Helping your teenager through transition from GOSH to adult neuromuscular services

Transition is a planned process. It aims to:
  • support teenagers in the development of skills to become more independent in their healthcare
  • support parents in helping their teenager to achieve this to the best of their ability and
  • prepare for transfer from child-centred healthcare to adult healthcare services. 
This page from Great Ormond Street Hospital (GOSH) offers you some suggestions about how you might help your teenager to move through transition.


A splenectomy is an operation to remove the spleen. It can be carried out using keyhole surgery or traditional open surgery. Most splenectomies at GOSH are carried out using keyhole surgery.

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.

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.
