Radiofrequency ablation for treatment of symptomatic low-flow vascular malformations after previous unsuccessful therapy.

Three patients with low-flow soft-tissue vascular malformations were treated with radiofrequency (RF) ablation. Other treatment options had proven unsuccessful. After RF ablation treatment, two patients were free of symptoms and one reported decreased symptoms followed by a return of symptoms within 1 year. No procedure-related complications occurred. It is suggested that RF ablation may be offered as an alternative treatment option for symptomatic vascular malformations when others have failed or are not possible.
