Endovenous radiofrequency thermal ablation and ultrasound-guided foam sclerotherapy in treatment of klippel-trenaunay syndrome.
BACKGROUND
Klippel-Trenaunay syndrome is composed of port-wine stain, limb hypertrophy and varicose veins.


METHODS
The two patients with Klippel-Trenaunay syndrome treated by endovenous radiofrequency thermal ablation and ultrasound-guided foam sclerotherapy of the abnormal veins was conducted.


RESULTS
Radiofrequency thermal ablation resulted in successful occlusion of the incompetent anterior accessory great saphenous vein. Moreover, ultrasound-guided foam sclerotherapy showed complete occlusion of the residual veins. At 6 month follow-up, both patients markedly decreased leg symptoms including pain, cramping, limb swelling, and bulging of veins.


CONCLUSIONS
Radiofrequency thermal ablation combined with foam sclerotherapy is a minimally invasive procedure alternative to the standard invasive surgery and can be the option for saphenous ablation in Klippel-Trenaunay syndrome patients.
