Sclerotherapy of peripheral venous malformations: a new technique to prevent serious complications

Because of its extremely powerful sclerosing effect, in our experience, ethanol can be considered the most efficacious agent in the percutaneous treatment of peripheral venous malformations. To reduce the risk of ethanol reflux into the superficial veins or the central venous system, we developed a simple but very efficacious technique. After the time necessary to obtain the sclerosing effect, we drain the ethanol with the same needle used to inject. The purpose of this article is to describe the technique of sclerotherapy with 96% ethanol for peripheral venous malformations and its effectiveness in reducing the serious complications of alcohol.
