[Current management of venous malformations].

Venous malformations represent 2/3rds of all vascular malformations and are frequently much more complex than they appear to be. Patients with large venous malformations require a deep analytical and radiological study, as well as specific treatment to control any possible localised intravascular coagulation. If the lesions are extensive, especially in the lower member, a study should be made to detect the presence of an underlying osteoporosis with the idea of preventing pathological fractures. Equally, a check must be made for arthropathy, and an early prophylactic synovectomy must be considered when the radiological extension makes this advisable, with the idea of avoiding irreversible damage to the joints with the passage of time. Currently, microfoam scleropathy is favoured as the treatment of choice for low-flow vascular malformations. In the not too distant future, the use of selective antiangiogenic medicines, besides low-molecular-weight heparins, will serve to control and treat malformations.
