- Retrospective review of 197 infants (73 boys, 124 girls), mean age of first treatment 3.38 months (range, 5-355 days) with Fitzpatrick skin types I –VI, treated for port-wine stains.
- Vbeam Perfecta (595-nm PDL) parameters (determined by PWS location): spot size 10 to 12 mm, fluence 6.5 to 9.0 J/cm2 and pulse duration of 0.45 to 1.5 ms.
- Mean number of treatments was 9.8 (range 2-23, mean interval of 37.29 days). Topical or general anesthesia was not administered.
- Independent grading by 4 physicians of clinical photography (before and 1 year after the initial treatment), using a 5-point scale: poor (0%-25%), fair (26%-50%), good (51%-75%), excellent (76%-99%), and complete (100%) clearance.
- 67% of all patients showed >75 to 100% improvement.
- Mean grade for all patients was 3.65±1.26, corresponding to excellent clearance.
- None of the patients experienced scarring or permanent pigmentary change.
- All of the patients with darker skin types (IV - VI) did well, without any significant complications.
