[Vascular medicine and foam sclerotherapy for venous malformations]

Vascular medicine plays a determining role in the management of vascular malformation, especially venous malformations. Ideally, therapeutic decision should be made in a multidisciplinary staff meeting. Vascular medicine plays the leading role for diagnosis and duplex-Doppler evaluation of coagulation disorders, potentially associated with an assessment of treatment feasibility using chemical or thermic endovascular techniques. Potential adherence of compression therapy must also be evaluated. Decision trees often mention sclerotherapy for the management of venous malformations. Echo-guided foam sclerotherapy is preferred. The superiority of foam sclerotherapy over liquid sclerotherapy has been demonstrated. Indications and limitations of this specific treatment remain to be definitively determined, especially for treatments with radiological control. Side effects are now well described for the use of foam sclerotherapy for venous malformations. They remain limited. Future developments should help optimize the sclerosing effect of currently used foams or other products to be developed. For the vascular medicine specialist, the main contribution is to define the appropriate use of echo-guided sclerotherapy.
