[Surgical treatment of vascular malformations in children and adolescents]. / Chirurgische Therapie vaskulärer Malformationen bei Kindern und Jugendlichen.

ABSTRACT

Vascular malformations are inborn errors of vasculogenesis in localised regions of the body. They are present at birth and grow proportionally with the child without ever showing any tendency to regress. This fact distinguishes them clearly from haemangiomas, which represent vascular tumours with high proliferation during the first year of life followed by a slow involution thereafter. The strategy for the treatment of vascular malformations differs substantially from the one for haemangiomas. According to the type of vascular malformation, the treatment may consist in laser therapy, sclerotherapy, selective embolisation, and/or surgical resection. Whereas systemic medication may save the life of children with life-threatening haemangiomas, such treatment would have no significant effect in children with vascular malformations. The aim of the surgical treatment is to perform a complete resection of the malformation in order to prevent its recurrence. However, since vascular malformations often have an infiltrative growth, frequently only subtotal resections can be performed to avoid unacceptable functional or cosmetic disfigurement of the body. Generally, an optimal management of children with vascular malformations includes a multidisciplinary approach with critical consideration of all potential treatment procedures.
