Randomized trial evaluates direct ablation of branch varicosities in varicose veins, suggesting limitations of the approach.

The aim is to assess the feasibility and early outcomes of directly ablating branch varicosities using a 980-nm diode laser.
Conducted between July and August 2005 with 17 patients (21 limbs); male:female ratio 7:10, mean age 50.1 years.
Performed endovenous laser ablation in incompetent saphenous veins followed by direct laser ablation of branch varicosities.
Evaluated patients at 1 week, and 1-, 3-, and 6-month intervals.
Technical success in branch varicosities was 71.4% (11 of 15 limbs).
Closure of treated saphenous veins was 100% at 1 month (11 of 11 limbs).
Successful ablation in varicose tributaries was only 54.5% (6 of 11 limbs) at 1 month, with a 9% incidence of skin burns.

Park et al. (2007) studied this question.
