[Microwave ablation of the spleen: An easy and gentle method for treatment of secondary splenomegaly in children. A case report].

Portal hypertension (PHT) in children may be caused by many different liver and vascular diseases and can lead to life threatening complications such as splenomegaly with thrombocytopenia. The treatment of choice for symptomatic splenomegaly is Partial Splenic Embolization (PSE) which is effective but painful, and therefore not offered to children younger than 10 years of age at the Karolinska University Hospital in Stockholm.  Percutaneous microwave ablation (MWA) is a well-established method in adults for the treatment of tumors in the liver and other organs.
