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 are awake for this procedure. 

First, your interventional radiologist numbs the skin on your abdomen with a local anesthetic so you won’t feel pain on the area being treated. They then use ultrasound guidance to insert a needle into the peritoneum, the area around the abdominal organs where fluid builds up. They use the needle to draw out between one and four liters of the excess fluid, depending on what’s necessary. They may need to repeat this process several times to remove all the fluid. Altogether, the procedure may take between 20 and 50 minutes, depending on how much fluid needs to be removed.

After enough fluid is collected, your doctor removes the needle and puts a bandage or dressing over the injection site. The fluid will be sent to a lab to make sure you don’t have an infection. This is an outpatient procedure, meaning you can return home after the procedure is complete. You can resume normal activities within a few days.
