Paracentesis
Removal of excess abdominal fluid from the abdomen
Liver disease, cancer, heart failure, and kidney disease are a few examples of conditions that can lead to a buildup of excess fluid in the abdomen.
This fluid, also called ascites, can put pressure on abdominal organs and cause discomfort for the patient.
When this occurs, an interventional radiologist may be called upon to drain the fluid in a minimally invasive procedure.
The interventional radiologist will use ultrasound imaging to look for a safe entry into the pocket of fluid.
The patient’s skin is then numbed and a small tube is inserted into the fluid through the skin.
Mild suction is used to draw the fluid out of the abdominal cavity into a jar or bag.
The fluid may then be tested to help guide treatment or make a diagnosis.
Paracentesis is an outpatient procedure that typically does not require anesthesia.
Local anesthetic will be used to numb the skin where the interventional radiologist will be entering the body.
