
- Uterine Fibroid Embolization
