Interventional radiologists use imaging technology and a thin needle to safely drain infected fluid out of wounds or abscesses in the body. The fluid can be studied in a lab to diagnose the type of infection you have.

The University of Miami Health System interventional radiologists perform drainages to improve healing. These procedures cause little discomfort, but they may help relieve some symptoms of your infection.

Who is a Candidate?


Your doctor may recommend drainage if you have an abscess or infected wound.


What to Expect


Your interventional radiologist may advise you to stop taking aspirin, nonsteroidal anti-inflammatory drugs (NSAIDs), or other blood-thinning medicines before your procedure. You receive sedation to help you stay comfortable. Your doctor also applies a local anesthetic to numb the area where they will insert the needle.

After the area is numbed, your interventional radiologist uses ultrasound or computed tomography (CT) to guide the thin needle into the abscess and draw out a sample of fluid. This fluid is sent to the lab for testing.

Your doctor may then insert a catheter (thin, flexible tube) into the abscess and leave it in place. The catheter is connected to a bag that collects fluid that drains off the abscess. You have the catheter and drainage bag in place until fluid stops draining or your infection is gone. At that time, your doctor removes the catheter and puts a bandage or dressing on the insertion site. The entire procedure takes about 20 minutes.
