Endovenous laser treatment

Endovenous laser treatment (EVLT) is a way of treating abnormal and enlarged veins so that they shrink and become less troublesome. This page from Great Ormond Street Hospital (GOSH) explains about endovenous laser treatment (EVLT), why it might be suggested and what to expect when your child comes for treatment. 

Embolisation

Embolisation is a way of blocking abnormal blood vessels. This page from Great Ormond Street Hospital (GOSH) explains about embolisation, why it might be suggested and what to expect when your child comes to GOSH for treatment. 

Drainage or aspiration of fluid by Interventional Radiology

Fluid can build up inside the body for many reasons. Small amounts of fluid can be drawn off using a needle and syringe. This is called aspiration. Larger amounts or thicker liquid will need to be drained over a period of time using a thin plastic tube. This page from Great Ormond Street Hospital (GOSH) explains about the procedure to drain or aspirate fluid from the body, what it involves and what to expect when your child comes to the Interventional Radiology department for treatment.

Liver biopsy

The liver is the largest organ in the body and is located in the top right hand side of the abdomen. It makes proteins that travel around in the blood, and also breaks down waste products so they can be passed out in urine (wee) or faeces (poo). This page from Great Ormond Street Hospital (GOSH) explains what happens when your child has a liver biopsy. 

Biopsy

A biopsy is a small sample of tissue taken from the body so it can be examined under a microscope and tested chemically in the laboratories. This page from Great Ormond Street Hospital (GOSH) explains about the procedure to take a biopsy in the Interventional Radiology department. 

Angiography and angioplasty

Angiography is a procedure that allows doctors to look at blood vessels in great detail using X-rays. If the doctors identify a narrowed portion (stenosis) of a blood vessel during the angiography procedure, they may stretch or widen it straightaway using a procedure called an angioplasty. This page from Great Ormond Street Hospital (GOSH) explains about an angiography and angioplasty procedure, what it involves and what to expect when your child comes to GOSH have one.

MRI scans

An MRI (magnetic resonance imaging) scan uses a magnetic field rather than x-rays to take pictures of your child’s body. The MRI scanner is a hollow machine with a tube running horizontally through its middle.

Long-term EEG monitoring (telemetry)

Telemetry is a test that looks at the function of the brain. The brain works by a series of nerve impulses, which cause electrical signals. These signals (also called brainwaves) can be recorded through the scalp. This page from Great Ormond Street Hospital (GOSH) explains the procedure for a telemetry test and what to expect when your child has one.
