The HECOVAN working group is a multidisciplinary task force at the Radboudumc  that pursues the study and treatment of hemangiomas and both congenital and non-congenital vascular malformations. Participating specialisms include dermatology, plastic surgery, interventional radiology, vascular surgery and oral- and maxillofacial surgery (OMFS). When necessary, we also consult with neurologists, pediatricians, internists, ophthalmologists, ENT specialists or orthopedists.

Diagnostics and treatment

The Hecovan group has a wide array of diagnostic and treatment facilities at its disposal. In an interdisciplinary set-up the most fitting treatments are chosen. For example:

  • alcohol embolization of arteriovenous, venous and macrocystic lymphatic malformations;
  • intralesional Bleomycin injections of lymphatic malformations;
  • treatment with Aethoxysklerol (foam) of superficial venous or lymphatic malformations;
  • vascular surgical and plastic surgical interventions;
  • treatment after care and counselling of children with (ulcerating) hemangiomas.
