We transfer seriously ill children to Europe for specialised surgery. Tdh is the European leader in medical evacuations and organises 40% of these. Back home, post-operative medical follow-up is provided and the children are supported in their reintegration into school. In collaboration with cardiology specialists from the CHUV in Lausanne, we organise surgical missions to Dakar. The aim of them is to consult, treat and operate on sick children in their country of origin, while strengthening the skills of local health personnel. La Chaîne de l'Espoir has set up a paediatric cardiac surgery centre within the Fann University Hospital in Dakar. This increases the number of children operated in their country. Theoretical and practical trainings are provided for the Master's course in paediatric cardiac surgery.
