Abstract
Arteriovenous malformation is treated by variety of techniques over the years. Sclerotherapy is considered an effective and conservative technique for the treatment of benign vascular lesions and replaced the traditional role of surgical therapy, especially for the venous lesions that are surgically difficult or at inaccessible areas. Absolute ethanol was adopted as a new sclerosant agent for this complex form of venous defects to improve overall treatment results with acceptable morbidity and recurrence rates. Sclerotherapy has the advantage of no external scaring, low cost, and few complications in comparison to the surgical treatment.
