Venous sclerotherapy

Venous sclerotherapy is a procedure used to treat venous malformations. Venous malformations are made up of extra veins that have no use and cause problems. This page explains about venous sclerotherapy, why it might be suggested and what to expect when your child comes to Great Ormond Street Hospital (GOSH) for the procedure. 

Thrombolysis and thrombectomy

Blood contains cells called platelets and a substance called fibrinogen that allow the blood to clot. In normal circumstances, clotting is a good thing as it prevents blood loss from an injury such as a cut or graze. However, when a blood clot forms inside a blood vessel, it can cause serious problems. This page from Great Ormond Street Hospital (GOSH) explains about how a blood clot is diagnosed and the various forms of treatment (thrombolysis and thrombectomy) that may follow.

Tube oesophagram 

A tube oesophagram is a specialised type of imaging scan used when a child is suspected of having a tracheo-oesophageal fistula. Tracheo-oesophageal fistula (TOF) is a rare condition, where part of the oesophagus (gullet or foodpipe) is joined (fistula) to the trachea (windpipe).This information sheet from Great Ormond Street Hospital (GOSH) explains about the tube oesophagram procedure, what it involves and what to expect when your child comes to GOSH to have one.

Pain relief using Entonox®

When coming into hospital, children, young people and their families are often worried that they may be in pain. Entonox® is a gas – a mixture of half oxygen and half nitrous oxide that is used for pain relief. Entonox® can also be called ‘gas and air’ or ‘laughing gas’. This page from Great Ormond Street Hospital (GOSH) explains how Entonox® works, when it is most suitable and what to expect when your child uses Entonox® for pain relief. 

Encouraging your child to produce a healthy voice

There are many reasons why children’s voices may sound different in quality, loudness or pitch, to those of their friends, brothers and sisters. Your child’s speech and language therapist and/or ENT doctor will explain the specific reason why your own child is having voice difficulties. Whatever the reason, we know that there are certain things that your child can do to make the most of their voice. There may also be things that they are doing that make the problem worse. This page from Great Ormond Street Hospital (GOSH) is designed to help you to encourage your child to produce a healthy and efficient voice.

Kidney biopsy

A biopsy is a small sample of tissue taken from any area of the body so it can be examined under a microscope. A sample of kidney tissue may be taken using an endoscope (a thin, flexible tube with a bright light and camera). This page from Great Ormond Street Hospital (GOSH) explains the kidney biopsy procedure and what to expect when your child comes to GOSH to have one.
