What is an intranodal lymphangiogram?

The lymph nodes and vessels are not detected with regular imaging. An intranodal lymphangiogram is a minimally invasive procedure done by interventional radiologists to highlight the lymph system. A dye is injected into the lymph nodes in the groin and then fluoroscopy is used to visualize and check for blockage or leaks.

Why would you need an intranodal lymphangiogram?

This procedure is generally performed on patients with chylous ascites. Chylous ascites (this will be a link) refers to accumulation of lipid-rich fluid in the abdominal cavity. It is primarily due to trauma or obstruction to the lymphatic system. The most common cause of this is malignancy. It may also occur after abdominal surgery.

Risks Involved

Our ability to use imaging guidance and cutting-edge technology minimizes patient risk. Prior to your procedure, your physician will discuss any potential risks with you.
Conditions to let us know about
Let your doctor know if you currently are pregnant or breast feeding, feeling ill, have a fever, or are taking any blood thinners.

Insurance coverage

Lymphangiogram is covered by most private insurance providers as well as Medicare. We will seek authorization from your insurance company prior to your procedure.

Preparing for your procedure

If you are on blood thinners your doctor will instruct you if you need to stop these medications prior to the procedure. If your procedure requires sedation, then you will need a responsible adult to give you a ride home.

Recovering from your procedure

You may possibly receive mild to moderate sedation during your procedure. You will stay in the recovery area until you are ready for discharge. You will be given written post procedure discharge instructions that will advise you about return to normal physical activity. If you have any questions after your procedure, please call the RIA Interventional Suite at 720-493-3406.
