Guidelines for the treatment of head and neck venous malformations.
On the basis of the results of preliminary animal experiments, electrothrombosis was clinically utilized as a treatment for cirsoid angioma or varicosis. Seven patients with cirsoid angioma of the head and neck and two patients with varicosis of the leg treated by electrothrombosis technique are presented. Six were improved by electrothrombosis alone to the extent that no further treatment was required, while in three with angiomas, further surgery was needed to reduce the mass to normal size. The preceding use of electrothrombosis decreased the bleeding significantly. During follow-up from 18 months to 7 years, neither recurrence nor postoperative complications were encountered.
