Objective To evaluate the effectiveness and safety of dual-wavelength laser in treating the resistant port-wine stains (PWS).
Methods Sixteen patients with single wavelength pulsed dye laser (PDL)-resistant PWS were subsequently treated with a dual-wavelength laser (595 nm and 1064 nm combination) in our department from January 2009 to December 2011. Their outcomes were recorded and retrospectively analyzed.
Results Of the 16 patients, 2 were cured, 6 markedly effective, 6 effective, and 2 ineffective. Vesiculation and scarring were seen in 3 and 2 patients, respectively, whereas no other adverse effects were reported.
Conclusion The novel dual-wavelength (595 nm and 1064 nm) laser is an effective and safe device for PWS that is resistant to PDL therapy alone.
