The sclerosing therapy in congenital vascular defects.

In most of the cases of angiodysplasias sclerotherapy is a palliative treatment. Its aim is to alleviate some disgracious consequences of secondary venous insufficiency caused by the primary malformation. Nevertheless sclerotherapy can be proposed to cure some primary malformation radically such as small venous angiomas or to reduce extensive angiomas before a surgical procedure.
