Coronavirus Update:What patients and families need to know



Embolization means introducing a foreign substance into a blood vessel to stop the flow of blood. 

Esophageal Dilatation

The esophagus, which is the tube that carries food from the mouth to the stomach, can become narrowed and cause swallowing difficulty. Causes of this narrowing include stricture formation, usually after surgery, allergies, or even injury from caustic substances. Dilatation is when a high-pressure balloon is inserted into the esophagus and inflated to open up these narrowed portions.

G-J Tube

A G-J tube is just like a G-tube (see “Percutaneous Gastrostomy Tube) except that it contains an extra portion of tubing that extends from the stomach to the intestine.

Joint Injections

Joint injections are used to treat children with arthritis. High-dose steroids are directly injected into the diseased joint spaces.

Lumbar puncture

A lumbar puncture is when a physician inserts a needle in the lower spine to obtain cerebrospinal fluid in search of infection, administer chemotherapy, or monitor and relieve cerebrospinal fluid pressure. Learn more.

Magnetic Resonance High Intensity Focused Ultrasound (MR-HIFU)

A Magnetic Resonance High Intensity Focused Ultrasound (MR-HIFU) is a procedure in which a radiologist uses the aid of magnetic resonance imaging to focus an ultrasound beam into lesions, usually tumors of the bone, to heat and destroy the tissue in that region.

Nephrostomy Tube

A nephrostomy tube is inserted into the kidney to help drain urine when the flow is otherwise blocked.


A paracentesis is a procedure in which fluid is drained from the abdominal cavity, which is the space that lies between the abdominal organs, like the liver, and the abdominal wall.

Percutaneous Gastrostomy Tube

A percutaneous gastrostomy tube is a plastic passageway for certain types of nutrition and medication directly into your child’s stomach, through the skin. Also known as a “G-tube,” it is created by making a small opening with a needle over the abdominal wall.

Percutaneous Transhepatic Cholangiogram

A percutaneous transhepatic cholangiogram, or PTC, is an X-ray of the bile ducts (also called the biliary ducts). Radiologists and other doctors use the images to determine if the ducts are underdeveloped or blocked.
