Effect of electrochemical treatment on high-flow vascular malformations in the maxillofacial region

We explored the effect of electrochemical therapy for the treatment of high-flow venous malformations in the maxillofacial region in 32 patients. We used a method of anaesthesia that was suitable to the site and size of the lesion, and then inserted platinum needles into the lesion in a sterile environment. We protected the normal skin by inserting the cannulas into plastic sheaths, and connected the needles to an electrochemical machine. The common voltage, electric current, and amount of electricity were 6-8 V, 80-100 mA, and 10-20 C/cm(2), respectively. During a follow up period of two months to three years, 18 (56%) patients had a complete response, and 14 a partial response (44%). Electrochemical treatment is a simple, relatively atraumatic method of dealing with high-flow venous malformations that leaves no scars.
