Sadick N. Long-Term Results with a Multiple Synchronized-Pulse
1064 nm Nd:YAG Laser for the Treatment of Leg Venulectasias
and Reticular Veins. Dermatol. Surg. 2001;27:365-369.
Objective: The present study examined the clinical
efficacy and long-term follow-up (12 months) of patients treated
with the 1064 nm Nd:YAG laser technology.
Methods: Twenty-five female patients (mean age 37.6
years, Fitzpatrick skin types II-V) were treated with up to
three treatment sessions at 6-week intervals on a 5 cm2 surface
area of vessels utilizing the 1064 nm Nd:YAG laser with a
circulating cooling device. Treatment parameters were vessel
size 0.2-2.0 mm treated with a double pulse of 7 msec at 120
J/cm2 and vessel size 2.0-4.0 mm treated with a single pulse
of 14 msec, fluence 130 J/cm2, with a spot size of 6 mm. Improvement
was judged by double-blinded observer evaluation, macrophotographic
imaging, optical chromatography, and a patient evaluation
scale.
Results: Sixty-four percent of patients treated in
the present study achieved 75% or greater clearing of vessels
after a maximum of three treatment sessions. Optical chromatography
revealed statistically significant decreased chromophore intensity
(mean blueness reduction index of 41.2b-). Sixty-four percent
of patients were greatly satisfied with the results of the
laser treatment. Two patients manifested vessel recurrence
when examined at 6 and 12 months, respectively.
Conclusion: The 1064 nm Nd:YAG laser can produce effective
long-term photosclerosis of blue venulectasia and reticular
veins. The potential for recurrence should be recognized by
the vascular laser surgeon.
