Venous and arteriovenous vascular malformations: diagnostic and therapeutic considerations regarding 239 patients observed in the 1978-1991 period.

The Authors report their experience in the treatment of venous and arteriovenous malformations, which in this paper are divided into two subgroups, pure venous malformations (VMs) and arteriovenous malformations (AVMs). A pure surgical indication was evident in less than 50% of cases (48.1%), while more conservative treatments were performed in remaining patients. Considering the particular characteristics of the disease, a complete surgical radicality isn't always possible, so surgery must be considered in selected cases.
