ABSTRACT
The traditional treatment of high-flow vascular malformations consists of selective embolization, surgical removal, or a combination of both. Recurrence of the lesion and bleeding control are still the main problems, and the result of treatment is sometimes disappointing. We suggest treatment of these lesions with surgical ligation of the distal major feeding arteries followed by intravascular injection of a sclerosing agent (3% tetradecyl sulfate), and surgical excision and reconstruction when indicated. We have found this to be an effective treatment regimen. We present 14 cases of high-flow vascular malformations of the head and neck area treated with this approach, of which 4 cases developed skin necrosis. Three of these 4 cases of skin necrosis were later treated with skin grafting and, in 1 case, an upper arm skin tube flap was used for nasal tip reconstruction. Three cases underwent delayed reconstruction using tissue expanders. From a symptomatic and aesthetic point of view, preliminary satisfactory results were obtained. We feel that this approach is a good option for treating difficult, high-flow vascular malformations.
